摘要: 为提高Ⅲ型储氢气瓶的承载能力和使用安全性,针对Ⅲ型储氢气瓶定角度缠绕导致的纤维堆积应力集中问题,基于扩孔缠绕的优化设计方法,对气瓶的缠绕层铺层方案进行了研究,并运用ABAQUS-WCM软件建立气瓶有限元模型,分析扩孔前后气瓶的应力分布规律及其对承载能力的影响。研究结果表明,通过改变气瓶纤维缠绕孔径,可降低环向缠绕层应力,提高螺旋缠绕层应力,改善气瓶的应力集中现象,使环向缠绕层与螺旋缠绕层应力分布更加均匀。根据最大应力失效准则进行失效分析,结果表明,气瓶扩孔后最小爆破压力从100.1 MPa提升至103.4 MPa,增加了3.3%,增强了纤维的承载能力。环向缠绕层和螺旋缠绕层在各方向应力分担中发挥了更大作用,从而提升了气瓶整体的结构强度和性能。

Abstract: To enhance the load-bearing capacity and operational safety of type Ⅲ hydrogen storage cylinders, this study focuses on addressing the stress concentration caused by fiber accumulation in fixed-angle winding. Utilizing an optimized design method of expanded-aperture winding, the layup scheme of the cylinder’s winding layers was investigated. Finite element models of the cylinder were developed using ABAQUS-WCM software to analyze stress distribution patterns and their effects on load-bearing performance before and after aperture expansion. The results demonstrate that adjusting the fiber winding aperture reduces stress in the hoop winding layers, increases stress in the helical layers, mitigates stress concentration, and achieves a more uniform stress distribution between the two types of layers. Failure analysis based on the maximum stress failure criterion revealed that the minimum burst pressure increased from 100.1 MPa to 103.4 MPa after aperture expansion, representing a 3.3% enhancement and improved fiber load-bearing capacity. Both hoop and helical winding layers play a more significant role in stress distribution across multiple directions, thereby enhancing the overall structural strength and performance of the cylinder.
