摘 要: 利用ANSYS有限元法對銅/塑自潤滑滑塊進行了結構優(yōu)化。 在正壓力不變的條件下，對兩種不同截面的滑塊進行了承載力和摩擦對比實驗。 結果表明： 圓柱截面滑塊的極限承載力為82.1kN/cm， 而菱形截面滑塊的極限承載力為65.9kN/cm， 兩種不同截面自潤滑滑塊的干摩擦因數(shù)均小于0.1， 與有限元法的優(yōu)化結果一致。

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.
