    Numerical Simulation for Metal Surface Wear Based on Theory of Elastic-Plastic Contact

    • 摘要: 为了对金属表面磨损的过程进行计算,采用自相关函数模拟构建了磨损表面的微观形貌,应用有关弹塑性接触理论,构建了一种能够对金属表面滑动过程磨损进行数值模拟计算的方法,通过与有关文献的测试数据进行比较,证明了所构建计算模型的可信性。在此基础上,以Q235A、45#磨损表面为研究对象,数值模拟研究了滑动磨损过程中随磨损次数的增加,磨损表面表面形貌、接触面的弹塑性区域、磨损量、表面间距、表面粗糙度等性能的变化规律,绘制了相关曲线,并对这些曲线进行了分析讨论。本文的研究为对金属表面的磨损过程进行理论计算提供了一种有益的新思路。

       

      Abstract: To predict contact and wear of metal surface microscopically,a metal surface wear simulation method based on the theory of elastic-plastic contact is proposed and established in this paper.The numerical simulation model is verified by comparing the calculation results and experimental results.Micro-surface morphology of Q235A and 45# are simulated by using the adaptive correlation function.The numerical amount of wear is calculated under different external loads.The wear process and properties of metal surface are analyzed with considering the relationship among the wear,toughness and the distance of the wear surface and times.The present study provides a new way for the theoretical calculation of the wear process for the metal surface.
