Strength analysis of parallel robot components in PLM Siemens NX 8.5 program

This article presents a series of numerical analyses in order to identify the states of stress in elements, which arise during the operation of the mechanism. The object of the research was parallel robot, which is the basis for the prototype of a driving simulator. To conduct the dynamic analysis was used the Motion Simulation module and the RecurDyn solver. In this module were created the joints which occur in the mechanism of a parallel robot. Next dynamic analyzes were performed to determine the maximal forces that will applied to the analyzed elements. It was also analyzed the platform motion during the simulation a collision of a car with a wall. In the next step, basing on the results obtained in the dynamic analysis, were performed the strength analyzes in the Advanced Simulation module. For calculation the NX Nastran solver was used..
