运用数学方式对大型曲臂式高空作业平台的变幅调平机构几何参数进行求解,并分析不同时刻作业平台与地面之间的水平误差,证明变幅系统组合使用时,造成误差的原因不仅与机械结构的选择有关,同样与液压系统的流量和运动速度有关。
The geometrical parameters of the luffing and leveling mechanism of a large-scale boom-type aerial work platform are solved mathematically and the horizontal errors between the work platform and the ground at different moments are analyzed. It is proved that the reasons for the errors when combined with the luffing system are not only related to The choice of mechanical structure is also related to the flow and speed of the hydraulic system.
