摘要
通过搭建试验测试平台,模拟高速破片对油箱的侵彻过程,对高速破片侵彻过程中破片入射速度,箱体内压力,破片在箱体内速度的衰减和箱体内气腔大小的数据进行测量,分析了水锤作用过程中这些参数之间的关系。结果表明:在水锤效应作用的过程中,第二阶段在箱体内产生的压力最大,破片的速度衰减和气腔的大小没有关系,但和箱体是否加盖有关,入射速度对压力大小影响较大;在容器加盖的前提下,增大破片动能对容器前面板的毁伤越严重。
By setting up the test platform,the penetration process of high speed fragments into the fuel tank,the incident velocity of the fragments during the penetration process,and the pressure inside the tank are simulated. The attenuation of fragment velocity in the box and the change data of the gas chamber in the chamber are measured and the relationship between these parameters during the action of the hydrodynamic ram is analyzed. The results show that the pressure produced in the second stage is the largest in the water hammer effect. The size of the gas chamber and the velocity of the fragment are not related to whether the box is capped or not,but the incident velocity has a great effect on the pressure. Under the condition of capping,the damage to the front panel of the vessel is more serious by increasing the kinetic energy of the fragment.
