摘　　要：用矩阵分析法求解动态Ｒｅｙｎｏｌｄｓ方程，得到了轴承油膜反力分量ｆｘ、ｆｙ的矩阵表达式，并将ｆｘ、ｆｙ分别对位移扰动ｘｒ、ｙｒ及速度扰动ｕｒ、ｖｒ求导，进而得到动特性系数的矩阵形式。这种矩阵分析法，比著名的偏导数法可少解二次Ｒｅｙｎｏｌｄｓ方程。Matrix expressions for calculating foring film reaction force components fx、fy are presented by solving the Reynoldsequation with the matrix method, and the dynamic coefficients can be obtained in matrix form by differentiating fx, fy withrespect to the perturbations of displacement xr, yr and velocity components ur, vr respectively. With this method, the Reynoldsequation would be solved two times less than that with the famous partial derivative method.
