Analysis and Research on Flexible Bar of Parallel Mechanism

Qian Taili;Yu Dayong;School of Mechanical Engineering, University of Shanghai for Science and Technology;  
In order to reduce the influence of the flexible deformation and vibration of the parallel mechanism on the system's motion accuracy, this paper analyzes the three-dimensional modeling of the rod with ADAMS modal by Pro/E software, and studies dynamic characteristics of the model. The results show that the time required for restoring of steady state is different when the force applied on these rods is different, and the maximum stress occurs at the abrupt change of cross-sectional area of the rods, which can well provide designers with powerful theories. Based on the analysis of the flexible members of the parallel mechanism, it laid the foundation for further study on the dynamic characteristics and error analysis of the parallel mechanism.
