摘　　要：用有限元软件ANSYS建立复合材料耐压壳体的有限元模型,建模中将纤维缠绕层作为层合板来处理。耐压壳体柱段采用螺旋方式缠绕,忽略封头处缠绕层厚度及缠绕角度不断变化。针对耐压壳体承受外压均布载荷的状况,分析其在该状况下的应力、模态等特性。Finite element model of composite overwrapped pressure vessels is established by ANSYS finite element program.In the modeling,filament winding layers are handled as composite laminate.Wound spiral pattern is used in the column of pressure vessel,without considering various thickness and wrap angle of every unidirectional layer of the domes.Using the model,static stress and mode analysis are simulated under external pressure.
