A Rapid Adjustment Simulation System for Flexible Fuselage Assembly

Abstract:

The utilization of reconfigurable numerically controlled tooling is important for flexible fuselage assembly. An online programming and simulation system for flexible tooling is presented, which is composed of two modules. The online programming module generates NC code from an adjustment sequence and path, taking into consideration the process and device parameters. This paper details the second module, the visualized simulation module, which validates and optimizes the related adjustment process. This module covers three steps, those are, the creation of a virtual simulation environment based on the light-weight 3D model, the loading of the key feature points related to the adjustment and process information, and the adjustment simulation. The system can rapidly response to “one fixture with more models” and “one fixture with more states” deep flexibility demands for digital fuselage assembly, enable the flexible tooling to a have better capacity for independent adaptability. An example of flexible fuselage assembly process is used to illustrate the detail and advantages of the system. The three-step simulation strategy is proposed and detailed in this paper.
