摘要
往复泵泵阀弹簧是泵阀中的一个重要零件,寿命将影响往复泵的使用。通过利用软件Matlab对泵阀的运动特性进行模拟仿真,得出了泵阀(弹簧)的运动规律。在有限元分析软件Ansys中,考虑随时间变化的位移载荷,对弹簧进行静态非线性结构下的应力分析,分析了动态的应力分布情况及弹簧失效原因,并针对弹簧失效原因提出改进,提高了弹簧的使用寿命。
For the reciprocating pump valve,the spring is very important,its life will affect the use of the reciprocating pump.This paper used software Matlab to imitate the motion characteristics of the pump valve,obtained the motion of the pump valve(spring).In finite element analysis software Ansys,conside the displacement load changes over time,analyze the spring with the static nonlinear structural stress analysis,obtained the dynamic stress distribution and the failure reasons of spring.Then for the failure reasons of spring to improve,improved the service life of spring.
