Superfluid gyroscope is a new gyroscope based on cryogenic physics and technology with high precision, but it is still in the research stage of physical principle. Therefore, the research on superfluid gyroscope has great practical significance. The typical structure of double weak-link superfluid gyroscope is studied, and its improved model is explored.The basic principles and working mechanism of double weak link superfluid gyroscope are studied, the movement equation of solving constant input angular velocity is established and analyzed. The superfluid gyroscope's mathematical model is established based on the movement of double weak link superfluid gyroscope. The simulation shows that the double weak link superfluid gyroscope can detect the Earth's rotation angular velocity, and can effectively solve the constant angular velocity. The detection precision can be further improved by adjusting the sense area and diaphragm area of double weak link superfluid gyroscope.To solve the issue of angular velocity changes with time, improve the detection precision and expand the detection range of superfluid gyroscope, one improved gyroscope model is put forward in this paper. For the issue of angular velocity changes with time, the detection principle of double weak-link superfluid gyroscope is analyzed in theory, and solver equation about angular velocity changes are derived. Simulation shows that double weak-link superfluid gyroscope can effectively tracking angular velocity changes with time within a certain angular velocity. For the expansion of detection accuracy, the principle of interference grating superfluid gyroscope is analyzed, the movement equation is re-writed and the solution characteristic is analyzed. The mathematical model of interference grating superfluid gyroscope is established, and simulation shows that the detection precision of this gyroscope is improved an order of magnitude compared to double weak link superfluid gyroscope, which precision can achieve as high as 10 -4/ h.The superfluid gyroscope this paper researched has great potential of developping into ultra-precise gyroscope and has broad application prospects in the field of inertial technology..
