摘　　要：间隙会造成轧机主传动系统特性变差,间隙大小对系统的影响如何是生产企业所关注的。基于数值模拟与有限元分析方法,研究含多间隙的成品初轧机主传动系统,因间隙大小的不同而引起系统动态特性的变化。利用Matlab数值仿真和Ansys有限元计算,分别得出不同间隙对系统动态响应与应力变化的不同影响。两种方法相互验证与补充为轧机生产实践提供理论参考。The gap can result in the characteristics of the main drive system of the mill become bad,the influence of the gap size on the system is the concern of enterprises.This paper is based on numerical simulation and finite element analysis,to study the main drive system of the initial mill with multiple gaps,its dynamic characteristics are changed due to the difference of gap size.a The difference of dynamic response and stress change of the system is obtained by using MATLAB numerical simulation and ANSYS finite element calculation.This two methods verify and supplement each other to provide theoretical reference for mill production practice.
