摘要
采用大型有限元软件MSC.DYTRAN,对泄漏气体爆炸载荷进行数值计算,并对辽河作业一号海洋平台某舱室结构在爆炸载荷作用下的动态响应进行了数值模拟研究。分别从结构的变形失效形式和构件能量吸收等方面研究了海洋平台舱室结构在可燃气体爆炸载荷作用下的破坏机理和响应特征。
The numerical calculations of blast wave from gas explosion are carried out with the code MSC. DYTRAN. The dynamical responding of a cabin structure of LH-1 offshore platform under inner-blast loads is simulated. The dynamical response characteristics of the cabin structure is studied through the structure damage deformation and energy absorption by components of the cabin structure.
