| 摘 要： | 基于M-B分形接触模型,通过构建接触系数建立了考虑两粗糙面分形特征的接触模型。分析结果表明,修正模型能较好地与实验数据相吻合,并适用于更大的载荷,修正模型综合考虑两粗糙面的特性,其计算结果与实际接触情况更相符,为摩擦磨损预测、磨粒分析以及不同粗糙度表面的接触分析提供了参考。

| Abstract: | Based on the M-B fractal contact model,a contact model was built accounted for the fractal characteristics of two rough surfaces by constructing the contact coefficient.The analysis results show that the correction model has a good agreement with experimental date,and it is applicable to larger load.The correction model combines the characteristics of two rough surfaces, which fits better in with actual contact conditions,and it can provide reference to friction prediction, wear prediction, wear particle analysis and different roughness surface analyses. |
