采用有限元法分析计算了上瓦开周向槽椭圆轴承的静动特性；采用复合形法，以单位承载量下的功耗最小为目标函数，对该种轴承进行了优化设计。
The static and dynamic characteristics of the oval bearing with the upper wavy groove are calculated and analyzed by the finite element method. The complex shape method is adopted to optimize the design of the bearing with the minimum power consumption per unit load as the objective function.
