摘　　要：航空发动机叶片因复杂的曲面结构,在精加工阶段仍靠传统手工打磨抛光。为提高航空叶片打磨效率,设计一套专门针对压气机叶片的混联式砂带磨削装置。对混联磨削装置中的3-RPS并联机构进行运动学位置正反解分析后,建立并联机构的虚拟样机并导入ADAMS软件中进行仿真验证。结合蒙特卡洛法和极限边界数值搜索法理论,应用MATLAB求得并联机构和混联装置的工作空间,结果表明混联打磨装置满足压气机叶片实际打磨工作空间要求,为后续平台搭建提供参考。Due to the complex curved structure of aero engine blades,traditional manual grinding and polishing are still used in the finishing stage.In order to improve the grinding efficiency of blade,a set of hybrid belt grinding device specially designed for compressor blades was designed.The 3-RPS parallel mechanism in the hybrid grinding device was analyzed for forward and reverse kinematics,and a virtual prototype was built and imported into the ADAMS software for simulation verification.Combining Monte Carlo method and limit boundary numerical search method to obtain the working space of the parallel mechanism and the hybrid device in MATLAB.The results show that the hybrid grinding device meets the requirements of the grinding space of the compressor blade,and provides a reference for the subsequent platform construction.
