Abstract
Gyrowheel is an integrated servo device which is applied as both sensor and actuator in micro-spacecraft. In practice, the undesirable mechannical factors generated from manufacturing could effect the accuracy of measurement and actuating, so it is necessary to analyze these undesirable effects on Gyrowheel for diagnosing the kind of mechannical errors even providing a sort of restraining method. In this paper, two common undesirable mechannical factors, the friction of the universal joint cross and the dynamic unbalance of rotor, are described in the Gyrowheel model built by Matlab/SimMechanics. The tilt angles response of the rotor in both time and frequency domains are developed in this paper, which provides simulation foundation and error analysis criterion for Gyrowheel prototype testing.
