摘　　要：根据蓄能器优化条件阐述了液驱混合动力车辆的优化结构及其工作原理。建立了液压变压器瞬时流量的数学模型,用频率法进行了并联、串联式蓄能器的理论分析。当配流盘控制角不同时,对液压变压器各个腰型槽口的瞬时流量以及蓄能器的流量响应情况进行了仿真分析。结果表明,无论配流盘控制角是否为零,串联式蓄能器的脉动衰减作用优于并联式蓄能器。The optimal structure of the hydraulic hybrid vehicle and its working principle were presented based on the optimization conditions of the accumulator.A mathematical model was built for the instantaneous flow rate of the hydraulic transformer（HT） and the theoretical analyses of the series and parallel accumulator were made with the frequency method.The instantaneous flow rate through the kidney form port of the HT and the flow rate response of the accumulator were numerically simulated under different control angle of the port plate.The results show that the damping effect of the series accumulator to the flow pulsation of the HT is superior to that of the parallel accumulator,regardless of the control angle of the port plate is zero or not.
