利用能量守恒和动量定理，通过计算靶板塑性变形挠度，以极限塑性应变为准则，建立了爆炸冲击波载荷作用下舱壁结构中心区域破口尺寸的计算方法，并开展了近距离空爆模型试验。试验结果表明，本文建立的计算方法具有一定准确性，理论计算结果与本文试验结果相对误差为14.2%，与参考文献试验结果对比误差为10.9%，可对舱壁结构在爆炸冲击波作用下产生的破口尺寸进行快速估算。
Based on the energy conservation and momentum theorem, the plastic deformation deflection of the target plate is calculated, and the limit plastic strain is taken as the criterion, the calculation method of the fracture size in the central area of bulkhead structure under the blast wave load is established, and the short range air explosion model test is carried out. The experimental results show that the calculation method established in this paper has a certain accuracy. The relative error between the theoretical calculation results and the experimental results in this paper is 14.2%, and the error between the theoretical calculation results and the experimental results in references is 10.9%. It can be used to quickly estimate the fracture size of bulkhead structure under the action of explosion shock wave.
