§5常用机械零件的可靠性设计前面我们曾经介绍了应用随机抽样法可近似求得产品的理论寿命分布,下面我们将进一步说明如何应用所学的基本的理论分布和有关的强度理论去解决机械零件的(强度)可靠性设计问题。一、机械零件的失效理论1.强度、负载和寿命之间的一般关系(1)强度一应力分布关系在可靠性技术中强度和负载*(如应力)的变化可用概率分布形式表示,这些
§5 commonly used mechanical parts of the reliability of the design We have previously introduced the use of random sampling method can be approximated to obtain the theoretical life of the product distribution, below we will further explain how to apply the basic theoretical distribution and the theory of strength to solve the mechanical Part (Strength) Reliability Design Issues. First, the failure theory of mechanical parts 1. The general relationship between strength, load and life (1) the relationship between strength and stress distribution in the reliability of the strength and load * (such as stress) can be expressed in terms of probability distribution, these
