摘　　要：并联机构的刚度是衡量机构承受载荷能力的重要参数其刚度特性研究是国内外的一个重要的研究课题。在Pro-E中建立3-SPS/S的参数化实体模型,将其导入Ansys-Workbench中进行静力学分析,得到其静态刚度性能。再将3SPS/S实体模型导入RecurDyn中进行运动学分析,用以得到三个杆的位移变化曲线,同时也证明了其运动形式的可行性。结合以上位移曲线在Ansys-Workbench中对并联机构3SPS/S进行瞬态动力学分析,得到其在动态过程中刚度性能。与前面的静态分析相结合,更为全面的了解并联机构3SPS/S的性能,从而为并联机构的设计、校核提供一种新思路。The parallel mechanism stiffness is an important parameter to measure the institutions to withstand the load capacity and stiffness characteristics,which is an important research topic domestic and foreign.3-SPS/S parametric model is established in Pro-E.It is imported in Ansys-workbench and done with analysis of the stiffness performance.Then,3-SPS/S parametric model is imported in Recurdyn and carried out analysis for the three rod displacement curve.The solid model is combined with the previous driver displacement parallel institutions to do the transient dynamics analysis for stiffness performance and to demonstrate the feasibility of its movement in its form.Combined with the front of the static analysis and a more comprehensive understanding of the parallel mechanism 3-SPS/S performance,it provides a new idea for the design of parallel institutions and checking.
