用概率设计方程解决可靠性设计问题的探讨

Method of Settling Dependability Design Problem with Probability Design Equation

从推导与分布类型无关的可靠度下限引出概率设计方程 ,通过概率设计方程可实现用传统设计方法解决可靠性设计问题。为建立概率设计方程绘制了可靠度下限和安全系数间的关系曲线Rmin -n 。

The probability design equation is drawn out by deducing the dependability lowe limit which is irrespective with distributing types.Through the probability design equation,the dependability design problem can be solved with the traditional design method.The curve R min -n of the relation between the dependagbility lower limit and the safe factors is given in order to establish the probability design equation.It′s also illustrated by an example that the dependability design problem can be solved by probability design equation.
