摘要
为解决传统激振台不能实现多维同时振动的问题,基于并联机构组成原理,设计了用于中小型试验件振动测试的并联机构激振台,分析了3-PUU型三维纯平移并联机构的运动特性,通过计算得出了正、逆解析解。在ADAMS中建立该并联机构的虚拟样机模型,并通过仿真验证了并联机构激振台的可行性。
According to the structural theory of parallel robot mechanism, a 3 - DOF translational parallel mechanism with 3 - PUU joint structure was investigated by the single-opened-chain unit approach. Firstly, the structural characteristics analysis for the parallel mechanism was elaborated, including mobility analysis, motion output analysis and structure complexity analysis. The forward and inverse kinematics resolutions were obtained respectively. Secondly, the virtual prototype was built through Mechanical/Pro with Pro/E and ADAMS. Finally, the simulations on kinematics and dynamic performance were carried out in ADAMS. The simulated results showed that the design parallel mechanical vibration platform is feasible.
