针对发电机式制动能量回收系统仅能应用于新能源汽车的缺点,提出了一种可应用于传统汽车的飞轮式汽车制动能量回收系统。设计了该系统的机械结构,阐释了它的工作原理;在Matlab-Simulink环境下建立了该系统的仿真模型,对它的工作原理以及影响制动能量回收效率的主要结构参数—电磁离合器最大转矩、储能飞轮传动比及储能飞轮转动惯量进行了仿真计算。仿真结果表明,在NEDC循环工况下,该系统能有效回收10%~14%的制动能量。研究结果可以为飞轮式汽车制动能量回收系统的开发和应用提供参考。
In view of the shortcoming that regenerative braking energy recovery system can only be applied to new energy vehicles, a flywheel vehicle braking energy recovery system that can be applied to traditional vehicles is proposed. The mechanical structure of the system is designed and its working principle is illustrated. The simulation model of the system is established under the environment of Matlab-Simulink. The working principle of the system and the main structural parameters influencing the braking energy recovery efficiency are discussed. Moment, energy storage flywheel transmission ratio and energy storage flywheel moment of inertia were simulated. The simulation results show that the system can effectively recover 10% ~ 14% of braking energy under the condition of NEDC cycle. The research results can provide a reference for the development and application of flywheel vehicle braking energy recovery system.
