摘要: 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 element method, where the stresses due to curing and relaxation behaviors are considered. 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.
