摘要
半球谐振子是半球谐振陀螺的关键组成部件,而其性能参数是制造高精度半球谐振陀螺的关键,针对谐振子加工后表面的复杂结构、多种缺陷层和球壳质量不平衡,讨论化学处理工艺和离子束调平技术对谐振子主要性能参数品质因数和频差的优化。实验结果表明该工艺技术效果显著。
The hemispherical resonator is the crucial part of hemispherical resonator gyroscope （HRG）, and itsr performance parameters are the key factors of fabricating the hemispherical resonator gyroscope with high accuracy. Aiming at the complex structure, multi-layers defective and mass-unbalance of the shell, the optimization of two main parameters of hemispherical resonator： the Q-factor and the frequency diversity, by using the chemical treat- ment technique and the ion-beam balancing technology is discussed in this paper. The experimental results show that the techniques have significant effectiveness.
