摘      要：The hybrid tracked vehicles(HTV)usually adopt series hybrid powertrain with extra steering mechanism,which has relatively low transmission efficiency and reduces the flexibility of structural *** overcome the disadvantages,a new kind of single-mode powertrain has been *** power-split hybrid powertrain is composed of three planetary gear(PG)sets connected to one engine,left and right track outputs,and three *** proposed powertrain can realize steering while going forward by controlling the output torque on each side without extra steering mechanism or steering *** to the diversity of the connection way between components and planetary gear sets,a rapid configuration design approach is proposed for the design selection of *** automated dynamic modelling method can show the one-to-one correspondence with the selected feasible groups by establishing two characteristic matrices,which is more simple than other *** analytically-based method is proposed to classify all possible connection designs into several groups to decrease the searching scope with improved design ***,the optimal control strategy is used to find the design with optimal fuel economy under typical condition of *** case study is implemented by the proposed design approach which demonstrates better design performances compared with the existing series-hybrid HTV.
