摘　　要：介绍了复合动力系统的概念、功能、结构和特点,分析了将复合动力应用于挖掘机类产品的必要性和开发的着眼点。在一个自行开发的3.5t挖掘机器人虚拟样机上进行仿真试验,研究在挖掘机上进行能量回收的潜力以及将复合动力应用于挖掘机的可行性和经济性。通过仿真试验分析,得知若把所有回收能量充分利用起来,可以节省大约40%的能量消耗。介绍了日本神钢公司应用复合动力技术的挖掘机样机,实例证明:能量回收利用可明显降低油耗。Concept, functions, structures and features of combined power system are described. Necessity to apply combined power to excavator products and its development consideration are discussed. Simulation is conducted on virtual prototype of a self-developed 3.5t excavating robot to research the potentiality of power reclaiming on excavators and the feasibility and economy to apply combined power to excavators. From the simulation analysis, it is concluded that 40% power consumption will be saved if all reclaimed power can be fully utilized. A prototype of an excavator with combined power technology from Japan Kobelco is presented to verify the significant decrease of fuel consumption through power reclaiming.
