Abstract:

As the main tools of highway transportation,vehicles have a profound influence on environment and traffic.Because the existing vehicle modification technology lacks the corresponding matching research and dynamics simulation analysis,this paper proposes a method for vehicle modification through the corresponding parameters matching and dynamics simulation analysis.The modification of LS6600C type ordinary medium bus and the parameters matching design of power system are discussed.We adopt the vehicle simulation software ADVISOR to establish the corresponding pure electric vehicle power system and the simulation model of the vehicle.The highest speed,acceleration,climbing performance of the vehicle model are simulated and researched.The results show that the continue driving range,maximum speed,accelerating performance and climbing performance of the modified vehicle can satisfy ordinary medium bus operation requirements and service conditions,and this modification technology has a broad prospect application.
