摘　　要：活塞杆是压缩机的重要零部件之一,同时又是活塞的导向零部件之一,活塞杆的变形程度直接影响到气缸的密封性和活塞与汽缸之间的磨损程度。文中针对立式压缩机活塞杆,利用Creo进行建模,然后利用Workbench有限元计算方法,对活塞杆进行模态分析,并进行谐响应分析,得到活塞杆的最大变形量。分析结果表明,采用实心杆件设计可以有效减小活塞杆的变形量,为活塞杆的进一步优化设计提供理论基础。Piston rod is one of the important components of the compressor, and it is one of the piston-oriented components.The deformation of the piston rod directly affects the cylinder seal and the degree of wear between the piston and the cylinder.This paper builds model of the working rod in vertical compressor using Creo, and then the static deformation of the piston rod is analyzed using Workbench finite element method.The maximum deformation of the piston rod is obtained by harmonic response analysis. The results show that the design of the solid rod can effectively reduce the deformation of the piston rod, and provides the theoretical basis for the further optimization of the piston rod.
