Abstract: A new dual-motor driving system configuration was proposed to increase energy usage for pure electric explosion-proof rubber tire vehicle in mine, and the saving energy mechanism of dual-motor driving system was analyzed, and the principle of the configuration parameter matching and the curve of motor equivalent external characteristic were formulated. At the same time, the optimal driving mode of dual motor drive system was calculated by the principle of minimum electric power consumption, and the threshold value of each mode was identified. The simulation model for single motor driving system and dual-motor driving system were builded by using MATLAB/Simulink, energy consumption and driving range at cruise conditions were simulation calculated in auxiliary transport roadway of Wang jia Ling underground , the simulation calculation results show that dual-motor driving system can achieve a better economic performance.
