在理论计算的基础上,采用UG软件建立减振弹簧模型,结合理论值对弹簧模型进行有限元分析,从分析结果可知：模型刚度有限元分析结果与理论计算值基本一致；对弹簧的疲劳强度分析可知,理论疲劳安全系数与有限元分析结果基本相等,模型的强度足够；弹簧静强度安全系数为1.42,静强度合格；弹簧最小固有频率大于振动机振动频率,故弹簧不会发生共振。

The model of damping spring is built by UG software on the basis of theoretical calculation, and the finite element analysis of damping spring is processed, in combination with the theoretical values. In analysis result, it can be found out that the theoretical value of the model stiffness is the same with that of the finite element analysis;the theoretical fatigue safety factor is basical y identi-cal with that of the finite element analysis, and the model strength is enough;the static strength safety factor of the spring is 1.42, which meets the requirement of the static strength; the smal est natural frequency of the damping spring is bigger than the vibration frequency of the vibrating machine, so the spring does not resonate at a certain frequency.
