Abstract
Based on a simplified implosion load model, the effective acting time of implosion load in confined space and impulse saturation phenomenon were studied. The dynamic response of ideal rigid-plastic explosion suppression structure under internal explosion load was analyzed, and the theoretical formula was deduced and summarized, which is compared with the numerical simulation results. The results show that there is an effective acting time for the explosion load when an explosion occurs in the cabin. The total impulse of the explosion load in the cabin reaches saturation at the effective acting time, and the subsequent explosion load will not continue to deform the bulkhead structure. The effective action time is related to the action time of shock wave, peak value of shock wave and quasi-static pressure and the size of cabin.
