摘　　要：金属谐振子哥氏振动陀螺温度灵敏度高的原因是谐振子的品质因数(Q值)低。现代冶金技术可提供在温度变化时高稳定性和高Q值的合金,为实现高精度金属振动陀螺(CVG)打下了基础。通过从大量的合金材料中筛选符合金属振动陀螺要求的特殊材料进行研究与分析,并探讨了不同热处理工艺对材料性能、金属陀螺谐振子性能参数等的影响。实验结果表明,马氏体时效钢3J33对金属振动陀螺谐振子的性能参数优化有较好的效果。The metallic resonator Coriolis vibratory gyroscope(CVG) has high temperature sensitivity duo to the low Q -factor of the resonator.Modern metallurgical technology can provide alloys with high stability and high Q at temperature change,which lays a foundation for realizing high precision metallic resonator Coriolis vibration gyroscope(CVG).In this paper, the special materials that meet the requirements of metallic resonator Coriolis vibrating gyroscope are selected from a large number of alloy materials and studied and analyzed,and the effects of different heat treatment processes on the material properties and resonator performance parameters of metallic vibrating gyroscope are investigated.The experimental results show that the Maraging steel 3J33 has a good effect on the optimization of the performance parameters of the metallic resonator Coriolis vibratory gyroscope.
