Gave a test method of the dynamic characteristics about gyroscope. In the process of using Gyroscope, it will be affected by various external factors irresistibly in making the gyroscope working at certain vibration frequency. Designed the experiments of steel plate vibrating to examine the relationship between the sensitive angular rate of gyroscope and vibration frequency. Firstly, fixed the plate on the desk; then made the plate to vibrate, collected the data from the gyroscope which vibrating with steel plate. To analyze the data of collection, gained the dynamic characteristics of gyroscope. In addition, designed rotating floor calibration experiment, calibrated the relationship between input and output of gyroscope and verified the rationality of the steel plate vibrating experiment. The result prove that gain the dynamic characteristics of gyroscope by steel plate vibrating, not only the method is simple but the result also can achieve the good precision.
