摘　　要：针对装甲车辆在外场可靠性鉴定试验中考核严酷度一致性和试验结果可比性较差的问题,通过分析装甲车辆可靠性影响因素,构建可靠性试验严酷度评价指标体系。利用等效损伤原理,将可靠性加速试验理论应用于装甲车辆可靠性试验严酷度评价中,建立基于故障物理的单应力、多应力和单应力组合可靠性试验严酷度评价模型。通过某装备可靠性试验剖面应用实例,分析2个试验剖面下各应力因素可靠性试验相对严酷度,实现了装甲车辆可靠性试验严酷度定量评价。结果表明,该模型为可靠性鉴定试验剖面设计和试验结果评价提供依据。In view of the poor consistency of severity and poor comparability of test results in the reliability qualification test of armored vehicles in the field,the severity evaluation index system of reliability test is established by analyzing the influencing factors of armored vehicle reliability.Based on the equivalent damage principle,the reliability accelerated test theory is applied to the severity evaluation of armored vehicle reliability test,and the severity evaluation models of single stress,multi-stress and single stress combination reliability test based on failure physics are established.Through the application example of the reliability test profile of a certain equipment,the relative severity of the reliability test of each stress factor under two test profiles is analyzed,and the quantitative evaluation of the severity of the reliability test of armored vehicles is realized.The results show that the model provides a basis for the design of reliability qualification test profile and the evaluation of test results.
