Dynamic Characteristic Analysis and Anti Vibration Design for Gyro Component

The problem of the random response of a certain type of inertial attitude sensor in the structural design of the gyro component is analyzed. The dynamic model of the structure of the gyroscope is established. The vibration response of the top head is solved by installing the metal rubber shock absorber and reasonably arranging the damping material with damping ratio in the structure. The results of vibration test and numerical simulation show that, the application of metal rubber damper and damping structure can significantly reduce the response of gyro under the environmental conditions of high frequency random vibration, and can improve the reliability of the gyro during the launch stage.
