装载机的作业平稳性研究

Research of operating stability on the loader

作业平稳性是装载机工作装置设计的目标之一。在结合实例的基础上,分析并指出工作装置举升机构中,动臂回转角速度的变化是产生动载和导致不平稳的因素。为了提高作业平稳性建立了举升缸供油流量Q随动臂回转时间t的函数,并得出了相关结论。

The operational stability is design goal of the loader＇s working device too. On the base combined with example, the paper analysis and points that changing angular velocity of rotating movable arm in lifting mechanism is the factor of dynamic load and instability. In order to raise operational stability of working device, the changing law of oil flow Q as time t goes on movable arm rotary is established, and some relevant conclusions is obtained.
