摘要
首先分析了平面两自由度全柔顺并联机构的微运动学;然后在此基础上建立该机构的拓扑优化模型,运用OC算法对所建立的模型进行求解;最后运用有限元软件对所建立的三维模型进行仿真。得出通过拓扑优化得到的平面两自由度全柔顺并联机构可实现x和y两个方向的微运动,且与同构型的传统并联机构运动相似,验证了该方法的有效性。
This article has analyzed the differential kinematics of full compliant parallel mechanism under plane two degreeof-freedom first. Then topology optimization models were established based on this theory. The models were solved using the OC algorithm. Three-dimensional models were performed simulations using finite element software eventually. The plane two degreeof-freedom full compliant parallel mechanism could be achieved in both x and y direction movements according to the topology optimization. This movement was similar with the same configured traditional parallel mechanism, which verified the effectiveness of this method.
