【摘要】 为了实现动态机械设计，对预测摩擦副表面粗糙度的变化进行了研究．在三体磨损状态下，建立了摩擦副表面轮廓高度概率分布密度的预测模型．算例表明：表面形貌的变化不仅与磨程而且与所考察的轮廓线沿２ 个表面相对运动方向的位置有关，其预测结果与实验结果相符合更多还原

【Abstract】 A mathematical model is presented for predicting the probability distribution density functions of profile height and roughness of the interacting surface subject to three body abrasive wear. The analytical and experimental results show that the roughness varies not only with wear distance but also the position of the profile on the surface.更多还原
