The Matching Study On Pure Electric Vehicle Dynamic Performance Matching Design And Simulation Research Based On The Advisor

Electri vehicle use electricity to provide energy Instead of oil, it can achieve the goal of "zero emissions" and "low-noise".Considering the problem of energy supply and severe environmental pollution, the problem that is caused by energy supply and severe environmental pollution can be solved with the research and development of pure electric vehicle. Parameter matching of power system is one of the main contents of pure electric vehicle research and development, precise parameter matching has a great influence on the automobile’s power performance, it also has a significant effect on the endurance mileage.In this paper, based on the gasoline car,calculated for the power system according to the vehicle’s parameters and performance requirements. As a platform of the simulation software ADVISOR, the simulation models of all parts which make up the power system of pure electric vehicles(including motor, battery, the main reducer, differential, wheels and so on) are established, the whole performance of vehicle is simulated dynamically, such as dynamic performance and endurance mileage. The simulation results show the car’s performance and working performance of each part, verify the rationality of the design of power system parameters according to the result of the simulation of the dynamic performance compared with preset target. According to the comparison results of automobile power train parameters are further optimized, so that the automobile dynamic performance reaches the preset goals. Finally, analyzes the performance, dynamic performance and economic performance indicators of car all achieves the expected design goal, the work performance of transmission parts is good, can realize energy conservation and environmental protection requirements.According to research and verification of design parameters of the pure electric vehicle, providing a theoretical basis and reference for the electric vehicle to enhance the power and increase mileage that it can achieve.
