Researched On Dynamic System Matching Design And Simulation Of Small Electric Training Vehicles Based On Ground

Driving school training trade is one of the important part of road transport industry.Driving school training trade whether can adhere to scientific and technological innovation as the means, with energy saving and efficiency for industry development goals, for road transport industry in energy conservation and emission reduction work, will play a very important role. In the current driver training, drivertraining is more than 70 percent of the time in subjects training within the field, vehicle is low gears and slow in training,the engine lay to high fuel consumption and high pollution regional work, the engine is basically in idling process, fuel consumption and emission performance will worsen,training should not only consume large amounts of oil, increase the driver training costs, but also the surrounding environment caused great pollution, at the same time, to the sustainable development of driving school training and the energy conservation and emissions reduction of road transport industry bring adverse effects. Therefore, combining the characteristics of motor vehicle driver field training, lower the fuel consumption and emissions training of subject training, the important ways.of decreasing the cost and improving enterprise efficiency. In current,due to electric vehicle in the course of driving almost have no emissions, and can save petroleum energy etc,and get the favor of most vehicles producers. So changing fuel drivertraining into pure electric drivertraining is very considerable in practical significance and economic significance.This design bases on restructuring SANTANA LX to pure electric training vehicles, mainly do matching design for drive part and determined the type and size of motor and battery and the transmission ratio, then select DC motor made by Changzhou yang company and Lead-acid batteries produced by Mingtai company with market research and information access. And do the control scheme design. Then carry on the power performance simulation to the designed dynamic system components. The simulation results as follows:Vehicle for maximum speed is 44km/h, the maximum gradeabillity is 13.6% at the vehicle speed of 9.7km/h,this complies with the design requirements of the dynamic properties. At last do the dynamic performance testing to the designed vehicle in vehicle test ground, the test results as follows:Vehicle for maximum speed is 40.22km/h, the maximum gradeabillity is 12% at the vehicle speed of 8.7km/h,and the vehicle achieves the gradeabillity started at 12%.This results is accordance with the simulation results, which further shows the rationality of designed dynamic system.
