摘要
通过动力学有限元工具构建经验公式对水锤效应进行撞击穿透数值模拟分析研究,得到比较有效的水锤效应模拟分析方法;对比研究文献资料的分析方法,得到合理有效的建模方法,通过分析摸清水锤效应的原理及其破坏机理。利用二级气炮发射子弹撞击充液的箱体进行试验,根据试验结果进一步验证水锤效应的原理;在此过程中,研究了试验控制方法,得到了该试验方法的控制流程;通过对速度、应变及压力的动态测试方法研究,得到了试验测试方法,最终建立油箱水锤效应试验方法。
The numerical simulation analysis of the impact of hydrodynamic ram phenomenon was carried out by constructing the empirical formula of dynamic finite element software to obtain the more effective numerical analysis method. By comparing the methods of literature analysis, a reasonable and effective modeling method was obtained.The principle of hydrodynamic ram phenomenon and its failure mechanism ware analyzed through simulation. Then,the experiment was carried out by using the two-stage air gun system. And the principle of the hydrodynamic ram phenomenon was further verified according to the experimental results. In this process, the experimental control method was studied and the control flow of the experimental method was obtained. In addition, by means of dynamic testing method of velocity, strain and pressure, the test method was obtained. Finally, the experimental method of hydrodynamic ram phenomenon of fuel tank was established.
