Research on Dynamic Ignition Efficiency of Mortar Based on Magnetically Coupled Resonance
In order to study the dynamic ignition efficiency of the mortar with magnetic coupling reso-nance,the system transmission efficiency η and the total ignition energy Q were taken as the factors to characterize the ignition efficiency.A mathematical model of magnetic coupling resonance wireless energy transmission was established,identifying mutual inductance M,primary coil height H,and secon-dary coil motion speed v as crucial factors influencing ignition efficiency.Maxwell simulation was used to analyze the influence of motion state,travel and speed on the firing efficiency of mortar.The research findings indicate that the motion state has a significant impact on ignition efficiency,with mu-tual inductance,transmission efficiency,and total ignition energy being higher in static conditions compared to dynamic ones.The pitch and number of turns of the primary coil determine the motion stroke,where more coil turns lead to higher transmission efficiency and lower total ignition energy.Mo-reover,larger coil pitches result in higher total ignition energy,while transmission efficiency peaks at a pitch of 5.5 mm.When the secondary coil moves at a constant speed of 5～20 m/s,transmission effi-ciency remains relatively stable with increasing speed,resulting in a decrease in total ignition energy.Furthermore,the influence of increased speed on total ignition energy gradually diminishes.
