摘要:

为改善液压挖掘机动力系统因负载波动剧烈而导致的发动机效率低下,提出一种以蓄能器为储能装置,配合液压二次元件为辅助动力源的功率差值补偿式油液混合动力系统.辅助动力源实时补偿发动机目标工作点功率与时变工作液压系统负载功率差值.针对此系统,提出一种结合负载预测和发动机转速稳定PI控制的控制策略;采用一种实用的负载扭矩计算方法来进行负载预测,并以蓄能器压力与工作液压系统实际状况为依据来控制辅助动力源,使发动机稳定工作于高效燃油区.AMESIM仿真与试验研究表明:相较普通液压挖掘机系统,带有此混合动力系统的挖掘机发动机转速波动范围减小了20%~40%,有效提高了发动机的燃油效率.

Abstract:

In hydraulic excavator, in order to improve the low energy efficiency caused by complex working conditions and load fluctuation, a kind of parallel hydraulic hybrid system with power compensation is proposed. This hydraulic hybrid system utilizes hydraulic accumulator as the energy storage device and hydraulic pumpmotor as secondary component, to compensate the power difference between target engine power and load power fluctuation online. Based on the proposed system, a control method consists of PI control and load prediction was introduced to stabilize the engine working point in high fuel efficiency area. A practical torque calculation method for load prediction was applied, as well as a strategy to adjust engine working points via assistant power source based on accumulator pressure and realistic working condition. Simulation in AMESIM and experiments are carried out in this paper. The results show that, compared with traditional hydraulic excavator, the engine speed fluctuation is decreased by 20%-40%, and the fuel economy is improved.
