摘要
本文提出了一种偏导数法求解动压滑动轴承油膜动特性系数的改进方法——矩阵法。用偏导数法一旦求得四个关于的积分方程，它们的矩阵表达式便可直接得到，积分后，可解出八个油膜动特性系数。用这种方法比其他方法节省１／２～２／３的计算时间。
In this paper,the matrix methed, an improved partial derivative method for calculating the oil-film dynamic coefficients of hydrodynamic Journal bearings is presented. Once the integral equations of thefour functions,i.e are got with partial derivative method, their matrix ex-pressions can be obtained immediately We can get the eight oil -film bynamic coefficents by integratingthem over the film domain and it takes 2 3 times less computer time than other methods.
