Abstract:The driving scheme of a 400 - 1 000 km/h high speed test vehicle based on reconnection electromag- netic launch was studied. The circuit structure and the motion equation of reeonnection electromagnetic drive were discussed. A drive system simulation model was built in the Maxwell3D transient field. The mechanical characteristics and accelating rules of level 3 drive system were investigated under different initial velocities. Ac- cording to the system motion characteristics and efficiency problems, driving circuit optimization scheme was pro- posed, which can improve the motion charaeterstics of launch objects and the efficiency. The simulation results show that, the super high speed test vehicle which applies reeonnection electromagnetic driving, can be acceler- ated to the target of high speed in a short period of time through the rational allocation of the drive unit.
Keywords:super high speed test vehicle  electromagnetic drive  multi - stage reconnection drive  maxwell 3D transient field simulation
