摘要: 混合动力技术已经成为液压挖掘机节能研究的重点,基于混合动力技术的能量回收方案也得到了广泛研究。基于普通挖掘机的回转机构的特点分析,设计了一种电机驱动回转能量回收方案。方案以电动/发电一体机液压回转代替液压马达驱动回转机构,超级电容器为储能单元,采用矢量控制算法实现电机的驱动和能量回收。仿真研究表明,该方案具有较好的能量回收效果。
Abstract: Hybrid technology has become the key technology to improve energy efficiency of hydraulic exca-vators. Based on it, several energy recovery schemes have been widely studied. After analyzing the characteristics of ordinary excavator slewing mechanism, a kind of motor-driven rotary energy recovery solutions has been introduced. It uses an electric motor instead of hydraulic motor to drive the slewing mechanism, and uses super-capacitor to be energy storage unit. Meanwhile, the vector control algorithm has been used to control the electric motor. Simulation results show that this solution could achieve good energy recovery efficiency.
