To implement interference detection and simulation of the moving trajectory of aircraft components and toolings in the assembly process, a method of motion data integration and monitoring of digital assembly system of aircraft is proposed. Every digital model of the equipments was separated into several components according to its degrees of freedom. And manufacturing errors and assembly errors of the moving components were considered when building the digitized geometry scene of the assembly system so that it is consistent with the actual situation. Then the scene was displayed using real-time data of the equipment positions and velocities. By using an improved CinDeR algorithm, interference between the safety buffers of the geometrical models was detected and avoided. A practical engineering application is provided to verify the correctness and effectiveness of the proposed method.
