Abstract. A computer model has been developed to predict temperature drift of sensing elements in fiber-optic gyroscope under external thermal and mechanical actions with the account for the piezo-optic effects. A distinguishing feature of the model is that computation of the stress-strain state of the structure is based on detailed discretization of each turn of the optic fiber in the optic fiber loop. The model is implemented in the framework of the STAR-CCM + software used in combination with a post processor developed by the authors.
Keywords: fiber-optic gyroscope, drift, fictitious angular velocity, computer model, thermal elasticity, piezo-optics
