摘要
阐述了板结构在爆炸冲击作用下的破坏情况及其材料破坏的断裂准则,介绍了利用AN-SYS软件对薄板结构在冲击载荷下有限元计算的方法,并对某开关柜板的四周薄板结构在15KA故障电流下发生爆炸时的引起的冲击载荷作用下进行了瞬间动态应力分析,并利用其程序设计语言APDL确定出该板可承受的最大冲击载荷的峰值。
The finite element method for calcuating the maximal impact loacl of the sheet metal is introduced by the destroy of sheet metal and its rupture roles under the exploded impact load. The instant dynamic analysis of a certain switch tank＇ s plate when its 15kA fault current occur is presented and the maximal impact load under which the plate could be endured are calculated by using the software ANSYS and its developing language of APDL.
