提出了一种新型组合式熔融石英圆柱壳振动陀螺仪。熔融石英谐振器的筒壁和底盘是分开制造的，然后用胶水连接起来。采用这种方法，可以显著降低熔融石英圆柱体振动陀螺仪的制造难度。首先分析了组合熔融石英谐振器的结构特点和振动模式，然后介绍了陀螺仪的制造工艺，包括组合谐振器的加工工艺、减小固有频率分裂的质量平衡方法以及陀螺仪的控制电路。最后，对组合陀螺仪进行了性能测试，包括Q因子测试、频率稳定性测试和偏置稳定性测试。实验结果表明，组合式石英圆柱体振动陀螺仪在室温下具有良好的偏置稳定性，具有实现更高精度的潜力。
We propose a novel combined fused silica cylinder shell vibrating gyroscope. The cylinder wall and the bottom disk of the fused silica resonator are fabricated separately and then are connected by glue. By using this method, the difficulty of manufacturing the fused silica cylinder vibrating gyroscope can be significantly reduced. The structure characteristics and vibration modes of the combined fused silica resonator are first analyzed and then the fabrication processes of the gyroscope are introduced, including the machining process of the combined resonator, the mass balancing method for minimizing the natural frequency split, and the control circuit of the gyroscope. Finally, a performance test of the combined gyroscope was implemented, including a Q factor test, frequency stability test, and bias stability test. Experimental results show that the combined fused silica cylinder vibrating gyroscope has good bias stability at room temperature and has the potential to achieve higher accuracy.
