The method of adding inclination sensor on the different position of the concrete pumps' boom to detect the boom' s Flexible deformation and level variation is described, what's more, the method to make up for the Theoretical error is particular analyzed. The Practical application test proved that the boom's position accuracy has been improved more than 75%.%针对在利用倾角传感器实现混凝土泵车之类的大型操作机的臂架姿态的间接测量方案中存在的因为臂架的柔性和操作机在不同姿态下自身水平状态的不同可能导致的臂架末端的理论计算值存在较大测量误差的问题,采用了一种在臂架的不同位置增加传感器来实现对臂架柔性变形大小和自身水平状态的实时检测的方法,并着重研究了针对具体的柔性变形及水平状态变化所导致的理论偏差进行实时补偿的切实可行的方法,实验检测的数据证明,相对补偿前臂架的定位精度提升了75％以上.
