三坐标划线仪的回程误差分析与改进

Improving and analysis of the accuracy for three-coordinate plotting measures

基于汽车转向轮的力学原理,着重以力学分析方法分析三坐标划线仪的机械结构产生回程误差的原因,并提出了改进仪器运动部件的新结构,从而提高三坐标划线仪整体的精度。

The problem about improving the accuracy of three-coordinate plotting measures has been studied. The error source in the machine construction is analyzed mainly by the mechanics.The new construction of moving parts in the instrument has been designed, and the accuracy of three-coordinate plotting measures could be improved.
