摘要结合跟踪仪动态性能校准的需要,根据跟踪仪的跟踪原理,研究了限制跟踪速度的主要因素。采用匀角速度旋转运动转换成匀线速度运动的原理,设计实现了跟踪仪动态性能校准装置。设计了相应的试验,在不同的设定转数条件下测试该装置的性能;在不同距离处对激光跟踪仪进行了动态性能的校准测试。测试结果显示,匀速转动时速度变动性符合预期,可用于激光跟踪仪动态性能校准。

Abstract：Calibration statuses of dynamic performances of laser tracker are summarized. According to basic principle, combined demands of dynamic performance of laser track and the limits of tracking speed are studied. The theory of uniform angular speed rotation transformed into uniform linear speed is adopted and calibration device for laser tracker dynamic performances is designed and assembled. The relevant tests are planned. This device is test under different revolution settings. Dynamic performances of laser tracker are tested under different distances with this device. Test results are analyzed. Experiences in test are summed up. Test results indicated that speed variability in uniform rotation is satisfying and could be used in dynamic performance calibration.

Key words： Metrology Laser tracker Dynamic performance Tracking speed Linear speed RMS
