摘要：
An important way to improve the dynamical test accuracy of an inertial measurement unit (IMU) is to suppress its vibration. In this paper, the dynamics model of a laser gyro strapdown IMU is developed based on the new version of the transfer matrix method for multibody systems (MSTMM). According to the dynamics model, acceleration responses of the IMU system with and without control are numerically computed under random excitation. The results show that the work situation of the IMU can be significantly improved by adopting magnetorheological elastomer (MRE) isolators, which provides a new technical means of upgrading the output precision of IMU.
