摘要
同其他几种能量储存方式的制动能量再生系统相比,液压式储能具有最大的功率密度,适用于公交车的频繁制动、启动情况,在公交车液压式制动能量再生系统的设计中,首先要确定蓄能器、液压泵/马达排量和附加传动比这些参数。对蓄能器的参数,主要是以较少的容积储存较多的能量为约束进行计算。液压泵/马达排量和附加传动比这两个参数通过仿真计算确定。仿真表明所选的参数可以将公交车在5.2s内制动停止,平均减加速度为1.62m/s2,满足公交车的一般进站制动性能要求。
The Hydraulic braking energy regeneration system has the maximum power density com-pared with several other energy storage ways,which is suitable for the situation of the bus frequently braking and starting.In the design of the bus hydraulic braking energy regenerative system,these parameters such as delivery capacity of accumulator,hydraulic pump/motor,and additional transmission ratio should be confirmed firstly.With the constraint of depositing more energy in less capacity,the parameter of accumulator is comput-ed,while the parameters such as delivery capacity of hydraulic pump/motor,and additional transmission ratio is determined by simulation.The simulation result shows that the selected parameters can make bus brake in 5.2s,which average deceleration and acceleration is 1.62m/s 2,and meet the brake performance of bus.
