摘　　要：为了在较短时间内有效地提高并考核机载武器可靠性水平,研究了机载武器的特点,将加速试验方法和可靠性增长试验方法相结合,提出了一种面向实战条件的机载武器加速可靠性增长试验方法。在机载武器面向实战任务剖面分析的基础上,根据疲劳损伤累积原则和振动环境下疲劳等价关系,给出了关于振动应力的加速可靠性增长试验方法。同时针对机载武器多可靠性指标需求,给出了多指标可靠性综合试验方案,并制定了面向实战条件的加速可靠性增长试验剖面,实现对机载武器多可靠性指标同时增长与考核,有效缩短了试验时间。通过实例应用表明,该方法考虑了机载武器实战环境条件对可靠性的影响,显著提高了机载武器可靠性增长试验效率。Reliability is one of the most important indexes of airborne weapon. To improve and assess the reliability of airborne weapon effectively in a limiting time, the character of the airborne is studied, and an accelerated reliability growth test method of airborne weapon was proposed based on the theory of accelerated test and reliability growth test. The actual battle mission profile of airborne weapon was analyzed, and the accelerated reliability growth model was put forward according to the Miner rule. The model was used to curtail the reliability growth time. Then, to satisfy the requirement of reliability on airborne weapon, the synthetic reliability test scheme and test profile for mulfmomial reliability indexes were established. With the method, the Embarkation Flight reliability and flying reliability of airborne weapon were grown and assessed simultaneity. The instance analysis shows that the method is reasonable and straightforward for engineering application, and makes the reliability growth test effective to improve the reliability level.
