【Abstract】 Based on Hopkinson pressure bar technology and device,dynamic inertia overload of initiator is determined by free style stress wave load for typical initiator. This technology and device can detect 30000g～250000g of overload factor.Using the Ls-dyna finite element program, the simulation and emulated results are in accordance with tested results.The technology has resolved the hard problems to simulate supper over loading environment of initiators.更多还原
