摘　　要：为了改善采伐机的动力系统,以庞塞FOX采伐机为设计蓝本,结合串联式混合动力系统,确立了混合动力林木联合采伐机底盘动力系统的设计参数;利用动力学计算混合动力系统的动力元件参数,根据参数对动力元件进行选型;借助AVL Cruise软件建立动力系统的模型,并仿真分析,对比混合动力林木联合采伐机动力系统和传统动力系统的行驶性能,得到混合动力系统,提高了采伐机的最大速度,减小了加速时间;表明利用混合动力系统能很好的改善林木联合采伐机的动力性。In order to improve the dynamic system of tree harvester,the design parameters of chassis dynamic system for hybrid tree harvester were established based on the Ponce FOX harvester and the series hybrid dynamic system. The dynamic component parameters of the dynamic system are calculated with the dynamic formula to get the parameters of the key components and type selection.It is established and simulated analysis that the model of drive system with the aid of AVL Cruise software,which compared with the driving performance of the hybrid tree harvester and the traditional dynamic system,and obtained that the hybrid system increases the maximum speed and reduce the acceleration time of tree harvester. It shows that the dynamic performance of tree harvester can be improved in the hybrid dynamic system.
