摘要

基于谐振式MEMS陀螺的微惯性测量单元（MIMU）

在工作时其性能会受到来自内部与外部振动干扰的影响。在分析了影响MIMU性能的振动来源和传统减振方式的不足的基础上

提出一种基于阻尼合金的新型减振方案和相应的MIMU结构设计

并设计了仿真实验分析其力学性能和阻尼衰减特性。结果表明:采用该阻尼合金的方案

MIMU减振结构的各项力学指标均符合要求

并且具有良好的减振抗干扰特性。

Abstract

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.
