Abstract  

A new hydraulic hybrid excavator driving system was proposed concerning on the issues that the loss of energy was too large and the energy recovery efficiency was not high enough. The driving system used complex cylinders and accumulators to recover the potential energy of mechanical arms and load of the excavator. The complex cylinders were composed by three chambers, including chamber with pistonrod, chamber without pistonrod and counterweight chamber. The counterweight chambers were connected to accumulators, which provide average load force. The chambers with and without pistonrod were connected to entrance and outlet of the pump/motors, respectively, forming pump control systems. The hydraulic pump/motors charged chambers with pistonrod or chambers without pistonrod to drive the action of mechanical arms. The energy conservation effect was verified by simulation. The mathematical model was established to analysis the control performance, the dynamic and static relations among hydraulic components and the energy loss of the system. In addition, the energy management strategy based on instantaneous optimal control strategies was proposed. According to the simulation result and the analysis of mathematical model, the energy recovery efficiency of the mechanical arm is improved and the energy loss is reduced. The maximum output power of the engine can be reduced by 27%, and can be further reduced by 44% using energy management strategy.

油液混合动力挖掘机势能回收及能量管理策略

针对油液混合动力挖掘机能量损失较大、能量回收效率偏低等问题,提出基于复合液压缸和蓄能器的混合动力挖掘机机械臂势能回收系统.复合液压缸由有杆腔、无杆腔和配重腔3个容腔组成.配重腔与蓄能器相连,提供机械臂负载平均值；有杆腔和无杆腔分别与泵/马达的2个进出油口相连构成闭式系统,通过泵/马达向有杆腔或无杆腔提供高压油液从而驱动机械臂动作.通过仿真分析验证系统的节能效果；建立系统数学模型,分析系统控制性能和液压元件之间的动、静态关系及能量损耗；提出基于瞬时优化控制的能量管理策略.通过仿真及数学模型的分析结果表明,势能回收系统可以提高机械臂能量回收效率,减小能量损耗,发动机最大输出功率可以减小27%,通过能量管理策略可进一步将发动机最大输出功率减小44%.
