环向纤维增强钢压力容器设计分析

Design analysis of the hoop fiber-reinforced steel pressure vessels

用弹性理论分析方法 ,得到了环向纤维增强钢压力容器(压缩天然气气瓶 )在内压作用下的应力。给出了气瓶爆破压强以及钢筒和纤筒壁厚的计算方法。讨论了提高气瓶疲劳强度的技术途径。算例表明 ,计算值与实验结果符合良好。

Based on the elastic stress analysis, the stresses of the hoop fiber reinforced steel pressure vessels (compressed natural gas bottle) under internal pressure are obtained. The calculation methods for the burst pressure of gas bottle, thicknesses of the steel cylinder and the fiber reinforced composite cylinder are given. The technical approach improving the fatigue strength of the gas bottle is discussed. The calculated results are in agreement with those obtained from the test.
