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.
