摘要
挖掘机最常见工况为挖掘循环,在挖掘循环中各执行部件的协调性是挖掘机操控性的重要指标。文章通过对各部件协同工作控制方式的研究,提出一种带有动臂下降复合动作的协调性优化控制策略,通过工况识别及基于动臂下降先导压力的前馈控制,对动作相关阀芯进行控制,实现带有动臂下降的复合动作的协调控制,同时降低冲击度。
The most common working condition of excavators is the excavation cycle,in which the coordination of various executive components is an important indicator of excavator controllability.Based on the research on the cooperative work control mode of various components,this paper proposes a coordinated optimization control strategy for the composite action with boom falling.Through the recognition of working conditions and the feedforward control based on the pilot pressure of boom falling,the action-related spool is controlled to realize the coordinated control of the composite action with boom falling and reduce the impact.
