Vibrational stress relief (VSR) treatment as a method of stress relief is currently performed on different alloys and sizes as an appropriate alternative for thermal stress relief (TSR) method. Although many studies have been performed to extend the knowledge about this process, analytical studies in the field of VSR process seems to require wider efforts to introduce the concept more clearly and extensively. In this study, a theoretical model is proposed based on an analytical equation. The proposed equation was modified in terms of required variables including frequency, amplitude, and vibration duration to encompass more practical parameters compared to the previous models. Thus, essential VSR parameters including the number of cycles as a representative of treatment duration, strain rate as a representative of frequency, and the amplitude were embedded in the model to make it comprehensively practical. Experimental tests were also performed and residual stress distribution was measured by X-ray diffractometry (XRD) method for certain points to compare the experimental results with the theoretical output. An acceptable range of conformation was observed between theoretical and experimental results.

The structural damages can lead to structural failure if they are not identified at early stages. Different methods for detecting and locating the damages in structures have been always appealing to designers in the field. Due to direct relation between the stiffness, natural frequency, and mode shapes in the structure, the modal parameters could be used for the purpose of detecting and locating the damages in structures. In the current study, a new damage indicator named “DLI” is proposed, using the mode shapes and their derivatives. A finite element model of a beam is used, and the numerical model is validated against experimental data. The proposed index is investigated for two beams with different support conditions and the results are compared with those of two well-known indices – MSEBI and CDF. To show the capability and accuracy of the proposed index, the damages with low severity at various locations of the structures containing the elements near the supports were investigated. The results under noisy conditions are investigated by considering 3% and 5% noise on modal data. The results show a high level of accuracy of the proposed index for identifying the location of the damaged elements in beams.

In this work, continuous third-order sliding mode controllers are presented to control a five degrees-of-freedom (5-DOF) exoskeleton robot. This latter is used in physiotherapy rehabilitation of upper extremities. The aspiration is to assist the movements of patients with severe motor limitations. The control objective is then to design adept controllers to follow desired trajectories smoothly and precisely. Accordingly, it is proposed, in this work, a class of homogeneous algorithms of sliding modes having finite-time convergence properties of the states. They provide continuous control signals and are robust regardless of non-modeled dynamics, uncertainties and external disturbances. A comparative study with a robust finite-time sliding mode controller proposed in literature is performed. Simulations are accomplished to investigate the efficacy of these algorithms and the obtained results are analyzed.

The article describes motion planning of an underwater redundant manipulator with revolute joints moving in a plane under gravity and in the presence of obstacles. The proposed motion planning algorithm is based on minimization of the total energy in overcoming the hydrodynamic as well as dynamic forces acting on the manipulator while moving underwater and at the same time, avoiding both singularities and obstacle. The obstacle is considered as a point object. A recursive Lagrangian dynamics algorithm is formulated for the planar geometry to evaluate joint torques during the motion of serial link redundant manipulator fully submerged underwater. In turn the energy consumed in following a task trajectory is computed. The presence of redundancy in joint space of the manipulator facilitates selecting the optimal sequence of configurations as well as the required joint motion rates with minimum energy consumed among all possible configurations and rates. The effectiveness of the proposed motion planning algorithm is shown by applying it on a 3 degrees-of-freedom planar redundant manipulator fully submerged underwater and avoiding a point obstacle. The results establish that energy spent against overcoming loading resulted from hydrodynamic interactions majorly decides the optimal trajectory to follow in accomplishing an underwater task.

Optimization of cooling systems is of major importance due to the economy of cooling water and energy in thermal installations in the industry. The hydrodynamic study of the film is a prerequisite for the study of the intensity of the heat transfer during the cooling of a horizontal plate by a liquid film. This experimental work made it possible to quantify the hydrodynamic parameters by a new approach, a relation linking the thickness of the film to the velocity was found as a function of the geometrical and hydrodynamic characteristics of the sprayer.
A new statistical approach has been developed for the measurement of the velocity, the liquid fluid arriving at the edge of the plate and having velocity V is spilled out like a projectile. The recovering of the liquid in tubes allowed us to quantify flow rates for different heights positions relative to the plate, statistical processing permitted us to assess the probable velocity with a margin of error.

This study aims to optimize the 2-cylinder in-line reciprocating compressor crankshaft. As the crankshaft is considered the "bulkiest" component of the reciprocating compressor, its weight reduction is the focus of current research for improved performance and lower cost. Therefore, achieving a lightweight crankshaft without compromising the mechanical properties is the core objective of this study. Computational analysis for the crankshaft design optimization was performed in the following steps: kinematic analysis, static analysis, fatigue analysis, topology analysis, and dynamic modal analysis. Material retention by employing topology optimization resulted in a significant amount of weight reduction. A weight reduction of approximately 13% of the original crankshaft was achieved. At the same time, design optimization results demonstrate improvement in the mechanical properties due to better stress concentration and distribution on the crankshaft. In addition, material retention would also contribute to the material cost reduction of the crankshaft. The exact 3D model of the optimized crankshaft with complete design features is the main outcome of this research. The optimization and stress analysis methodology developed in this study can be used in broader fields such as reciprocating compressors/engines, structures, piping, and aerospace industries.

Considering the importance of gear systems as one of the important vibration and noise sources in power transmission systems, an active control for suppressing gear vibration is presented in this paper. A gear bearing model is developed and used to design an active control gear-bearing system. Two possible configurations of control system are designed based on active bearing and active gear-shaft torsional coupling to control and reduce the disturbance affecting system components. The controller for computing the actuation force is designed by using the H-infinity control approach. Simulation results indicate that the desired controller can efficiently be used for vibration control of gear bearing systems.

About the Journal
Archive of Mechanical Engineering is an international journal publishing works of wide significance, originality and relevance in most branches of mechanical engineering. The journal is peer-reviewed and is published both in electronic and printed form. Archive of Mechanical Engineering publishes original papers which have not been previously published in other journal, and are not being prepared for publication elsewhere. The publisher will not be held legally responsible should there be any claims for compensation. The journal accepts papers in English.

Archive of Mechanical Engineering is an Open Access journal. The journal does not have article processing charges (APCs) nor article submission charges.

Outline of procedures
  • To ensure that high scientific standards are met, the editorial office of Archive of Mechanical Engineering implements anti-ghost writing and guest authorship policy. Ghostwriting and guest authorship are indication of scientific dishonesty and all cases will be exposed: editorial office will inform adequate institutions (employers, scientific societies, scientific editors associations, etc.).
  • To maintain high quality of published papers, the editorial office of Archive of Mechanical Engineering applies reviewing procedure. Each manuscript undergoes crosscheck plagiarism screening. Each manuscript is reviewed by at least two independent reviewers.
  • Before publication of the paper, authors are obliged to send scanned copies of the signed originals of the declaration concerning ghostwriting, guest authorship and authors contribution and of the Open Access license.
Submission of manuscripts

The manuscripts must be written in one of the following formats:
  • TeX, LaTeX, AMSTeX, AMSLaTeX (recommended),
  • MS Word, either as standard DOCUMENT (.doc, .docx) or RICH TEXT FORMAT (.rtf).
All submissions to the AME should be made electronically via Editorial System – an online submission and peer review system at First-time users must create an Author’s account to obtain a user ID and password required to enter the system. All manuscripts receive individual identification codes that should be used in any correspondence with regard to the publication process. For the authors already registered in Editorial System it is enough to enter their username and password to log in as an author. The corresponding author should be identified while submitting a paper – personal e-mail address and postal address of the corresponding author are required. Please note that the manuscript should be prepared using our LaTeX or Word template and uploaded as a PDF file.

If you experience difficulties with the manuscript submission website, please contact the Assistant to the Editor of the AME (

All authors of the manuscript are responsible for its content; they must have agreed to its publication and have given the corresponding author the authority to act on their behalf in all matters pertaining to publication. The corresponding author is responsible for informing the co-authors of the manuscript status throughout the submission, review, and production process.

Length and arrangement

Papers (including tables and figures) should not exceed in length 25 pages of size 12.6 cm x 19.5 cm (printing area) with a font size of 11 pt. For manuscript preparation, the Authors should use the templates for Word or LaTeX available at the journal webpage. Please notice that the final layout of the article will be prepared by the journal's technical staff in LaTeX. Articles should be organized into the following sections:
  • List of keywords (separated by commas),
  • Full Name(s) of Author(s), Affiliation(s), Corresponding Author e-mail address,
  • Title,
  • Abstract,
  • Main text,
  • Appendix,
  • Acknowledgments (if applicable),
  • References.
Affiliations should include department, university, city and country. ORCID identifiers of all Authors should be added.
We suggest the title should be as short as possible but still informative.

An abstract should accompany every article. It should be a brief summary of significant results of the paper and give concise information about the content of the core idea of the paper. It should be informative and not only present the general scope of the paper, but also indicate the main results and conclusions. An abstract should not exceed 200 words.

Please follow the general rules for writing the main text of the paper:
  • use simple and declarative sentences, avoid long sentences, in which the meaning may be lost by complicated construction,
  • divide the main text into sections and subsections (if needed the subsections may be divided into paragraphs),
  • be concise, avoid idle words,
  • make your argumentation complete; use commonly understood terms; define all nonstandard symbols and abbreviations when you introduce them;
  • explain all acronyms and abbreviations when they first appear in the text;
  • use all units consistently throughout the article;
  • be self-critical as you review your drafts.
The authors are advised to use the SI system of units.


You may use line diagrams and photographs to illustrate theses from your text. The figures should be clear, easy to read and of good quality (300 dpi). The figures are preferred in a vector format (bitmap formats are acceptable, but not recommended). The size of the figures should be adequate to their contents. Use 8-9pt font size of the text within the figures.

You should use tables only to improve conciseness or where the information cannot be given satisfactorily in other ways. Tables should be numbered consecutively and referred to within the text by numbers. Each table should have an explanatory caption which should be as concise as possible. The figures and tables should be inserted in the text file, where they are mentioned.

Displayed equations should be numbered consecutively using Arabic numbers in parentheses. They should be centered, leaving a small space above and below to separate it from the surrounding text.


We encourage authors to restrict the use of footnotes. Information concerning research grant support should appear in a separate Acknowledgements section at the end of the paper. Acknowledgements of the assistance of colleagues or similar notes of appreciation should also appear in the Acknowledgements section.

References should be numbered and listed in the order that they appear in the text. References indicated by numerals in square brackets should complete the paper in the following style:

English language

Archive of Mechanical Engineering is published in English. Make sure that your manuscript is clearly and grammatically written. The content should be understandable and should not cause any confusion to the readers, including the reviewers. After accepting the manuscript for a publication in the AME, we offer a free language check service, for correcting small language mistakes.

Submission of Revised Articles

When revision of a manuscript is requested, authors are expected to deliver the revised version of the manuscript as soon as possible. The manuscript should be uploaded directly to the Editorial System as an answer to the Editor's decision, and not as a new manuscript. If it is the 1st revision, the authors are expected to return revised manuscript within 60 days; if it is the 2nd revision, the authors are expected to return revised manuscript within 14 days. Additional time for resubmission must be requested in advance. If the above mentioned deadlines are not met, the manuscript may be treated as a new submission.

Outline of the Production Process

Once an article has been accepted for publication, the manuscript is transferred into our production system to be language-edited and formatted. Language/technical editors reserve the privilege of editing manuscripts to conform with the stylistic conventions of the journal. Once the article has been typeset, PDF proofs are generated so that authors can approve all editing and layout.


Proofreading should be carried out once a final draft has been produced. Since the proofreading stage is the last opportunity to correct the article to be published, the authors are requested to make every effort to check for errors in their proofs before the paper is posted online. Authors may be asked to address remarks and queries from the language and/or technical editors. Queries are written only to request necessary information or clarification of an unclear passage. Please note that language/technical editors do not query at every instance where a change has been made. It is the author's responsibility to read the entire text, tables, and figure legends, not just items queried. Major alterations made will always be submitted to the authors for approval. The corresponding author receives e-mail notification when a PDF is available and should return the comments within 3 days of receipt. Comments must be uploaded to Editorial System.


The Editorial Board of the Archive of Mechanical Engineering (AME) sincerely expresses gratitude to the following individuals who devoted their time to review papers submitted to the journal. Particularly, we express our gratitude to those who reviewed papers several times.
