在本文中，入射波的透射部分被认为是修改泰勒的解决方案，这是用来扩展其应用程序的分析模型，以预测响应的板与不同的材料性能。系统地研究了板的材料特性和边界条件对流体和结构动力学的影响。分析结果与详细的动态有限元模拟结果进行了比较，两者吻合良好。结果表明，该分析方法是有效的，适用于不同材料性能的板在水下爆炸载荷作用下的变形。结果表明，泰勒的小阻抗板的结果是无效的，这表明了一个潜在的应用领域的解析方法。
In this paper, the transmitted part of the incident wave is considered to revise Taylor’s solution, which is used to extend its application for analytical models to predict the response of the plate with different material properties. The influence of the material properties and the boundary condition of the plate on fluid and structural dynamics is systematically investigated. The analytical results are compared with those of detailed dynamic FE simulations and the two are in good agreement. The results indicate that the analytical method is valid and suitable for the plates with different material properties subjected to underwater explosion. It is found that Taylor’s results of the plate with small impedance are invalid, which indicates a potential application field for the analytical method.
