| 摘 要： | 在对虚拟轴机床进行运动学标定的仿真计算过程中 ,采用间接测量法对虚拟轴机床的运动进行间接测量 ,然后通过矩阵重构的方法来解决测量噪声的干扰问题。仿真结果表明 ,虽然在虚轴机床的工作空间里无法将其可能存在的结构误差全部求出来 ,但计算结果完全可以满足机床在工作空间里的运动精度要求。因此采用此方法对虚拟轴机床进行标定是可行的

| Abstract: | During simulation of kinematic calibration of virtual axis machine tool, indirect method is used for measuring its position and orientation; meanwhile Jacobean matrix regrouping method is used instead of arduous optimization to avoid measurement noise maginification. Simulation result shows that although all structural error of virtual axis machine tool can not be identified completely while the moving platform moves inside its working space, the moving platform kinematic accuracy is fulfilled inside the whole working space after error compensation. It shows that the method for calibration is feasible. |
