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 operating temperature quantitatively. It also verified the correctness of the model building comparing with the experimental results. On this condition, the effects of structural parameters, thermal parameters and temperature disturbed parameters on Shupe error in the fiber coil were analyzed. The results show that by optimizing the winding layers, increasing thermal conductivity, and arranging heat source rationally, the Shupe error of fiber coils can be inhibited, thereby enhancing the FOG thermal performance.
