采用有限元方法对超薄金属内衬复合材料压力容器结构进行分析.在分析中,几何模型中的封头段考虑了复合材料铺放角度和厚度沿平行圆半径变化,材料模型中的复合材料层和内衬层分别选用复合材料层合板理论和弹塑性理论进行分析,二者之间的界面变形协调性及不可贯入性引入接触分析进行考虑.数值结果表明:在工作压力下,容器复合材料层纵向应变均为拉应变,环向存在部分压应变,内衬层发生塑性变形;卸载后,容器的复合材料层处在拉应力状态,内衬层处在压应力状态.在此基础上,利用容器的简化模型,根据内衬层最大变形点荷载-位移曲线实现了容器内衬层局部屈曲模拟.容器水压应变测试和内衬局部屈曲观测结果与数值模拟结果吻合较好,验证了本文中分析的可靠性.
