摘要
研究冲击载荷作用下加筋板架的动态响应对于深入理解相关摇摆台的耐撞性设计具有重要的指导意义。应用数值仿真的方法对4种典型加筋板架进行分析计算,得到不同加筋情形下板架的动态响应特征,并从变形趋势、应力、应变三个方面进行对比分析,进而选择出了较好的方案。
It is significant to study the dynamic response of stiffened panels under impact loading for luther investigation of structural crashworhiness designing about a swaying platform.4 typieal models of tile stiffened panels are analyzed by numerical simulation and the dynamic response characteristics are obtained with the tour kinds of stiffened panels. At the same time,the simulated results are compared with the experimental data from three aspects of deformation trendiness ,strain and displacement to show a better program.
