Outline
It is very important and instructive for us to further and accurately investigate the interaction between constitutes of explosive and formation mechanism of hot spots in explosive initiation, with the constitutive relation and equation of states in wide pressure zone. Compared with shock compression, magnetically driven quasi-isentropic compression (shockless compression) is a more effective method to research the dynamic behavior of un-reacted explosives in wide pressure zone. Based on the working principle of electro-magnetic force produced by large current, the shockless compression technique driven by magnetic force was first realized in domestic. By optimizing the loading electrodes and the parameters of explosive samples, and controlling the installation technology, a pressure of 5 GPa was realized in magnetically driven quasi-isentropic compression experiments. By means of the technique of laser displacement interferometer and the Lagrange data processing method, the particle velocities of the interface between JO-9159 explosive and LiF windows were measured, and from which the experimental isentropes of JO-9159 explosive were obtained. Compared with the results from references, the experimental isentrope of JO-9159 explosive is consistent with that of PBX9501 explosive.
