摘要
利用ANSYS建立某型舰载机前机身模型,通过对导弹爆炸冲击作用的分析,并利用LS-DY-NA对舰载机前机身模型进行加载,得出爆炸作用对舰载机前机身的毁伤效果。仿真表明:在爆炸冲击波作用下,形变最大位置在驾驶员舱和机身连接处,压强最大位置在雷达罩侧面中心处。仿真结论有助于从结构和材料方面指导舰载机机身防护。
The airplane forepart model was made by ANSYS. By analyzing the explosion shock effect of missiles, and loading the shock wave to the forepart by LS-DYNA, the explosive damage effect of the forebody could be concluded. Simulated results showed that the max deformation was located on the joint of fuselage and pilot cabin, the max pressure located on the side center of radome. The conclusion can help to direct the defense of fuselage from structure and material.
