| 摘要: |
| 为测量五轴台的轴线垂直度、相交度以及对准误差,首先介绍了用水平仪测量非整周回转竖直轴系铅垂度的测试原理,及利用经纬仪将回转轴线引出的原理．在测量了三轴转台偏航轴、双轴转台偏航轴的铅垂度基础上,通过安装调整经纬仪的位姿,建立固联在经纬仪上的基准坐标系．在三轴转台的俯仰轴端安装十字靶标A、B,滚转轴端安装靶标C、D,在双轴转台的俯仰轴端安装靶标E、F．利用经纬仪将这3条轴的轴线分别引出．在三轴转台和双轴转台偏航轴端安装细丝S3和S2,用经纬仪将两偏航轴轴线某点引出．最后根据引出的3条轴线与两偏航轴轴线上两点,得出了五轴台的垂直度、相交度和对准误差．最后对垂直度、相交度、对准的测试误差进行了相应的误差分析,证明本测试方法能够满足精度要求． |

| Abstract: |
| In order to measure the axis perpendicularities, axis intersections, and alignment errors of five-axis simulator, the measuring principle of vertical axis′s perpendicularity vs. horizontal plane and the way of leading to rotation axis line with a theodolite and crosshair targets or filaments was introduced, in which the vertical axis system cannot rotate in full circle. Based on the measurement of the plumb errors of yaw axis lines of the three-axis simulators and the two-axis simulator, then an elementary coordinate system fixed on the theodolite was established by adjusting the pose of theodolite. By fixing crosshair targets A and B on the two ends of pitch axis of three-axis simulator, C and D on roll axis of 3-axis simulator, E and F on pitch axis of two-axis simulator, these three axis lines were led to by theodolite and crosshair targets. Then S3 and S2 filaments were mounted on the ends of two yaw axes of 3-axis and 2-axis turntables′, and two points on these two yaw axis lines were also led to by two theodolites. Finally the perpendicularities, axis intersections and alignment errors are achieved by the leading axis lines or points on the axis lines. Accordingly, the measurement error analysis is conducted and the validation of this method is achieved. |
