摘要：The assembly gaps has been an essential part in the quality assessment process in the field of building the aircrafts. To figure out the changes of the whole structures caused by the assembly gaps, some specific experiments are carried out by recording the shape deviations of the relevant components. And the specific shim with the epoxy and glass fibre mixed is utilized for compensating the gaps, where the solid shim can also be applied. The comparison of compensating effects of the different shims has been illustrated as follows, in which the deformations was prevented effectively with the aid of either of shims. However, deformations in the roots of the gaps can be better limited by the mixed shim, where the max strain can be decreased by around 20%.
