A method for simulating fretting wear using the Modified Simplex Method for a contact solution has been developed. The initial separation between two contacting bodies was used as an input to solve the contact force distribution. An average cycle pressure distribution was calculated for the stationary surface over a displacement cycle. The wear depth was calculated for each body based on the modified Archard’s wear equation using the force distributions and the gross sliding distance. The initial separation was updated and the force distribution was solved for the next iteration. Methods for optimizing computational time are presented using a combination of linear jumping and adaptive cycle jumping for the wear depths, and an interpolation weighting method for reducing the grid size. It was found that computational time can be reduced by at least 98% compared with other simulation methods, making this method a viable tool for design. Fretting wear scars and depths were simulated for a cylinder on flat in contact and were found to agree with experimental results and Finite Element modeling results from previous literature. To show the capability of the fretting wear model, three practical applications were simulated: automotive seat sliding rails, steel wire ropes for industrial applications and steam generator tubes for nuclear power stations.

已经开发了一种使用修正单纯形法模拟微动磨损的方法，用于接触解决方案。两个接触体之间的初始分离被用作求解接触力分布的输入。计算了位移循环中静止表面的平均循环压力分布。基于修正的 Archard 磨损方程，使用力分布和总滑动距离计算每个车身的磨损深度。更新初始分离并求解下一次迭代的力分布。提出了使用线性跳跃和自适应循环跳跃的组合来优化计算时间的方法，以及用于减小网格尺寸的插值加权方法。结果表明，与其他仿真方法相比，计算时间可减少至少 98%，使该方法成为一种可行的设计工具。对接触平面的圆柱体模拟微动磨损疤痕和深度，发现与实验结果和先前文献中的有限元建模结果一致。为了展示微动磨损模型的能力，模拟了三个实际应用：汽车座椅滑轨、工业应用钢丝绳和核电站蒸汽发生器管。
