摘　　要：为了更好地研究柴油机连杆小头衬套的摩擦性能,利用摆动摩擦磨损试验台开展典型工况下的正交试验,提出一种关于衬套摩擦性能因素的模糊综合评价方法,分析影响连杆小头衬套摩擦性能的单因素主效应、双因素交互效应,得到各因素对摩擦性能的影响。模糊综合分析结果表明:影响连杆小头衬套摩擦性能的单因素由大到小依次为施加载荷、摆动频率、加载方式,施加载荷与摆动频率的交互效应对摩擦性能的影响显著。In order to study the friction performance of the connecting rod bushing of diesel engine,the orthogonal test is carried out by using the swinging friction and wear test rig,and the test results under typical working conditions are obtained.A fuzzy comprehensive evaluation method for the friction performance of the bushing is put forward,and the single-factor main effect and double-factor interaction effect affecting the friction performance of the connecting rod bushing are comprehensively analyzed,and the influence degree of each factor on the friction performance is obtained.The results of fuzzy comprehensive analysis show that the influence of single factor on the friction performance of connecting rod bushing is in the following order:applied load,swinging frequency,loading mode,and the interaction between applied load and swinging frequency has significant influence on the friction performance.
