| 摘 要： | 机械零部件可能发生多种失效模式,而且各个失效模式往往不是相互独立的.用理论方法计算相关失效模式下的可靠度需要做出一些假设或简化,可能带来较大的误差,失效模式的相关性使可靠性灵敏度的计算更加困难.根据灵敏度和偏导数的定义,提出了多种失效模式下可靠性灵敏度的数学模型,并用Monte Carb方法实现求解,探讨了如何获取合理...

| Abstract: | A mechanical component may fail in many modes that are usually not independent.Based on some hypotheses and simplified models,the reliability and sensitivity in correlated failure modes can be obtained by theoretical approaches which,however,bring large errors.According to the definitions of the sensitivity and partial derivative,the mathematical models about the reliability and sensitivity are put forward and solved by Monte Carlo method.How to obtain an appropriate sampling size and increment of the rando... |
