| 摘 要： | 基于应力———强度干涉模型,研究了机械可靠性的灵敏度。通过对设计参数求偏导数的方法,得到可靠性的灵敏度计算公式。给出了多种失效模式可靠性的灵敏度计算方法。以轴为实例,计算了可靠性的灵敏度。机械可靠性设计应该进行灵敏度分析,灵敏度大小做为再设计时,修改设计参数的依据。不进行灵敏度分析的机械可靠性设计是盲目的。

| Abstract: | Based on stress-strength interference model sensitivity of mechanical reliability is studied. By partial differentiation with respect to design parameters, we can obtain calculating formula for sensitivity of reliability. Under several failure modes, method that calculates sensitivity of reliability is presented. To take axle for example calculates sensitivity of reliability. Mechanical reliability design that does not analyze sensitivity is unreasonable. |
