Method for suppressing temperature error or vibration error of fiber optic gyroscope

The invention relates to a method for suppressing a temperature error or a vibration error of a fiber optic gyroscope. Geometric modeling of a fiber ring and simulation calculation of temperature andstrain distribution are performed in finite element analysis software by using the winding and material parameters of different actual fiber rings, different values are taken from the elastic modulusof the ring surrounding rubber of the fiber ring within a range of 1 MPa to 1 GPa for analog simulation to obtain a temperature error or vibration error curve of the fiber optic gyroscope when usingring surrounding rubber of different elastic modulus, thereby finding the corresponding elastic modulus when a thermal drift error or a vibration output error is minimum. Since the fiber ring is madeof the ring surrounding rubber, the environmental adaptability of the fiber optic gyroscope is improved under the same condition. 本发明涉及一种抑制光纤陀螺温度误差或振动误差的方法，利用不同实际光纤环的绕制和材料参数，在有限元分析软件中进行光纤环的几何建模和温度、应变分布的仿真计算，将光纤环绕环胶的弹性模量在1MPa到1GPa
