爆炸实验水池防护性能及动力学响应分析
Protective performance and dynamic response analysis of explosion testing pool
摘要
Abstract
In this work,in view of the design issues concerning the strength of the explosion testing pool,we simulated numerically the shock wave propagation in water and structural dynamic responses of the testing pool subjected to a 10 kg TNT explosion impact loading using the nonlinear dynamics program LS-DYNA.We also quantitatively calculated the capability of the air tank and the bubble curtain to weaken the shock wave in water.The results show that the weakening effect of the air tank on the shock wave peak pressure and the specific impulse is close to 50％ and 16.2％,that of the bubble curtain on the shock wave reflection and the specific impulse is as high as 86.2％ and 75.6％.Based on this,we further analyzed the mechanism of the impact loading and the structural response and carried out a preliminary investigation of the distribution and transmission of the explosion energy between each substance.Our work can be used as reference for the engineering design of similar explosion testing pools.关键词
