【摘要】 在机械装备中经常使用过盈配合,过盈配合拆解的难度大,再制造拆解时常常会造成配合界面损伤而导致零件无法再制造。文章针对过盈配合拆解的界面损伤,设计了过盈配合拆解的模拟试验,阐述了试验原理和过程;根据试验结果,分析界面损伤的形式和产生损伤的机理,确定了界面损伤定量表征参数为拆解界面损伤深度;研究了过盈量、材料类型与界面损伤的关系;对Archard模型进行修正,结合试验数据,建立了界面损伤预测模型。更多还原

【Abstract】 In machinery equipment,interference fit is widely used.It is difficult for interference fit dismantling.Remanufacturing dismantling often damages the interface which means that parts can not be remanufactured.To research the interface damage of interference fit dismantling,the simulation test of interference fit dismantling is designed,and its principle and process are introduced.Based on the test results,the form and the mechanism of interface damage are analyzed,and the quantitative parameter for the characterization of interface damage is confirmed as dismantling interface damage depth.The relation among the magnitude of interference,the type of material and interface damage is explored.With Archard model corrected and combining with experimental data,the prediction model of interface damage is established.更多还原
