Abstract

This paper presents a kinematic and dynamic analysis and distribution of the stress for four-item planar mechanism by means of the SolidWorks software. Graphic dependence of kinematic and dynamic magnitudes of some points is given in dependence on the angle of rotation of the driving item and in dependence on the time. Distribution of the stress in the items is presented in [Pa]. In relation to the kinematic and dynamic analysis and subsequent simulation of the planar as well as spatial mechanisms, it is great solution to use SolidWorks software program. The considerable advantage of this mentioned program is based on its simplicity from the aspect of modeling and moreover, it is important to point out that utilisation of the mentioned program leads to results which are precise and accurate in the case of the numerical solution of the equations in the whole magnitude referring to motion of mechanism while the given results are obtained in the graphic form.

Highlights

The main objective of the kinematic and dynamic analysis of the four-item planar mechanism in the SolidWorks program was closely connected with the investigation of the position deviation tolerance, the convergence speed of equation solutions for the each one specified position of the planar mechanism
Using the kinematic analysis [4,5,6] and dynamic analysis and subsequent simulation [1,2,3], the main objective is connected with the determination and entering of the position domains, speed domains as well as acceleration of the individual bodies in relation to the specified input values of the angular velocity for the Corresponding author: jan.vavro.jr@fpt.tnuni.sk
The simulation [12] of operation relating to planar mechanism can be seen in the Fig. 4 for time step referring to one second while the whole simulation takes place for ten seconds

Summary

Introduction

The main objective of the kinematic and dynamic analysis of the four-item planar mechanism in the SolidWorks program was closely connected with the investigation of the position deviation tolerance, the convergence speed of equation solutions for the each one specified position of the planar mechanism. The mentioned analysis will be used for comparison of the obtained results with the results, which will be obtained by help of any other commercial software systems
