摘要

基于首道失效和累积疲劳损伤规律，对飞机燃油管路系统在随机载荷作用下的动强度、可靠性和参数敏感性进行了研究。为了计算结构的动强度可靠度，提出了一种将随机振动谱分析、动强度可靠度理论和灵敏度分析方法相结合的方法。利用该方法对某型飞机燃油管路系统进行了动态强度可靠性和参数灵敏度分析。结果表明，该方法对工程结构的动强度可靠度评价方便、有效。

Dynamic strength reliability analysis of an aircraft fuel pipe system

Based on the first-passage failure and the accumulative fatigue damage rule, the dynamic strength reliability and parameter sensitivity of an aircraft fuel pipe system under a random load is discussed in this paper. To calculate the structural dynamic strength reliability, a method which combined the random vibration spectrum analysis, dynamic strength reliability theory and the sensitivity analysis method is proposed. Using the proposed method, the dynamic strength reliability and parameter sensitivity for an aircraft fuel pipe system is carried out. Results show that the proposed method is convenient and effective for the evaluation of the dynamic strength reliability of engineering structures.
