实验采用 4种不同厚度底板的圆筒模型。以不同下落高度撞水 ,测量底板径向压力分布和应变响应。数值计算中联立求解底板弹性动力响应方程和流场方程。实验和数值分析表明底板的初始几何缺陷和弹性变形对冲击压力具有较大影响
Experiments using four different thickness of the floor of the cylinder model. Blow at different heights to measure the radial pressure distribution and strain response of the floor. Solving Elastic Dynamic Response and Flow Field Equation of Slab in Numerical Calculation. Experiments and numerical analysis show that the initial geometric defects and elastic deformation of the bottom plate have a greater impact on the impact pressure
