摘要: 本文以固定在支架上的复合材料缠绕气瓶为研究对象,研究其在使用过程中的随机振动下的应力,结合三区间法和Miner 准则进行疲劳寿命评估。在此基础上,以最长寿命内衬为目标,对气瓶的固定件-绑带进行优化分析,并给出了快速确定绑带间距的方法。

关键词: 气瓶, 复合材料, 随机振动, 疲劳寿命, 优化

Abstract: The stress of a composite overwrapped pressure vessel (COPV) fixed on supports was investigated under a random vibration environment. The fatigue life of the COPV was evaluated by combining the Three Interval Method and Miner criterion. Based on the object of the longest fatigue life of liner,the belt spacing of the COPV is optimized,and a solution for quickly determining the belt spacing is proposed.

Key words: cylinder, composite material, random vibration, fatigue life, optimization
