随着国防装备的快速发展,对型号的可靠性和寿命提出了更高的要求。为满足型号的高可靠、长寿命要求,可靠性试验成为目前研究的重点。以火箭发射平台所用的液体摆水平传感器为研究对象,分析液体摆在环境温度应力作用下的失效原因;选择适用的加速退化模型,建立一种基于加速性能退化的可靠性模型,并通过试验评估进行论证。 With the rapid development of national defense equipment, higher requirements are put forward on the reliability and life expectancy of models. To meet the type of high reliability, long life requirements, reliability testing become the focus of the current study. The liquid level sensor used in the rocket launching platform is taken as the research object to analyze the failure reason of the liquid under the ambient temperature stress. The suitable accelerated degradation model is selected to establish a reliability model based on the degradation of acceleration performance. To demonstrate.
