The Safety Analysis of the Step-Press-Loading Charges

WANG Shu-Ping(Xi′an Modern Chemistry Research Institute,Xi′an 710065, China)  
The characteristic of charge structure in step-press-loading charge are introduced.The safety simulation test of high explosive with various density is proformed by a big impact loading unit and the experimental results are analyzed theoretically.The result shows that the ignition threshold value of the charge without defect is higher.For charges with defect, the more the void ratio,the higher the value,indicating that a higher quality charge can improve the safety of overload resistance of charge,the specific void ratio can enhance over-load capability,and the density distribution of steppress-loading is beneficial for safety of overload resistance of charge.
