摘要: 为研究新型高精度超流体陀螺的动态性能,分析了影响其可测的角加速度因素;在构建了热驱动时约瑟夫森频率数学模型的基础上,对可测的角加速度进行了数值分析。研究结果表明:根据通用的参数,超流体陀螺可测的角加速度最大值约为0.32 rad/s2,因此超流体陀螺的动态性能较小,它适合应用于对角速度的精度要求很高,且角速度缓慢变化的领域。

Abstract: In order to research the dynamic performance of a novel superfluid gyroscope, the factors which have effect on the detectable angular acceleration of gyroscope are analyzed. Based on the mathematic model of Josephson frequency for thermal driving, the detectable angular acceleration of gyroscope is simulated. The results show that, according to common parameters, the maximal value of detectable angular acceleration is about 0.32 rad/s2, so the dynamic performance of superfluid gyroscope is small. The gyroscope can be used for the field which requires the higher detection accuracy and slow change of angular velocity.

Key words: control science and technology, superfluid gyroscope, matter wave, Josephson frequency, dynamic performance, angular acceleration
