Optimization Method of Improved Equipment Reliability Analysis Test based on Importance Measure

在对重要度理论和装备可靠性鉴定试验方法研究的基础上,重点探讨了重要度计算方法对装备可靠性鉴定试验优化的作用机理,提出了一种基于重要度理论的改进型装备可靠性鉴定试验优化方法;结合坦克可靠性鉴定试验过程,给出了重要度理论在改进型装备被试品和参试品确定、试验应力选择中的具体应用方法,并通过对改进型装备可靠性鉴定试验优化效果分析,讨论了该方法的有效性和先进性。

The introduction of the full paper reviews a number of papers in the open literature and then proposes the representation method in the title, which is explained in sections 1 and 2. Section 1 briefs the system assumptions and the equation of reliability importance measure. The core of section 2 consists of： （1） we build the reliability model of the tank integrated system, which is given by Fig. 2;（2） we analyze the component reliability in the tank integrated system, give the computation of component importance, and discuss the order of different component im？portance as in Table 1; （3） we get the scheme of the reliability test by determining the test object based on the component importance. Section 3 presents the optimal scheme of the reliability test based on the stresses sensibility. Results comparisons, presented in Table 2, and its analysis verify that the importance measure can determine the test objects and stresses, so as to crop military and the test cost.
