HCSR 舱段模型中端部梁剖面属性对扭转变形的影响

摘要

针对HCSR强度计算中为合理考虑模型之外的构件对模型端面的弹性约束，须在三舱段模型两端施加端部约束梁的规定，分析端部约束梁对于三舱段模型的扭转变形的影响，采用数值试验的方法，进行了端部约束梁的剖面属性对于其扭转变形的敏感性分析。%The end constraint beams is a new method for the boundary of in direct strength analysis ( DSA) for cargo hold in HCSR , which can consider the flexible constraint of the rest structure of the cargo hold model to the end section .The effect of the end constraint beams upon the torsional deformation in DSA of the cargo hold model was studied by numerical experiments , and a sensitivity analysis was carried out .
