摘要：基于Archard磨损数学模型建立了锁圈与钢圈锁紧面的微动磨损模型，分析了在无喷丸应力状态下磨损

深度随循环周次的变化。通过ABAQUSSIGINI子程序施加初始喷丸残余应力，分析了不同喷丸应力对钢圈锁紧面

的接触压应力、滑移幅值、摩擦切应力等微动参量的影响。结果表明：在无喷丸应力时，磨损深度随循环次数的增加

而增大，最大磨损深度出现在钢圈锁紧面侧面接触边缘处。在循环周次150000周次下，随着喷丸应力的增加，钢圈锁

紧面侧面接触边缘的接触压应力、滑移幅值、摩擦切应力、磨损深度逐渐降低，同时微动参量向过渡圆角处转移。喷

丸应力在-100、-200MPa时对钢圈锁紧面起到较好的抗微动磨损效果。
