| 摘 要： | 在光纤陀螺Shupe误差数学离散公式的基础上,建立四极对称法绕制光纤环的有限元模型,分析多材料组成下的光纤环在仿真时所需的综合物性参数.结合光纤陀螺工作环境的载荷和边界条件,对某型光纤环进行数值仿真,定量分析了光纤陀螺在工作温度下光纤环的Shupe误差,验证了模型建立的正确性.在此条件下,分析光纤环的结构参数、热学参数和热扰动参数对Shupe误差的影响.结果表明:通过增加绕制层数,提高导热系数,合理布置热源,可以明显抑制光纤环的Shupe误差,从而提高光纤陀螺的温度性能.

| Abstract: | The element model of the fiber coil with the quadrupole(QAD) winding pattern was built based on the discrete mathematics formulae of the Shupe error in the fiber optic gyroscope(FOG),and the comprehensive physical parameters of the fiber coil with multi-material composition were analyzed for the next simulation.Combining of the thermal loads and boundary conditions in the FOG working environment,the numerical simulation of the fiber coil was done to analyze the Shupe error in the fiber coil at the FOG opera... |
