摘要
介绍了一种基于有限元数值模拟的复合气瓶优化设计方法,利用ANSYS的APDL语言建立了与全缠绕复合气瓶力学特性尽可能一致的有限元模型,实现了气瓶封头段螺旋缠绕层的变厚和变角度,并按照美国DOT-CFFC设计要求对复合气瓶进行了优化设计,提高了气瓶的容重比和可靠性。
The composite vessel is widely used to replace the steel cylinder for its excellent performances such as high specific strength,designable,good corrosion resistance.An optimization design method was presented based on FEM.The finite element model was established with APDL language,which has maximum consistency with the mechanical characteristic of full-wrapped composite vessel,The optimization design was made according to the design criteria of DOT-CFFC.It improves the rate of volume and mass and the reliability of the vessel.
