摘要

对于平板在水下非接触爆炸下的结构响应问题,学界目前常采用仿真和试验手段开展研究。但目前的仿真手段主要采用ALE方法进行,计算效率低且在中远场计算中难以得到真实的结果,而试验手段成本较高。基于能流密度公式和TAYLOR平板理论对平板水下非接触爆炸冲击波载荷与速度场等效关系展开研究,提出了冲击波载荷和等效初速度场的等效换算方法,建立了平板初速度场与水下爆炸参数的等效关系并开展试验验证。结果表明,基于能流密度的冲击波等效初速度场具有更好的计算精度和效率,这一方法可作为研究平板或者简单板架在水下爆炸冲击波作用下结构响应的一个重要的等效计算方法。

Abstract

Simulation and test methods are often used to study the structural response of a flat plate under underwater non-contact explosion. At present, ALE method is mainly used for simulation, which has low computational efficiency and is difficult to get real results in middle and far field calculation, and the cost of test method is high. Based on the energy flow density formula and TAYLOR plate theory, the equivalent relationship between the shock wave load and velocity field of a non-contact underwater explosion on a flat plate was studied. An equivalent conversion method between the shock wave load and the equivalent initial velocity field was proposed, and the equivalent relationship between the initial velocity field of the flat plate and the parameters of the underwater explosion was established and verified through experiments. The results show that the equivalent initial velocity field of shock wave based on energy flux density has better calculation accuracy and efficiency, and this method can be used as an important method to study the structural response of plate or simple plate frame under underwater explosion shock wave.
