摘　　要：文摘应用解析计算的方法对铝内衬碳纤维全缠绕复合材料气瓶在内压情况下的弹塑性历程进行了分析,推导并得到了气瓶的自紧压力,通过水压应变测试及疲劳试验的方法进一步验证了计算结果的合理性。经对比分析,文中提到的计算方法可用于今后相似结构气瓶的自紧力计算。Calculation analytical method is applied to aluminium liner carbon fiber winding composite gas cylin- der during elastic-pLastic process under inner pressure, autofrettage pressure is obtained from inference. The rationali- ty of the calculated results is verified through hydrostatic strain test and fatigue test method. By comparative analysis , the calculation method can be applied to similar structure gas cylinder autofrettage pressure calculation in the future.
