Dynamic Balance Test System of Gyro-rotor Based on Torque Feedback Method
Aiming at the performance problem of gyro-rotor of the gyroscope,a dynamic balance test system of the gyro-rotor is designed. A touch-screen integrated computer is applied as the upper computer,and the lower computer is composed of hardware circuit,vibration sensor,photoelectric sensor,USB2811 data acquisition card,etc. Based on the principle of torque feedback method,the amplitude and phase angle in the vibration signal are calculated by Visual Basic programming,and rotor phase and unbalance value are calculated according to the relevant principle of influence coefficient method,so as to determine the radial offset value of the mass center of the gyro-rotor. A theoretical model is established to verify the stability and measurement accuracy of the gyro-rotor high-speed dynamic balance test system .
