【Abstract】 In this paper,based on Hopkinson Pressure Bar technology and device,dynamic inertia overload of initiaor is determined by free style stress wave load for typical initiator. This technology and device can detect 30000g～250000g of overload factor. In this paper,based on Ls-dyna finite element program, the emulation is applied. The 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
