Study on Visualization Design Method of External Pipeline Assembly for Aeroengine Based on UG and 3DVIA

The design of assembly process of external pipeline for aeroengine is difficult, assembly process cycle is long and with poor visibility. In order to solve these problems, a kind of visualization method to design assembly process for external pipeline based on UG and 3DVIA was put forward. The author described the overall process and implementation of the visualization design method, which included modeling process model, the visualization design of assembly process and output of visualization design. Besides, by the use of the visualization method, corresponding solutions for some certain issues, such as the unconventional disassembly of the external piping, the change of assembly process because of redesign of external pipeline, and the way to reduce the assembly stress. The application results show that the visualization design method could improve the quality and efficiency of external aeroengine pipeline assembly, the assembly animation and 3D drawing is a guide to the field assembly working.
