Abstract:

In order to solve the problem of automated drilling on the circumferential region in splice section of the fuselage, a lightweight, flexible, portable, multiple spindle, automated NC machine is introduced, the circumferential track drilling system. The equipment's primary structure and functions are described in this paper. First, the finite element model of the circumferential flex track drilling system is established by ABAQUS software. Then the pretightening force of the support foot that guarantees the location and installation is calculated by simulation. The key load bearing of the equipment and the deformation of the circumferential track with static load are analyzed by simulation. According to the result of the finite element analysis, a position installation scheme is put forward to improve structure' force situation, decrease deformation of the circumferential track and increase drilling accuracy. Then a dynamic analysis is performed to demonstrate the equipment's dynamic characteristics. After a test of drilling with the prototype of the equipment, its drilling effects are verified.

Key words: mechanisms, automated drilling, finite element method, circumferential track, locating scheme, modal analysis
