考虑铰链间隙、构件柔性的动力学仿真分析

s the development of modern science and technology ,more and more high requests to the performance of modern machine systems, and urgent demand the accurate estimate of muti-body machine system dynamic behavior. Joint clearances and member flexibility are considered two main factors to accurately predict the dynamic performance. This article recur to the software of ADAMS using a non-linear elastic-damper model of the clearance connections.The dynamics of a slider-crank structure was simulated with either no-clearance joints,clearance connections or flexible members.The simulation results show that the dynamic performance of the structure is greatly influenced by the clearances and the member flexibility.
