摘要:
为了使液压挖掘机达到节能的目的,提出基于蓄能器能量回收和正负流量相结合的变量泵控制的节能驱动方法.考虑到发动机倒拖、大惯性负载引起的反转问题,以及变量泵和负载的流量匹配等问题,研究驱动系统的控制策略.建立多种驱动系统的AMESim数学模型,并进行节能效果和操控性能的仿真研究.结果表明:该系统在防反转控制和防止发动机倒拖方面均具有良好的控制效果,而蓄能器的压力在第3个工作周期后进入平衡波动状态;相对原驱动系统,新型驱动系统最大节能效果大约为36%,能量回收系统的行程效率大约为24%.
Abstract:
Due to the environmental problems and energy crisis, the improvement on the efficiency of the excavator is highly demanded. A novel hydraulic energy-saving system is presented. The system is based on a pump control system and uses an accumulator as the energy recovery system in a novel configuration to recover the kinetic energy. Then, considering the engine motored, big inertia load caused by the reverse problem, and variable pump and the load flow matching problems, the control strategies on how to control the swing are presented. Thus, AMESim mathematical models of different control systems are established. Simulations are performed to evaluate the validity of the effectiveness of the control system. The results indicate that the designed system has good control effect in anti-reverse control and engine motored prevention aspects. And the pressure of the accumulator is in the balance fluctuation state after the third working cycle. Relative to the original driving system, the maximum energy-saving of the new driving system is about 36% and the round trip recovery efficiency is about 24%.
