  • The micro-disturbance of reaction wheel assembly (RWA) is a key factor which will affect the accuracy of spacecraft attitude control. To obtain the disturbance characteristics,the RWA disturbance was meaured,corresponding control methods and isolation systems were adopted to restrain them. The disturbance coupled with the nature frequency of test bed since the bandwidth of RWA disturbance was wide. Accelerance measurement method was used to express the effect which the test bed had on measure results. And the mechanical model of RWA was built, in order to obtain the pure disturbance of RWA. Two test beds with different rigidity were designed to measure the RWA disturbance. Amplification coefficient was used to modify the measure results. To acquire the disturbance without affect of test bed rigidity, and results from two equipments were compared. The results show that accelerance measurement combined with mechanical modeling method captures the affection of test bed rigidity on measured disturbance effectively.
