The Design And Simulation Of The Parameters Matching Of The Power Assembly Of The Hybrid Bus

With the increasing demand for energy,the energy problem has gradually become a problem in today's society,and with the use of fossil fuels,resulting in more and more serious environmental pollution.More seriously,with the improvement of people's living standards,people rely on the degree of dependence on the car more and more high,with the acceleration of urbanization,but as a city traffic must be tools for the development of new energy bus has become today's bus research and development An important direction of this paper around the hybrid bus related issues related to carry out research.As the cost of pure electric bus and mileage is not very satisfactory,if you can effectively use the engine to generate electricity,to a certain extent,can achieve good economic and ecological benefits,so this paper from the hybrid structure and work mode Based on the comprehensive analysis of the hybrid powertrain system and the existing hybrid structure,a hybrid power system with double motor is proposed.The system can make the engine both be driven separately,Can also drive and power generation at the same time,the engine power output utilization to achieve the highest.For the proposed two-motor hybrid structure,by summing up the existing mixed power system parameter matching theory and method,combined with the theory and method of the characteristic matching of the hybrid system,the whole structure of the whole hybrid system: the engine,Motor,transmission,battery and so on the transmission system parameter matching and analysis,the hybrid power system structural simulation laid the foundation.Based on the structural characteristics of the hybrid vehicle,the AMESim simulation software is used to analyze the hybrid electric hybrid of the double motor.The AMESim is used to start the common module of the vehicle simulation from the basic part.At the same time,the hybrid system,The AMESim-based vehicle hybrid system assembly parameter matching model is established,and the motion model of the hybrid system is taken into account,and the vehicle control strategy is established.Under the NEDC condition,the economic and dynamic In order to verify the fuel economy of this structure,AmeSim established a pure fuel bus model in this paper,and carried out the same method.In order to verify the fuel economy of this structure,AmeSim established a pure fuel fuel bus model and carried out the same.In order to verify the fuel economy of this structure,The simulation results show that the proposed hybrid electric power assembly can improve 18%,and the research foundation has laid a theoretical foundation for further manufacture of double motor hybrid hybrid bus prototype.
