The nonreciprocal thermal rotation rate error (shupe error) produced by the fiber coil in the changing temperature field is simulated and analyzed, and a new method for winding of the fiber coil is proposed to reduce the shupe error.Firstly, the finite element models of the fiber coil with skeletons are established respectively with three kinds of symmetrical winding methods, and the same uniform temperature field load varying with time is applied to the three models.After analysis and calculation, the temperature change rate of each turn in the fiber coil is obtained.Then, the shupe error of the fiber coil under the three winding methods is calculated respectively by using the mathematical model of the thermal rotation rate error of the fiber coil, which is accurate on the turn level.The simulation results show that the shupe error is best suppressed by using the new reverse-crossing symmetrical winding method.
