【Abstract】 In the paper,the abrasion fatigue experiment and in elastic contact condition the determination of abrasion fatigue parameters of material are designed.By use of the method proposed,the fatigue parameters of epoxy_rubber composite material are measured.The abrasion fatigue limit stress is about(3.0～5.0)MPa and it will decrease with the increase of material elastic modulus.更多还原
