Abstract

This paper is a case study conducted to present an approach to the process of designing

new products using virtual prototyping. During the first stage of research a digital geometric

model of the vehicle was created. Secondly it underwent a series of tests utilising the

multibody system method in order to determine the forces and displacements in selected

construction nodes of the vehicle during its movement on an uneven surface. In consequence

the most dangerous case of loads was identified. The obtained results were used to conduct

detailed strength testing of the bicycle frame and changes its geometry. For the purposes

of this case study two FEA software environments (Inventor and SolidWorks) were used. It

has been confirmed that using method allows to implement the process of creating a new

product more effectively as well as to assess the influence of the conditions of its usage more

efficiently. It was stated that using of different software environments increases the complexity

of the technical process of production preparation but at the same time increases the

certainty of prototype testing. The presented example of simulation calculations made for

the bicycle can be considered as a useful method for calculating other prototypes with high

complexity of construction due to its systematized character of chosen conditions and testing

procedure. It allows to verify the correctness of construction, functionality and perform

many analyses, which can contribute to the elimination of possible errors as early as at the

construction stage.

Abstract

This paper presents a design of a tracked in-pipe inspection mobile robot with an adaptive drive positioning system. The robot is intended to operate in circular and rectangular pipes and ducts, oriented horizontally and vertically. The paper covers a design process of a virtual prototype, focusing on track adaptation to work environment. A mathematical description of a kinematic model of the robot is presented. Operation of the prototype in pipes with a cross-section greater than 210 mm is described. Laboratory tests that validate the design and enable determination of energy consumption of the robot are presented.
