摘 要: 温度性能是制约陀螺精度等性能的一个主要因素,在各类陀螺技术的研究中都备受关注。温度因素对固体波动陀螺性能的影响主要体现在陀螺的测量精度以及零偏,究其根本原因是温度变化对金属振子的振动特性产生了影响。本文分别从理论推导、仿真分析和实验测试方面研究了温度对金属振子振动特性的影响行为,为解决温度对固体波动陀螺性能影响的改善提供了一种新途径。 Temperature is a major factor restricting the gyro’s accuracy and other performance,thus it is concerned in the study of various types of gyro technology.Effects of temperature on the solid wave gyro mainly reflect in the gyro bias and measurement accuracy,and the fundamental reason is that the changes of temperature have an impact on the vibration characteristics of the metal resonator.This paper studied the effects of temperature on the vibration characteristics of the metal resonator through the combination of theory,simulation and test.A new way to improve the gyro’s performance under temperature is provided.
