| 摘 要： | 本对发动机的滑动轴承进行了计算，求解了滑动轴承的雷诺方程，粘度方程，密度方程与载荷方程，得到了压力分布与油膜厚度分布，进而通过接触力学分析得到轴承衬内的应力分布。应力分布是影响材料的塑性变形，并对分析滑动轴承的胶合失效有实际意义，因此建议用最大Mises应力来指导滑动轴承的设计。

| Abstract: | The performace of joumal bearing of automobile engines is analyzed in this paper.The Reynolds equation, viscosity equation, density equation and load equation are solved with a finite differential method.The hydrodynamic pressure distribution and film shape are obtained, and the three-dimensional Mises stress field is calculated based on the above pressure distribution.The maximum Mises stess is significantly related with the seizuring failure of bearing bushes;therefore the maximum stress is proposed to be used to guide the design of journal bearings. |
