摘　　要：转台为惯性敏感器件和导航制导系统的性能测试、标定提供精确的空间坐标定位、精密的运动测试基准,转台轴系的倾角回转误差和位置精度是衡量转台性能的重要指标。本文采用的精密机械轴承的转台轴系由于轴套和滚珠运动周期不一致,会导致轴系倾角回转误差测试出现归零问题,进而影响转台重复测试精度。The turn table provides precise space position and motion test datum for the performance test and calibration of inertial sensors and navigation guidance system.The angular error motion and position accuracy of the shaft system are important index to measure the performance of the turn table.Due to the inconsistence between the axle sleeve and the ball movement period,the angular error motion test of the precision mechanical shafting used in this paper will not return to zero,which will affect the repetition of the turn table.

关 键 词：转台 双周期 倾角回转误差 位置精度
