Instrumental inspection of vibration disturbance forces and moments generated by reaction wheels is an actual technical problem. Dynamic accuracy of the space vehicle for the Earth observation and small space vehicle depend on the level of vibration disturbance forces and moments generated by working onboard devices such as reaction wheels. To reducing of vibration disturbances and to check disturbance forces and moments caused by the unbalance of rotating parts of reaction flywheels the special force measuring stand has been developed. The stand consists of the measurement module, converting and recording parts. Stand operation principle is based on real-time measuring the projections of forces created by working reaction wheel on three orthogonal axes X, Y, Z. The special method of calculating the disturbance moments using values of the forces obtained experimentally has been proposed. The method of determining disturbance moments implemented in specially designed software of the stand is proposed.
