摘　　要：本文发现和改正了目前国内外所沿用的非稳态弹流润滑油膜的Holland计算方法中的一些错误,并补充了dh/dt<0时的计算公式。凸轮-挺柱弹流润滑问题的计算结果表明,本方法较为合理,并否定了基于稳态计算结果所得的一个结论。In this paper some mistakes of Holland method for calculating unsteady elasto-hydrodynamic lubrication film are found and corrected and the formula for dh/dt<Ocase is added. The computational results for elastohydrodynamic lubrication pro-blem of cam-tappet pair show that our method is reasonable. An conclusion aboutcam lubrication based on the results from steady film theory is refuted.
