新型乳化炸药动压减敏装置的数值模拟研究
Numerical Simulation on a Novel Dynamic Pressure Desensitization Device for Emulsion Explosives
摘要
Abstract
By using the dynamic finite element software LS-DYNA,we simulated the working process of a novel emulsion explosive pressure desensitization device,and investigated the characteristics of its flow field distribution and the influence of its structural design on the experimental results.The comparison of simula-tion and experiment results shows that the row spacing is the critical factor that determines the degree of accu-racy in experiment.For the novel dynamic pressure desensitization equipment,when the radius of the emulsion explosive is 2 cm and the weight of RDX is 1 0 g,the smallest row spacing,which minimizes the effect of the emulsion explosive in the front row on that in the back row,is determined as 20 cm.Therefore,in order to decrease the experiment error,we can decide on the smallest row spacing through numerical simulation before the dynamic desensitization experiments take place.Our work can serve as a reference for the further research.关键词
