A Friction-Dissipation Based Method for Quantity Model and Prediction of Graphite/WC-Ni Wear under Dry Sliding

  • 摘要: 从摩擦耗散的角度研究干摩擦下石墨/WC-Ni配副磨损与摩擦副摩擦耗散能量之间的规律,获得了石墨磨损与配副摩擦耗散功率之间的关系,结果表明石墨干摩擦下的磨损率与配副的摩擦耗散功率呈显著的线性关系. 单一和组合工况磨损预测试验表明:石墨磨损模型能够准确地预测不同工况下石墨的磨损量,预测结果和实际测量结果符合. 干摩擦下石墨磨损率与摩擦耗散功率之间的定量关系,物理意义明确,使用方便,结果可靠,研究结果具有重要的理论和工程应用价值.

     

    Abstract: In the present work, a linear model for assessing the wear of graphite sliding against WC-Ni under dry condition was developed. This model described the relationship between the wear rate of graphite with the friction dissipation of the graphite/WC-Ni. This model was utilized to predict the graphite wear of both single and combined working conditions, the predict results were in good agreement with the measured results. The model had a clear physical meaning, and was concise, easy use and reliable. The quantitative model for assessing and predicting the wear of tribo-pair was not only theoretical but also practical significant.
