摘要
介绍了并联式液压混合动力系统制动能量回收的节能机理。通过建立车辆动力学模型,参照车辆及相关液压元器件实物的实际参数对AMESim模型进行了相应设置,对车辆制动过程和能量回收过程进行连续仿真分析,得到了相应的曲线。为验证仿真的正确性,在液压试验台架上进行了与仿真相对应的各不同工况的试验,试验结果与仿真结果基本吻合。通过分析仿真与试验结果误差产生的原因,可以得出:在制动时间较短、制动强度较低的条件下,并联式液压混合动力系统能量回收率较高,总体高于43.12%。同时试验结果验证了仿真模型的正确性,说明本文所建立的AMESim模型能够较为直观地分析并联式液压混合动力车辆的制动能量回收过程和效果。
The energy saving mechanism of the braking energy recovery system of Parallel Hydraulic Hybrid Vehicle(PHHV)is introduced.By the establishment of vehicle dynamics model,an AMESim model is set up correspondingly according to the actual parameters of the vehicle and its hydraulic components.Then,by simulation analysis of the vehicle braking and energy recovery,a corresponding curve is obtained. To verify the correctness of the simulation,experiments corresponding to different working conditions are carried out on a hydraulic experiment table.The experiment results are basically in agreement with the simulation results.By analyzing the causes of the error between the simulation and experiment,the following conclusions can be drawn.Under the conditions of shorter braking time and lower braking force,the energy recovery rate of the parallel hydraulic hybrid system is high,which is over 43.12%.The correctness of the simulation model isverified by experiment results.The AMESim model can be used to intuitively analyze the effect of braking energy recovery of PHHV.
