Vibration Effects Analysis of IMU by Transfer Matrix Method for Multibody System

摘要：

　　The output accuracy of inertial measurement unit(IMU)is low under dynamic vibration environments.The damping multibody system dynamics model of IMU was established by transfer matrix method for multibody system,and the steady-state response of IMU was solved under vibration in this paper.Combined with the attitude angular velocity calculation error formula,the attitude angular velocity calculation errors were analyzed under different sinusoidal vibration environments.The simulation results show that the attitude errors analysis of IMU and damping structural parameters design of IMU under sinusoidal vibration environments are effective.It provides a reference means that improve the dynamical performance of IMU under vibration environments.This method can be further extended for velocity and position errors analysis caused by IMU vibration.
