Abstract

Frequency splitting occurs between the degenerate modes of MEMS ring gyroscopes due to manufacturing errors, which severely restricts their performance. This letter presents a frequency split tuning method based on Joule heating in a fused silica inductive vibrating ring gyroscope. A specially designed wire layout generates a temperature gradient on the resonant structure when current flows through, causing different frequency shifts in the two degenerate modes, thus achieving frequency split tuning. This method successfully enabled mode matching for a gyroscope with an initial frequency split of 1.47 Hz, demonstrating a frequency split tuning capability of 58 Hz/W.[2025-0075]

熔融硅电感振动环陀螺仪的焦耳加热分频调谐

由于制造误差，MEMS环形陀螺仪的简并模之间会产生频裂，严重制约了其性能。本文介绍了一种基于焦耳加热的熔融硅电感振动环陀螺仪的分频调谐方法。特殊设计的导线布局在电流流过时在谐振结构上产生温度梯度，使两种简并模式发生不同的频移，从而实现分频调谐。该方法成功地实现了初始分频为1.47 Hz的陀螺仪的模式匹配，证明了分频调谐能力为58 Hz/ w。[2025-0075]
