关于工程设计中可靠性指标之界限的确定

The Determination of the Bounds of the Reliability Index In the Engineering Design

本文利用Ｃｈｅｂｙｓｈｅｖ不等式和较优且较敏感的指数函数求得工程设计中可靠度Ｒ的最大下界，再利用Ｔａｙｌｏｒ公式求得失效概率ｐｉ的最小上界及可靠性安全系数ｎＲ的界限。

The Chebyshev's inequality and the more excellent sharp exponential form is used to obtain the greatest lower bound of R in the design of engineering. Then the least upper bound of Pj and the bound of the safety coefficient of reliability nR are obtained by using Taylor formula.
