摘要/Abstract

摘要： 超流体陀螺是新一代惯性传感器，其面临的关键问题是：输出存在较大的噪声，引起其高测量精度的潜力不能发挥。为此，基于对管路多圈环绕时的流体感抗分析，构建了多圈环绕时超流体陀螺噪声的数学模型；并综合考虑多圈环绕对超流体陀螺的影响，研究最优环绕圈数，提出基于多圈环绕结构的噪声抑制方法。研究结果表明，随着环绕圈数的增加，超流体陀螺的噪声呈现逐渐下降的趋势。根据通用参数，采用最优圈数进行多圈环绕时，超流体陀螺的噪声值被抑制为无多圈环绕时的1/4. 因此基于该方法，超流体陀螺的测量精度得到了显著提高。

Abstract: Superfluid gyroscope is an interferometric gyroscope based on matter wave. One of the key problems that it faces is that its output noise is very high, so its high accuracy measuring capability cannot be exerted. A mathematic model of the gyroscope noise is established based on the analysis of hydrodynamic inductance for pipeline being circled with multiple-turns. Considering the influence of multiple-turns on superfluid gyroscope, the optimal quantity of turns is researched. A method for noise suppression based on multiple-turns circling is presented. Simulated results show that the noise of superfluid gyroscope is decreased gradually with the increase in multiple-turns. Based on common parameters, the noise of superfluid gyroscope with optimal multiple-turn circling is 1/4 of that without turn. The research results show that the measuring accuracy of superfluid gyroscope is increased remarkably by using the proposed method. Key
