摘　　要：设计了一种以柔性铰链为运动副,磁致伸缩作动器为驱动支杆的并联微动机构.运用三维设计软件SolidWorks建立部件和整体模型,并运用SolidWorks内嵌的有限元分析软件COSMOSXpress对柔性铰链进行有限元分析,优化其结构和尺寸.采用SolidWorks的另一插件COSMOSWorks对驱动支杆进行固有频率分析,并对整体机构进行刚度分析和安全校核.结果证明COSMOS可以指导设计改进,提高设计的准确性和可靠性.A type of parallel micromanipulator with flexible hinges as the motion pair and magnetostrictive actuator as the driving rod is designed. The parts and whole model are established by 3D Designing Software SolidWorks. Flexible hinges are analyzed by Finite Element Analysis Software COSMOSX press, which is embedded in SolidWorks, to optimize the structure and size of hinges. The natural frequency of driving rod and stiffness and safety of the whole mechanism are analyzed by another add-in COSMOS Works. The result shows that COMOS helps to improve the accuracy and reliability of the design.
