摘　　要：运用ANSYS/LS-DYNA数值软件模拟液化石油气爆炸产生的破片撞击临近的LPG储罐的破坏过程。考虑入射角、接触面积、破片质量等因素,应用LS-PREPOST后处理软件对破片的侵彻过程、速度变化和影响破片撞击效果的破片特性做了相应分析,得出的结论对LPG储罐的布局及安全管理具有指导意义。The failure process of the fragment caused by liquefied petroleum gas explosion against the near LG storage tank has simulated using ANSYS/LS-DYNA numerical simulation software.A corresponding analysis has made about the penetration process,velocity change and the characteristics of fragments affecting the impact effect,considering the incident angle,the contact area,fragmentation quality and other factors.The conclusion has the guiding significance to the layout and safety management of LPG storage tank.
