摘    要:利用ANSYS有限元法对铜/塑自润滑滑块进行了结构优化。 在正压力不变的条件下,对两种不同截面的滑块进行了承载力和摩擦对比实验。 结果表明: 圆柱截面滑块的极限承载力为82.1kN/cm, 而菱形截面滑块的极限承载力为65.9kN/cm, 两种不同截面自润滑滑块的干摩擦因数均小于0.1, 与有限元法的优化结果一致。

Abstract: The structure of brass-plastics self-lubricating composites was optimized with the ANSYS finite element method. When the normal pressure of slideway is unalterable, the load carrying capacity of the self-lubricating slideway for cylinder section is heavier than that of the lozenge section. The experiments of friction and load carrying capacity for the different section self-lubricating slideway were done. The results show that the limit load carrying capacity of cylinder section slideway is 82.1kN/cm, but the limit load carrying capacity of lozenge section slideway is 65.9kN/cm, the friction coefficients of two types of different section slideway are less than 0.1. The results of calculation and experiment are accordant.
