| 摘 要： | 针对往复泵外载荷作用复杂、缸体与阀套接触面上容易出现裂纹而失效的问题,依据往复泵工作原理、流体力学基本理论和接触问题数值方法,建立了高压往复泵缸体-阀座-阀套系统的接触模型.在考虑压力脉动、流量脉动、交变载荷和进、出口阀门开启关闭的撞击等多种因素的综合作用下,建立了高压往复泵缸体-阀座-阀套系统的有限元模型,对整个系统的接触状态进行了分析,得到缸体系统的应力分布、接触状态和接触面的接触应力分布情况及薄弱部位的位置.

| Abstract: | The cylinder bodies of reciprocating pumps easily fail from cracks due to complex external loads.Based on the working principle of reciprocating pumps,hydrodynamics,and a numerical method for surface-to-surface contact problems,a contact model involving a cylinder body,a valve base,and a valve pocket is established.Considering pressure fluctuation,flow pulsation,alternate loads,and the impact of the inlet and outlet valves,a finite element model for the complete system is established.Using this model,the co... |
