| Abstract: |
| The three-axis simulation rotating platform is one of the key devices for the ha
rdware-in-the-loop simulation test of the flight attitude of the aircraft on the
ground, and its precision directly decides the confidence of the simulation tes
t. Firstly，the dynamic error coefficient 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 d
ynamic 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 purposes in RF simulation test desi
gn and its precision analysis. |
