摘　　要：针对动压轴承形状设计的局限性,提出了基于泛函的动压轴承形状设计方法,利用具有表征动压轴承型线函数特征的泛函集成形式表示动压轴承膜厚方程并建立控制方程,以轴承型线的泛函系数为变量,以轴承的最大承载力为目标进行形状优化。通过实例分析,得出用新方法设计出的轴承形状摆脱了原始形状的限制,并且其优化结果优于用传统方法得到的结果。该方法为设计出新的具有最佳性能的轴承形状提供了新的思路。Because of the limitation of shape design for hydrodynamic bearings,a new method of shape design based on functions was proposed.The film thickness equation was represented in a functional integrated form,which can express functional characters of profiles for hydrodynamic bearings,and control equations were built.The shape of bearings was optimized when the functional coefficients of bearings profiles were taken as design variables and the maximum carry-load capacity of bearings was taken as the optimizati...
