摘要
采用大型通用有限元软件MSC/DYTRAN,对歧口QK18-2海洋平台舱室结构内部密闭空间内爆炸载荷作用下变形和破坏的情况进行数值模拟研究,从结构的变形失效和构件能量吸收等方面对海洋平台的典型舱室结构在不同加强方式下的动态响应进行数值仿真计算,并依据TNT当量法对该海洋平台某舱室进行了油气爆炸后的风险计算。
The explosion pressure of flammable gas and the cabin structure dynami cal responding problem of QK18-2 offshore platform under inner- blast is simulated based on MSC/DYTRAN. The dynamical response characteristics of cabin structure is caculated through the structure damage deformation and energy absorption. In this paper, the risk analysis of the cabin of QK18-2 offshore platform under oil gas explosion is studied by the TNT way.
