摘　　要：以正交试验方法设计销盘摩擦副滑动摩擦磨损的试验方案,在MMW-1A多功能立式摩擦磨损试验机上研究载荷、速度、时间对摩擦因数的影响。通过极差分析和方差分析得到上述因素对摩擦因数影响的权重次序,结果表明载荷对摩擦因数具有最显著影响。建立销盘摩擦副的几何模型,运用有限元分析软件ANSYS仿真分析载荷变化对接触应力的影响,结果表明,接触界面的压力分布不均匀,呈现中间小、边缘大的态势;接触应力数值大小随载荷变化而改变,但应力分布形态不受其影响。The sliding friction and wear test scheme of pin disk friction pair was designed with the method of orthogonal experiment. The effect of load, speed, time on friction coefficient was researched on the MMW-1A muhifunction vertical friction and wear testing machine. Through the analysis of range and variance, the weight sequence of the above-mentioned factors on the friction coefficient was obtained. The test results show that the load has the most significant impact on the friction coefficient. The geometric model of pin disk friction pair was established, the effect of the load on the contact stress was analyzed by using the finite element analysis software ANSYS. The analysis results show that the pressure distribution on pin contact interface is not uniform, which is small in the middle and large in the margin ; With the change of the load, the value of contact stress may change, but not the stress distribution.
