【摘要】 通过对汽车构件、总成或整车破坏的直接因素和间接因素的分析,提出了在满足强化试验基本假设条件情况下用于描述构件强化当量关系的三种估计法,即寿命统计估计法、载荷谱估计法和系统估计法,并利用描述汽车产品失效的浴盆曲线及可靠性增长模式,提出了总成或整车强化当量关系的估计方法。更多还原

【Abstract】 After studying the direct and indirect factors causing the failures of a motor vehicle or its parts and components, three estimation methods for expressing the intensifying equivalent relation of parts and components upon meeting the fundamental postulated conditions of intensified tests are proposed, i. e. endurance statistic estimation, loading spectrum estimation and systematic estimation. Meanwhile an estimation method for the intensifying equivalent relation of motor vehicle or its components are raised by the aid of the "bathtub" curves illustrating the motor vehicle failures and reliability growth mode.更多还原
