Similarity assessment between 3D models is an important problem in many fields including medicine, biology and industry. As there is no direct method to compare 3D geometries, different model representations (shape signatures) are developed to enable shape description, indexing and clustering. Even though some of those descriptors proved to achieve high classification precision, their application is often limited. In this work, a different approach to similarity assessment of 3D CAD models was presented. Instead of focusing on one specific shape signature, 45 easy-to-extract shape signatures were considered simultaneously. The vector of those features constituted an input for 3 machine learning algorithms: the random forest classifier, the support vector classifier and the fully connected neural network. The usefulness of the proposed approach was evaluated with a dataset consisting of over 1600 CAD models belonging to 9 separate classes. Different values of hyperparameters, as well as neural network configurations, were considered. Retrieval accuracy exceeding 99% was achieved on the test dataset.

Automation of earth moving machineries is a widely studied problem. This paper focusses on one of the main challenges in automation of the earth moving industry, estimation of loading torque acting on the machinery. Loading torque acting on the excavation machinery is a very significant aspect in terms of both machine and operator safety. In this study, a disturbance observer-assisted control system for the estimation of loading torque acting on a robotic backhoe during excavation process is presented. The proposed observer does not use any acceleration measurements, rather, is proposed as a function of joint velocity. Numerical simulations are performed to demonstrate the effectiveness of the proposed control scheme in tracking the reaction torques for a given dig cycle. Co-simulation experiments demonstrate robust performance and accurate tracking of the proposed control in both disturbance torque and position tracking. Further, the performance and sensitivity of the proposed control are also analyzed through the help of performance error quantifiers, the root-mean-square (RMS) values of the position and disturbance tracking errors.

A brief review of the existing autonomous underwater vehicles, their types, design, movement abilities and missions is presented. It is shown, the shape optimization design and enhancement of their efficiency is the main problem for further development of multipurpose glider technologies. A comparative study of aerodynamic performance of three different shape designs (the airfoil NACA0022 based (I), flattened ellipsoidal (II) and cigar-type (III) bodies of the same volumes) has been carried out. Geometrical modelling, meshing and computational fluid dynamics (CFD) simulations have been carried out with AnSys15.0. The pathlines and wall shear stress distributions have been computed to understand the advantages and disadvantages of each shape. The lift and drag coefficients, aerodynamic quality, power index and pitching moment have been computed. The higher efficiency of the shape I/shape II at higher/lower angles of attack (> 20o and < 20o) has been found. The shape III develops high speeds at the same angles of attack and has higher manoeuvrability at relatively low aerodynamic quality. The comparative analysis of the flow capabilities of studied autonomous undersea vehicles proposes some design improvement for increasing their energy efficiency and flow stability.

The paper presents a simulation model of the hybrid magnetic bearing dedicated to simulations of transient state. The proposed field-circuit model is composed of two components. The first part constitutes a set of ordinary differential equations that describes electrical circuits and mechanics. The second part of the simulation model consists of parameters such as magnetic forces, dynamic inductances and velocity-induced voltages obtained from the 3D finite element analysis. The MATLAB/Simulnik softwarewas used to implement the simulation model with the required control system. The proposed field-circuit model was validated by comparison of time responses with the prototype of the hybrid magnetic bearing.

An attempt is made in the current research to obtain the fundamental buckling torque and the associated buckled shape of an annular plate. The plate is subjected to a torque on its outer edge. An isotropic homogeneous plate is considered. The governing equations of the plate in polar coordinates are established with the aid of the Mindlin plate theory. Deformations and stresses of the plate prior to buckling are determined using the axisymmetric flatness conditions. Small perturbations are then applied to construct the linearised stability equations which govern the onset of buckling. To solve the highly coupled equations in terms of displacements and rotations, periodic auxiliary functions and the generalised differential quadrature method are applied. The coupled linear algebraic equations are a set of homogeneous equations dealing with the buckling state of the plate subjected to a unique torque. Benchmark results are given in tabular presentations for combinations of free, simply-supported, and clamped types of boundary conditions. It is shown that the critical buckling torque and its associated shape highly depend upon the combination of boundary conditions, radius ratio, and the thickness ratio.

In the present work, a procedure for the estimation of internal damping in a cracked rotor system is described. The internal (or rotating) damping is one of the important rotor system parameters and it contributes to the instability of the system above its critical speed. A rotor with a crack during fatigue loading has rubbing action between the two crack faces, which contributes to the internal damping. Hence, internal damping estimation also can be an indicator of the presence of a crack. A cracked rotor system with an offset disc, which incorporates the rotary and translatory of inertia and gyroscopic effect of the disc is considered. The transverse crack is modeled based on the switching crack assumption, which gives multiple harmonics excitation to the rotor system. Moreover, due to the crack asymmetry, the multiple harmonic excitations leads to the forward and backward whirls in the rotor orbit. Based on equations of motions derived in the frequency domain (full spectrum), an estimation procedure is evolved to identify the internal and external damping, the additive crack stiffness and unbalance in the rotor system. Numerically, the identification procedure is tested using noisy responses and bias errors in system parameters.

Contemporary research on mobile robotics aims at designing robots that will be able to traverse an extremely varied environment. One of the most universal modes of locomotion is the serpentine movement. A majority of modern snake-like robots use electric drives. This study presents a snake-like robot made out of McKibben muscles. Using a pneumatic cable with muscles arranged in series, it is possible to create a robot of any length, limited only by the length of the muscle cables. Because the control system and the body of the robot are separate, the robot can be used for rescue missions involving high risk of explosion of flammable substances and for missions taking place on extremely difficult terrain.

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.
