Multi-objective Optimization Using Grey Relational Analysis for Tribological Properties of Friction Pairswith Round Pit Surface Textures

为综合考虑微织构摩擦副的磨损与摩擦系数的优化,提出了基于灰色关联度分析法的Taguchi方法研究了圆坑型微织构摩擦副的磨损和摩擦系数的多目标优化。主要考虑全圆坑型微织构的直径、间距和深度对销、盘的磨损和摩擦系数的影响。然后运用Taguchi方法的信噪比进行单目标优化,采用方差分析检验控制变量影响的显著性。最后,采用灰色关联度开展多目标优化。得出圆坑直径是影响销、盘的磨损和摩擦系数多目标优化的主导因素,贡献率高达89.58%。

In order to comprehensively considering the wear and friction coefficient of friction pairs with round pit surface textures optimization,carrying out to understand tribological properties of friction pairs with round pit surface textures.The effects of diameter,distance and depth of micro-texture to pin and disc wear and friction coefficient were investigated.Then,responses were used alone in optimization study as an objective function.Taguchi’s signal to noise ratio was used.The effect of control factors on responses was determined by analysis of variance.Finally,responses were optimized simultaneously using grey relational analysis,it could be concluded that diameter was dominant parameter that affect multi-objective optimization of pin and disc wear and friction coefficient by 89.58%.
