摘　　要：针对目前普通挖掘机上存在的动臂、斗杆和铲斗下降后,因势能无法回收而造成的能量损失以及由此而引起的液压元器件发热、失效、加速磨损等问题,在设计混合动力挖掘机时,提出了一种由液压缸、节流阀、变量马达和发电机组成的挖掘机势能回收系统,并将回收的能量纳入整机能量分配管理系统中。该回收系统回收效率较高,可控性好,能有效延长元器件寿命,并在一定程度上降低发动机装机容量,达到了节能的目的。To solve the problems such as components fever, failure and wearing out that are caused by wasted potential energy when the boom, arm, and bucket of general excavator fall down, an energy recovery system made up of cylinder, throttle, variable motor and generator was proposed to be used in hybrid excavator, and all the energy recovered will be in the charge of energy distribu- tion management system. The simulation results indicate that the system has high recovery efficiency, good controllability, so it helps to extend the life of the components, reduce the engine capacity, achieve energy saving.
