摘　　要：疲劳强度在机械零件设计中的应用不同于静强度设计，由于设计时计入了应力集中、表面状态、尺寸及加载方式等影响因素，故更加符合动态实际情况．本文阐述了正确选择影响零件疲劳极限主要系数的途径，介绍了疲劳强度设计在机械零件中的几种计算方法及应用。The application of fatigue strength about machine parts design is different from that of static strength design.The fatigue strength design includs the affecting factors such as localired stress,surface state,dimensions,loding methods and sonn.So it fits the actual dynamic state.This paper descripts the method of selecting the main coefficients that affect the fatigue altimate strength of machine parts and introduces several calculating methods and applications of the fatigue strength design about machine parts.
