Measurement and Analysis of Shock Wave Overpressure of Thermal Explosion of Charge with Shell

The explosive shock wave pressure is an important parameter which is used for the evaluation of explosion effect,and the characteristic of shock wave pressure is closely related to charge and detonation mode.A measurement method and the results of overpressure of charge with shell measured in the case of thermal explosion were described,and the results were analyzed according to the structure of explosive cave.The results show that the electromagnetic radiation is emitted due to the electrokinetic effect and the friction between explosion product and shell when the charge explodes,and the signal duration and complexity of electromagnetic radiation generated by the charge with shell are different from those generated by the bare charge.
