摘　　要：针对多芯护套线剥线机双头滚珠丝杠设计是否疲劳失效的问题,建立其数学模型,利用有限元软件对丝杠进行静力学和模态分析,获得丝杠的固有频率和振型等参数,得到刀架本身的动态性能满足设计需求,为护套线剥线机结构系统的振动特性分析、振动故障诊断和预报以及结构动力特性的优化设计提供依据。In view of the problem of fatigue failure in the design of double head ball screw of multi-core sheath wire stripping machine,this paper establishes its mathematical model,does static and modal analysis on the lead screw by finite element software,obtains the natural frequency,vibration mode and other parameters of the lead screw,and gets the dynamic performance design requirements of the tool holder itself,to provides the basis for the vibration characteristic analysis,vibration fault diagnosis and prediction of the structure system of the sheath wire stripper and the optimization design of the dynamic characteristics of the structure.
