Parameter Design of Multi-axis Series Hybrid Electric Vehicle

The series hybrid multi-axis heavy-duty special vehicle is focused.The rationality of hybrid power parameter matching determines the potential of vehicle power source,the degree of synergy between electromechanical subsystems and key technical indicators such as power performance,economy and reliability meeting the requirements.In order to improve overall performance of the vehicle,it is necessary to optimize the subsystems in the initial design stage.Based on the research experience at home and abroad,the vehicle boundary constraints from the performance requirements are calculated and analyzed,the important parameters of the vehicle are optimized,and a reasonable matching system is formed for the hybrid electric vehicle parameters to improve the accuracy of matching results.Finally,the rationality of the parameters matching method is proved by the typical cyclic condition simulation.
