摘　　要：针对传统挖掘机回转能量损失,提出了一种辅助动力式油液混合动力挖掘机回转能量回收系统,通过仿真的方法与直接动力式系统进行了比较研究。结果表明,直接动力式系统的能量释放过程可使马达入口压力产生较大的波动,需要对挖掘机原液压系统做较大的改动;而辅助动力式系统的能量释放过程平稳、独立,实用性更好。Aiming at the loss of gyrating energy in traditional hydraulic excavators, a system recovering gyrating energy of the hydraulic hybrid excavator with assistant power was proposed. The system was compared with the direct power system by simulation. The results showed： the energy released by the direct power system caused great pressure fluctuation at the motor inlet, so the hydraulic system of the excavator needed to change greatly; while the assistant power system released the energy stably and independently, thus had better practicability.
