摘要

The precision of the laser gyro used in tactical missiles is poor because of dithering frequency, actuating by vibration, shock and overload in dynamical environment. This paper introduces the transfer matrix method of the multibody system (MSTMM), establishes the dynamic model of the laser gyro strapdown inertial measure assembly aseismatic system, and analyzes the precision affected by dithering of the laser gyro and shocking of the tactical missile. And the dynamic response of the laser gyro strapdown inertial measure assembly aseismatic system is obtained by simulating the multibody system model. The simulation result indicates a theoretical idea to design the vibration isolation for the laser gyro strapdown inertial measure assembly.
