N2 - In the adhesive assembly of precision inertial instruments, it is easy for the center of mass to shift due to creep in the adhesive structure, resulting in a reduction in the accuracy of the instrument. In the presence of ambient temperature variations, these center of mass shifts can change further, causing variations in the accuracy of the instrument, that is, the accuracy stability problem. This paper investigates this accuracy stability problem. Firstly, numerical simulation modeling of an adhesive structure with assembly errors is carried out, then the center of mass displacement of the structure due to creep of the adhesive structure under different temperature loads is analyzed, and finally, experimental verification of the simulation results is carried out by developing a structural creep experimental device to verify the validity of the simulation results. This thesis provides a theoretical reference for the stability control of the accuracy of adhesive structures with assembly errors.
