Article Preview

The circular probable error is a little larger in the ground dynamic navigation test of the laser gyroscope Strap down inertial navigation system, so a better vibration damping system needs to be designed for SINS with laser gyro. Through analysis for the model of the vibration and the old vibration damping system, a new system of the double free degree be bring forwarded to reduce the response of random vibration on inertial navigation system. During the design, considering the installing plate is part of the vibration damping system and reckoning the inner space of the tactical missile carefully , using the finite element dynamic optimization method, a satisfactory installing plate and a damper with better dynamic characteristics is designed, then through ground vibration experiment and the designed of repetition parameter optimization, now the new vibration damping system can work effectively and the effect of vibration absorbing has achieved the requirement, it can be applied to the aircraft.
