摘要
提出了一种快速求解８个轴承动特性的系数有限元法。该方法不仅比以往的有限元法计算速度快，而且与其他方法具有同样的计算精度。
A finite element method is presented for computing the oil film dynamic coefficients of hydrodynamic journal bearings.Once the integral equations of the four functions,p/x c,p/y c,p/u c,p/v c ,are gotten,their matrix expressions can be obtained immediately.Jntegrating them over the film domain,we can get the eight oil film dynamic coefficients.Then it is possible to solve the Reynolds equation only once.
