摘要:
为提高微动磨损预测的准确性，考虑实际工况中温升的影响，通过引入随温度变化的磨损系数来修正能量耗散磨损模型并编写UMESHMOTION子程序，基于柱面/平面微动试验建立微动磨损的温度-位移耦合有限元模型。模型考虑了温度、应力和磨损之间的相互作用以及温度对摩擦因数的影响，通过与Archard模型进行对比来验证模型的正确性，探究材料塑性、温度和微动循环次数对接触表面磨损和温升的影响。仿真试验表明：修正的能量耗散磨损模型的磨损深度略小于Archard模型的磨损深度，且随着温度的升高两种模型之间的差距增大；不考虑材料塑性和温度的磨损深度偏小，考虑材料塑性的磨损轮廓不再是光滑的赫兹形状；随着循环次数的增加，接触表面的温度升高，温升峰值水平位置随着圆柱试件移动，磨损深度的增长速率由于温度的升高而变小，磨损轮廓突变点与磨损中心的深度差越来越小。
Abstract:In order to consider the effect of temperature rise on the accuracy of fretting wear prediction in actual working conditions, the energy dissipation wear model was modified by introducing a temperature-dependent wear coefficient. And the UMESHMOTION subroutine was compiled, while the temperature-displacement coupled finite element model of fretting wear was established based on the cylinder/plane fretting test. The model considered the interaction between temperature, stress and wear, as well as the effect of temperature on the coefficient of friction. The plausibility of the model was verified by comparison with the Archard model. The effects of material plasticity, temperature and number of fretting cycles on the wear and temperature rise of the contact surface were explored. Simulation experiments showed that the wear depth of the modified energy model was slightly smaller than that of the Archard model, and the gap between the two models increased with the temperature rise. The wear depth without considering plasticity and temperature was relatively small. The wear profile taking into account the plasticity of the material was no longer of a smooth Hertz shape. As the number of cycles increased, the temperature of the contact surface increased and the horizontal position of the temperature rise peak moved with the cylindrical specimen. Meanwhile, the growth rate of the wear depth decreased due to the increase in temperature. The depth difference between the abrupt change point of the wear profile and the wear center was getting smaller and smaller.
