球形破片杀伤元对车辆油箱毁伤效应研究

Research on the Damage Effect of Spherical Fragment Killing Element on Vehicle Fuel Tank

应用流固耦合有限元仿真技术研究了球形破片和冲击波对卡车油箱的侵彻效应,获取了油箱在球形破片侵彻下的动态压力规律,揭示了侵彻过程中的“水”锤效应,分析了不同油液体积下的油箱侵彻效应,并对冲击波叠加效应下油箱毁伤情况进行分析。在毁伤分析基础上对增加陶瓷装甲防护后的油箱抗侵彻能力进行了仿真研究,结果表明陶瓷防护有效,在工程上有一定的实用价值。研究成果为特种车辆油箱的抗侵彻能力评估和防护方案的设计提供了重要的参考。

The penetration effect of military vehicle tank under the spherical fragment killing element is researched with fluidstructure interaction.The dynamic pressure rule and the"water"hammer during penetration are revealed,and moreover,the penetration effect with different oil volume is analyzed.The penetration-resistance ability of tank with ceramic armor is simulated,and the results show that the ceramic protection of tank is effective and valuable in engineering.The result can provide important reference for the evaluation of the penetration-resistance ability and the design of defense project on fuel tank of military special vehicle.
