微动工况下柱面不同因素对平面磨损显著性的分析
|
摘要
为了研究二维柱面不同参数对平面磨损形貌的影响,基于改进的Archard磨损方程,建立二维柱面—平面微动磨损模型,并通过对比Hertz接触理论,验证了有限元模型的正确性。运用正交试验技术设计试验方案,对在不同因素下平面的磨损轮廓进行了数值模拟,并分别从平面的磨损宽度和磨损深度分析了柱面半径、柱面材料弹性模量、泊松比三个参数对平面磨损轮廓的影响。对平面磨损轮廓的影响因素显著性分析表明:柱面材料的弹性模量最大,柱面半径次之,柱面材料的泊松比最小。
Based on the improved Archard equation of wear,two-dimensional rigid cylindrical and in-plane fretting wear models are established. The plane wear profile is numerically simulated by the rigid-plastic finite element method. The effects of rigid cylindrical radius,cylindrical elastic modulus and poisson's ratio on the plane wear profile are analyzed,taking the wear width and wear depth of the plane as the optimization index. By the use of integrated balance method,the best rigid cylindrical structure and material parameters are obtained and validated. The results of the study on the effect of plane wear profile show that the elastic modulus of the cylindrical material is most significant. Followed by the cylinder radius,and the poisson's ratio of the cylinder material is least significant.
