摘要
三轴模拟转台是进行飞行器飞行姿态地面半实物仿真系统的重要设备之一,其精度直接决定了仿真试验的置信度。通过分析转台动态响应能力并结合转台的部分实测数据,求解了转台动态误差系数,得到转台动态误差的计算公式,最后用一个典型仿真试验对三轴模拟转台动态误差进行计算分析。利用该动态误差计算公式得到的仿真结果可以为射频仿真试验设计及精度分析提供参考。
The three- axis simulation rotating platform is one of the key devices for the hardware- in- the- loop simulation test of the flight attitude of the aircraft on the ground, and its precision directly decides the con- fidence of the simulation test. Firstly, the dynamic error coeglcient of the rotating platform is worked out by analysing the dynamic response capability of the rotating platform with some actually- measured data from it. Then a formula is derived for calculating the dynamic error of the rotating platform. Finally, the dynamic errors of the three - axis simulation rotating platform are calculated and analysed based on a typical simulation test. The simulation results obtained from above formula for dynamic error calculation can be used for reference pur- poses in RF simulation test design and its precision analysis.
