阻尼槽型連續(xù)供油配流副潤滑機理的數(shù)值模擬

建立了阻尼槽型連續(xù)供油配流副油膜形成的數(shù)學(xué)模型。該數(shù)學(xué)模型用于描述配流副中油膜的運動變化規(guī)律和工作介質(zhì)在阻尼槽、通油槽中的壓力、流量特性及分布規(guī)律。在數(shù)學(xué)模型中考慮了配流副高、低壓對油膜形成和變化產(chǎn)生的影響。通過該數(shù)學(xué)模型可以得出壓力、溫度對配流副油膜厚度、泄漏流量等潤滑特性參數(shù)的影響規(guī)律。對不同工況下配流副油膜的形成進行仿真分析，結(jié)果表明在其他工況不變時，油膜厚度隨壓力和溫度的增加而減小，配流副泄漏流量隨壓力和溫度的增加而增大。
The mathematic model of the lubricating film formation is established to illustrate the variation of the lubricating film thickness and the pressure-flow characteristics in the damping groove and pressure groove of port plate/cylinder block. The influence of the high pressure and low pressure on the film formation is considered in the mathematic model. The influence regularity of working pressure and temperature on the lubrication parameters can be acquired in the mathematic model. The formation of the lubricating film thickness is simulated in different working conditions. The simulation results show when other working condition is invariable, the film thickness will decrease with the pressure and temperature increasing, and the leakage of the fluid in friction pair will increase with the pressure and temperature increasing.
