| Abstract: | In order to separate the disturbance signal of the external vibration from dynamic balance measuring signal of the precision centrifuge, this paper analyzes the measuring signal of dynamic balance measurement system of the precision centrifuge(the inertial navigation test equipment), the rotary center of the rotor acted by the static unbalance and the couple unbalance is studied respectively, the horizontal external vibration from the foundation and the effects of angle vibration on the dynamic measurement are studied respectively. The requirements for external vibration is put forward by means of signal to noise ratio of dynamic balance measuring system. |
