摘要: 针对钛合金内衬碳纤维缠绕压力气瓶水压试验后轴向缩短的现象,利用ANSYS有限元软件对其水压过程进行模拟计算,通过对气瓶筒身段及封头段各方向位移、应变计算结果的分析,明确了气瓶水压试验后轴向缩短是由封头处内衬外扩残余塑形变形引起的,利于此类气瓶结构设计的优化及尺寸稳定性的提高。

Abstract: Aiming at the axial shortening phenomenon of the carbon filament-wound pressure cylinder with titanium alloy liner after hydrostatic test, the finite element software ANSYS was used to carry out the simulation calculation. Through the analysis of the displacement and strain calculation results of the cylinder body and dome, it is clarified that the fundamental reason for the axial shortening of the cylinder after hydrostatic test is outwardly residual deformation of the dome, and it will be conducive for the cylinder to optimize structural design and improve dimensional stability.

Key words: composite cylinders, carbon fiber, titanium alloy, finite element
