应用动网格对阀片运动规律的瞬态数值模拟

Transient Numerical Simulation of the Movement Regulation of Valve by Applying Dynamic Grid

影响压缩机阀片运动的因素较多,阀片的运动在这些因素的作用下变得非常复杂。从数值模拟的角度对阀片的运动规律进行瞬态模拟,可使阀片的运动过程更直观。在数值模拟的过程中,主要讨论了弹簧弹性系数、工质密度和阀片质量对阀片运动规律的影响,并得出相关结论。该方法对气阀的设计有一定的借鉴意义。

There are a lot of factors affecting compressor valve movement,thus the valve movement become very complicated under the effect of these factors.The transient simulation for the valve movement regulation is carried out from the point of numerical simulation,which can be more intuitive of the movement process.In the process of numerical simulation,the influences of spring elastic coefficient,working fluid mass density and valves quality on the valve movement regulation are mainly discussed and the relevant conclusions are obtained.This method has some reference for the design of valve.
