摘　　要：利用ANSYS有限元软件对重载自润滑复合材料进行设计,通过摩擦磨损实验测定了其摩擦磨损曲线。结果表明这种自润滑复合材料的承载能力达到100MPa,摩擦因数小于0.14;在承载能力为80MPa、摆动频率为8次/min及摆角为±30°的条件下,这种自润滑复合材料的磨损率低,使用寿命长。可见这种新型复合材料适合于制造低速、重载与耐磨条件下的自润滑轴承。A new self-lubricating composite was designed by using the ANSYS finite element method at high loads. The tribological experiment of this composite was carried out on an oscillatory sliding tribometer. The experimental results show that this composite against a 45 plain carbon steel shaft exhibits heavy load-carrying capacity of 100 MPa, and the friction coefficient is less than 0.14. Under the conditions that load-carrying capacity is 80 MPa, oscillatory frequency is 8 cycles per minute and the oscillatory angle is ±30°, this composite against a 45 plain carbon steel shaft reveals very low wear rate and relatively long service life. This composite is suitable to be used for self-lubricating sliding bearings at low speeds and heavy loading conditions.
