    摘要:

    采用有限元法求解壁面定律和Reynolds方程，對(duì)水潤(rùn)滑高速動(dòng)靜壓滑動(dòng)軸承進(jìn)行了數(shù)值模擬分析,。研究紊流狀態(tài)水介質(zhì)潤(rùn)滑條件下的動(dòng)靜壓軸承三維壓力分布,、溫度場(chǎng)分布及動(dòng)特性系數(shù)，分析高速高壓水潤(rùn)滑條件下的動(dòng)靜壓軸承與油潤(rùn)滑條件下的動(dòng)靜壓軸承不同的液腔壓力分布,、溫度分布等特性,。

    Abstract:

    Three dimensional pressure distribution and temperature field of the bear in water lubrication and its difference between the bear in oil lubrication were analyzed in numerical simulating through solving the law-of-the-wall and Reynolds equation with finite elements method (FEM), and the changes of lubricant viscosity with temperature were taken into account. The result showed that under high speed condition, pressure distribution and temperature field of the bear are different from those with oil lubrication and also could control the temperature of bear effectively with water lubrication.
