【Abstract】 The over-loaded problems of initiator have direct influence upon its security and reliability, esp. in the case of emission and dynamic impacts. The new technique to measure the dynamic over-loaded capability by Hopkinson bar device is presented. The numerical simulation of the technique is processed and a serial of solutions from the technique are confirmed. The feasibility of this experiment is proved, thus simulation can provides bases for constituting new evaluation methods of security and reliability to initiator.更多还原
