摘要
高压储氢技术是目前最接近产业化的丰载储氢技术，高压储氢容器是该技术的核心设备，对其进行力学分析对设计这类容器十分重要。提出了一种碳纤维缠绕铝合金内村高压储氢容器的力学分析方法。通过对碳纤维增强层进行模型简化，将复合材料容器的复合层简化为1个环向缠绕层和1个轴向缠绕层的2个子模型；通过对子模型进行弹性力学分析，推导出简体上纵向和环向缠绕相结合的纤维层的应力公式。由该计算公式得到的结果具有较好的正确性，其误差在6％以内，可以满足工程计算。
The technology of high-pressure hydrogen storage mostly approaches the industrialization among all hydrogen storage technologies. High-pressure hydrogen storage vessel is the key equipment of this technology, so it is important to analyze the mechanics of this type of vessel. This paper presents a mechanical analysis method of carbon fiber filament wound high-pressure hydrogen storage vessel with aluminum alloy liner. Based on simplifying the carbon fiber filament wound layer and inner cylinder, the wall of the composite material vessel are simplified into two sub-models, hoop winding layer and longitudinal winding layer. By analyzing elastic mechanics of two sub-models, the formulas on cylinder of carbon fiber filament wound layer can be deduced. The result calculated from this formula is close to the truth, and the errors are below 6 %. It can satisfy engineering computation.
