    RESEARCHES ON DESIGNING OF MEMS STRAPDOWN INERTIAL NAVIGATION VIBRATION DAMPING SYSTEM by DUAN ZhenYu, CHU HaiRong, JIA HongGuang, WANG YuTing

    Published 2017-01-01
    “…To efficiently design damping system of MEMS Strapdown Inertial Navigation System(SINS) which performs well on vibration attenuation,a method to design vibration damping system of MEMS SINS according to transfer function and performance demand were present.First the design of supporter and the assign of vibration damping devices were finished.Then through sine scanning vibration experiment,the amplitude-frequency characteristic curves of the each inertial device in MEMS SINS were obtained,and the vibration damping goal for each inertial device in MEMS SINS were got through the study these curves.At last the amplitude-frequency characteristic curves of the accelerator that sensitive the vibration direction were simulated under logarithmic coordinates,and the design were finished according to outputs requirement.Simulation through MATLAB indicate,after vibration attenuate,designed system perform well in meeting the requirements for outputs of MEMS SINS,meanwhile it decreased the output deviations of three MEMS gyroscope.Simulation indicate,for the vibration damping problem of MEMS SINS,well performed vibration attenuation system can be quickly designed under the output requirement for MEMS SINS through this way.…”
