摘要： 针对在铝内胆复合材料储氢瓶（又称为“III型储氢瓶”）设计阶段难以根据设计的气瓶爆破压力和疲劳寿命确定内胆厚度和纤维应力比的问题，研究了III型储氢瓶爆破压力与疲劳寿命的关系。首先，构建了III型储氢瓶的有限元计算模型，提出了基于有限元的气瓶爆破压力和疲劳寿命的预测方法，分析了在内胆厚度和纤维应力比两个因素影响下III型储氢瓶的应力分布状态。其次，研究了内胆厚度和纤维应力比对III型储氢瓶爆破压力和疲劳寿命的影响规律，结果表明：在一定的内胆厚度和纤维应力比范围内，增大内胆厚度，气瓶爆破压力提升较小；增大纤维应力比，则气瓶爆破压力提升较大；III型储氢瓶对数疲劳寿命与内胆厚度和纤维应力比均基本呈线性关系。最后，基于纤维缠绕压力容器爆破压力计算公式和III型储氢瓶对数疲劳寿命拟合关系式，得到了不同条件下III型储氢瓶爆破压力与疲劳寿命的关系式。研究结果可为III型储氢瓶结构的优化设计提供参考。
Abstract: Aiming at the problem that it is difficult to determine the liner thickness and fiber stress ratio according to the designed cylinder burst pressure and fatigue life in the design stage of composite hydrogen storage tank with aluminum liner (also known as ‘type III hydrogen storage tank’), the relationship between burst pressure and fatigue life of type III hydrogen storage tank was studied. Firstly, the finite element calculation model of type III hydrogen storage tank was constructed, the prediction method of cylinder burst pressure and fatigue life based on finite element was proposed, and the stress distribution of type III hydrogen storage tank under the influence of liner thickness and fiber stress ratio was analyzed. Secondly, the effect rule of liner thickness and fiber stress ratio on burst pressure and fatigue life of type III hydrogen storage tank was studied. The results showed that: in a certain range of liner thickness and fiber stress ratio, when the liner thickness increased, the increment of cylinder burst pressure increased lesser; when the fiber stress ratio increased, the cylinder burst pressure increased greatly; the logarithmic fatigue life of type III hydrogen storage tank was basically linear with liner thickness and fiber stress ratio. Finally, based on the burst pressure calculation formula of filament-wound pressure vessel and the logarithmic fatigue life fitting relationship formula of type III hydrogen storage tank, the relationship between burst pressure and fatigue life of type III hydrogen storage tank under different conditions was obtained. The research results can provide reference for the optimal design of type III hydrogen storage tank structure.
