摘　　要：液压联轴器在高压油的作用下,胀紧套与保持套抱紧,利用摩擦力传递扭矩。某轧机用液压联轴器使用一段时间后出现裂纹,为了分析联轴器失效原因,进行了仿真分析研究。本文介绍了液压联轴器胀紧套弹性、弹塑性以及塑性发展趋势仿真研究的详细过程及成果,为解决类似结构设计分析及评判问题提供了一种思路。Under the action of high-pressure oil,the hydraulic coupling holds the expansion sleeve and the holding sleeve tightly,and uses the friction force to transfer the torque.In order to analyze the reasons for the coupling failure,the simulation analysis was carried out for the hydraulic coupling of a rolling mill which appeared crack after being used for a period of time.In this paper,the detailed process and results of the simulation research on elastic,elastic-plastic and plastic development trend of expansion sleeve of hydraulic coupling are introduced.It provides a way of thinking for the analysis and evaluation of similar structure design.
