摘要
为确定船舶进气装置承受冲击波的能力,建立二维有限元模型。通过采用AUTODYN程序对进气装置在冲击波载荷作用下的受力情况进行理论分析,得到爆炸冲击波对进气装置的冲击作用力,表明船舷侧的百叶窗式格栅对冲击波有明显的衰减作用。
In order to evaluate the air inlet device＇s ability to withstand shockwave,two-dimensional finite element model is established. By using AUTODYN,the force acting upon the air inlet device under shock wave loading is analyzed. The results show that the ship side blinds can lowered the shock wave significantly.
