摘　　要：为解决基于并联机构中运动副存在间隙而使得激振台在高频激振的情况下运动无法传递的问题,提出了运用柔性万向节代替普通万向节的并联机构激振台。在ADMAS中建立柔性关节激振平台的虚拟样机模型,通过仿真验证并联机构柔性激振台的可行性。并对普通万向节测试其运动输出。In order to resolve the problem that kinematics pair of parallel mechanism have clearances which make vibration platform can not output motion under high frequency vibratory stress relief, presenting a idea of using flexible joint replace universal joint. Firstly,we can obtain the forward and inverse kinematic resolutions by calculation. Secondly,the virtual prototype was built through ADAMS,the simulations on kinematics and dynamic performance were carried out in ADAMS. The simulated results showed that the design parallel mechanical vibration is feasible. Finally,motion output can be tested respectively on universal joint.
