基于二维柱面-平面模型的有限元接触分析,发现接触状态由部分滑移转变为整体滑移的临界应变载荷幅值与法向力近似成正比。采用Archard模型以及多层节点更新方法,利用有限元二次开发数值模拟锆合金的微动磨损。发现锆合金的磨损速率随应变载荷幅值增加而增加,在部分滑移状态下增长缓慢,在整体滑移状态下快速增长。在整体滑移状态下,磨损速率随法向力增加先增加后减小;在部分滑移状态下,磨损速率随法向力增加缓慢减小。 Based on the finite element contact analysis of two-dimensional cylinder-plane model, it is found that the magnitude of the critical strain load changing from partial slip to global slip is approximately proportional to the normal force. Using Archard model and multi-layer node updating method, the fretting wear of zirconium alloy is numerically simulated by finite element method. It is found that the wear rate of zirconium alloy increases with the increase of the strain load amplitude, slowly increases in the partial slip state and rapidly increases in the overall slip state. The wear rate increases first and then decreases with the increase of normal force under the condition of overall slippage. In partial slippage, the wear rate decreases slowly with the increase of normal force.
