| 摘 要： | 以ANSYS通用有限元为手段,使用非线性分析方法,对纤维缠绕复合材料压力容器进行有限元分析,在此模型基础上进一步研究了压力容器的渐进损伤,以失效因子为参数,讨论了失效单元逐层失效的过程。结果表明,复合材料压力容器在2.0MPa时树脂完全开裂,最初纤维断裂出现在应力为8.1MPa的桶身与封头连接处,而后经向纤维逐渐断裂,此位置最终在8.9MPa下纤维全部断裂。

| Abstract: | Filament-wound composite pressure vessel was studied using non-linearity method with ANSYS finite element software in this paper. On the basis of this model, progressive damage of the pressure vessel was ana- lyzed according to Hashin failure criterion and maximum stress criterion. The results show that the resin will split completely under a given stress of 2.0MPa, and the original fracture of carbon arises at the connection area between the ladle body and the end plate under a stress of 8.1MPa, and then the carbon will break down gradually till the entirely failure under the stress of 8.9MPa. |
