| 摘 要： | 基于强度-应力干涉理论设计的零件,通常由于没有考虑服役时间导致零件疲劳失效.这种静可靠度设计不能正确反应零件在服役过程中可靠度的变化,印使设计一定的安全裕度也往往在服役过程中由于可靠性不满足要求而导致零件失效.充分考虑服役年龄对机械零件强度分布的影响,建立零件强度-应力可靠度动态模型,探讨疲劳失效对零件可靠度的变化;通...

| Abstract: | The part designed based on the strength-stress interference model,for without considering fatigue failure and ignoring service time,is easy to fail.This static part reliability can not reflect part reliability variation in the service course and parts fail because of unreliability in the working course,even though a definite safety margin is designed to keep parts regularly working.In this paper,service time and fatigue failure was considered to have influence on the strength distribution of mechanical part... |
