Abstract :
Method of identifying the dynamic model of accelerometer on precision centrifuge is studied in this paper. Through the method of improved Levy´s identification, using only the accelerometer magnitude frequency response data, the accelerometer´s dynamic mathematical model can be identified expressed in transfer function. The practicability and effectiveness of the method is illustrated by means of experiment
