【摘要】 在讨论钢板弹簧疲劳寿命概率分布的基础上,研究了可靠度和置信度问题,给出了利用三参数Weibull分布计算疲劳寿命和可靠度的公式。计算实例表明,该法可方便地对所要求的任意可靠度和置信度进行寿命计算。更多还原

【Abstract】 In this paper reliability and confidence limit was studied on the basis of probability distribution discussion ofplate spring fatigue lifetime, and calculating formula of fatigue lifetime and reliability to make use of three-parameterWeibull distribution was given. This method in application to lifetime calculation of arbitrary reliability and confidence limithad been verified by example.更多还原
