Impact load driven by high-power pulsed electromagnetic force

Impact load is applicable to material science and engineering. With the research development, there is a higher requirement for the impacting velocity and energy, which are however beyond what the drop hammer can achieve. High-power pulse current can therefore be utilized to set up an intense pulsed magnetic field, and then high-power pulsed electromagnetic force (EMF) can be generated with proper equipments and converted to the impact load desired. In the present work we simulated the generation of the impact load driven by high-power electromagnetic force. The simulation results of high-power pulsed magnetic field, EMF and the punch movement process were obtained through numerical modeling. The high speed photography was used to record the movement of the compressing impact device. Through the image processing, the value of the impact velocity and impact energy is obtained that verified the simulation results.
