Parameter Matching and Performance Simulation of Hybrid Road-rail Towing Tractor Power System Based on Degree of Hybridization

针对混合动力公铁牵引车的运行特点及性能指标要求,对其混合动力系统参数进行匹配。运用混合度设计方法,确定混合动力系统混合度的上下限值。通过对汽车仿真软件Advisor的二次开发,建立该车仿真模型,对不同混合度下的动力系统参数进行仿真。仿真结果表明,在混合度为42%时,整车动力性、经济性均符合设计要求。

The paper matche9 the parameters of hybrid system according to the operating characteristics and performance requirements of hybrid road-rail towing tractor. Firstly, it determines the upper and lower limits of hybrid system with the design method of DOH （ degree of hybridization ）. Then, it establishes a simulation model by re-developing the simulation software Advisor and simulates power system parameters in different degree of hybridization, The simulation result shows that the dynamic property and economy of the vehicle can meet the design requirements at the 42% degree of hybridization.
