针对内爆炸毁伤压力载荷作用下金属叠层板的抗爆吸能特性问题，设计了内爆炸舱室试验模型，开展了舱室内爆炸作用下叠层板响应特性试验研究。利用试验验证的仿真模型，对相同质量的固支单层板和叠层板结构进行数值计算，对比分析了相同内爆载荷下2种靶板的塑性变形、应变分布以及抗爆性能的差异。在此基础上，进一步研究了叠层板的层数、单层厚度以及层间距离对其响应特性的影响规律，本文的研究结果可为多层防护舱壁的抗爆设计提供参考。
Aiming at the anti-knock energy absorption characteristics of metal laminates under internal explosion damage pressure load, an internal explosion chamber test model was designed and the response characteristics of metal laminates under internal explosion were investigated. By using the simulation model verified by experiments, the numerical calculation of the fixed single-layer plate and laminated plate structures with the same mass is carried out. The differences of plastic deformation, strain distribution and anti-detonation performance of the two types of target plates under the same implosion load are compared and analyzed. On this basis, the effects of the number of layers, the thickness of single layer and the distance between layers on the response characteristics of laminated panels are further studied. The research results of this paper can provide a reference for the anti-knock design of multi-layer protective bulkhead.
