| 摘 要： | 基于交流约瑟夫森效应的超流体陀螺研究是当前高性能新原理陀螺技术研究的一个重要方向。低温物理中基于交流约瑟夫森效应敏感转动角速度的典型双弱连接超流体陀螺方案原理上具有高灵敏度的技术优势,从工作原理上来说目前该方案要发展成有实用性陀螺仪面临着量程小这一关键问题,仿真分析表明了量程的范围与敏感面积和约瑟夫森频率的影响关系,并显示了仅调整这两个参数扩展量程范围的局限性,进而在此基础上研究了扩展量程的改进思路和方法。

| Abstract: | The research of superfluid gyroscope based on AC Josephson effect is important for the development of high-performance gyroscope.In this paper,the typical superfluid gyroscope with double weak-links is described to show how it detects angular velocity by cryogenic superfluid AC Josephson effect and obtains high sensitivity.The key problem,that the measure range of current system is too small to develop practical gyroscope,is also analyzed.The system model and simulation results of this problem are given.The... |
