Experimental and numerical studies have been performed to investigate the blast responses of a stiffened panel under plane shock waves from air blast loading. The experiments were conducted in a novel explosion-proof tank testing system. Two trial tests were first conducted to validate the accuracy of the pressure sensors. After validation, a real blast test was performed to investigate the dynamic response of the stiffened panel under plane shock waves. The deformation and failure mode of the panel plating were obtained from the test. Numerical simulations were carried out with the mathematical method and good agreement is obtained between the numerical and the experimental results. The results show the antiknock performance of the structure is different in different directions under the action of the stiffener. In addition, the effect of peak pressure magnitude and shock wave type on the response of the stiffened panel is also discussed.

已经进行了实验和数值研究，以研究加筋板在空气冲击载荷的平面冲击波下的冲击波响应。实验是在一种新型防爆罐测试系统中进行的。首先进行了两次试验测试以验证压力传感器的准确性。验证后，进行了真实的爆炸试验，以研究加筋板在平面冲击波下的动态响应。从试验中得到面板镀层的变形和失效模式。用数学方法进行了数值模拟，数值与实验结果吻合良好。结果表明，在加强筋的作用下，结构的抗爆性能在不同方向上是不同的。此外，
