The performance of a micro inertial measurement unit（MIMU） based on resonant gyroscope is influenced by external and internal vibration interference.On the basis of analyzing vibration sources and disadvantages of traditional vibration attenuation methods

a new damping solution based on damping alloy and design of MIMU structure is proposed.Simulation experiments are designed to analyze the mechanical properties and damping attenuation characteristics.Results show that the solution based on damping alloy can meet requirements of the system

and it has good vibration attenuation and anti-interference ability.
