摘要
介绍柱塞泵缸体镶铜衬套的结构特点,并将其简化为厚壁圆筒模型进行装配过盈量的理论计算。在此基础上通过ABAQUS有限元分析得出了不同过盈量下的各种应力云图,并针对衬套外圆加环槽和不加环槽两种结构对装配结合力的影响进行了有限元对比分析,剖析了在衬套外圆加工环槽的作用,为柱塞泵缸体衬套的结构设计及过盈量计算提供了参考。
The structure characteristics of the piston pump cylinder copper bushing were introduced,which was simplified as the thick wall cylinder model for the theoretical calculation of the assembly over surplus quantity. On this basis,various stress nephograms were obtained by ABAQUS finite element analysis （FEA）under different over surplus quantities. Moreover aiming at impacting of the bushing cylinder with ring groove and without ring groove on assembly binding force,the FEA comparison was carried out,and the roles of the ring groove were analyzed. It provides reference for the structure design and over surplus quantity calculation of axial piston pump cylinder copper sleeve.
