Aiming at the demands for high precision forming of continuously multi-bent tube in space, this paper reviews the developments of simulation technologies at domestic and abroad. This work proposes simulation process knowledge for tube based on knowledge-engineering. A geometric motion simulation system about tube is established by parametric driving. The extraction of model data, selection of process parameters, creating simulation models, bending process simulation, simulation of springback process, generation of simulation reports and NC code can be automatically realized by applying this system in the continuously multi-bent tube of aircraft. This simulation system can reduce working intensity of technicians and improve work efficiency at process planning in tube of aircraft.
