基于扩孔缠绕的Ⅲ型储氢气瓶铺层优化及应力分析
Layer design and stress analysis of type Ⅲ hydrogen storage cylinders based on hole-expansion winding
摘要
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.Utili-zing 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 re-sults 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 pres-sure increased from 100.1 MPa to 103.4 MPa after aperture expansion,representing a 3.3%enhancement and im-proved fiber load-bearing capacity.Both hoop and helical winding layers play a more significant role in stress distri-bution across multiple directions,thereby enhancing the overall structural strength and performance of the cylinder.关键词
