Adhesive joints are widely used in precision electromechanical products,and their bonding process has significant effects on the performance of an assembled product.This paper presents a numerical study on the bonding assembly of a sleeve structure of a precision inertial device using a finite dement method,where the stresses due to curing and relaxation behaviors are con-sidered.The effects of assembly errors and bonding defects on the centroid drift of the sleeve structure were found and analyzed quantitatively.This study can help understand the zero-drift mechanism of the precision inertial device and contribute valuable data for its error compensation.
