采用可靠性摸底试验和可靠性增长试验相结合的方法,对机轮碳刹车系统这一复杂机电系统进行了可靠性试验。直接针对寿命周期内的薄弱环节制定可靠性摸底试验和可靠性增长试验;在不改变系统失效机理的前提下,尽量提高可靠性试验的频率,节约试验时间;选择容易引起薄弱环节损伤的环境应力和工作应力以加速方式进行可靠性试验;将可靠性试验与系统中部件的寿命试验相结合。该方法特别适用于复杂系统的可靠性试验。
The reliability test was carried out on the complex electromechanical system of the carbon brake system of the wheel with a combination of reliability test and reliability growth test. Directly to the weak links in the life cycle to develop reliability test and reliability growth test; without changing the system failure mechanism under the premise of as much as possible to improve the reliability of the test frequency, saving test time; choose vulnerable to damage caused by weak environmental stress And work stress in order to speed up the reliability of the test; the reliability test and system components life test combined. This method is especially suitable for the reliability testing of complex systems.
