| 摘 要： | 采用量纲理论对结构在冲击波载荷作用下的几何相似模型律进行分析,得到了结构满足几何相似模型律的条件. 应用LS-DYNA对一系列几何形状相似,尺寸不同的矩形板结构进行数值验证计算,证明了冲击波载荷作用下结构应力应变响应满足几何相似模型律的合理性和可靠性.

| Abstract: | With dimensional analysis on a structure subjected to a shock wave,key factors influencing on the structural size scaling model experiment determining.The conditions of the structure model law is made.A series of rectangular plates are analyzed with the finite element analysis software LS-DYNA.With these numerical results,the rationality and reliability is confirmed on the conclusions from dimensional analysis. |
