Air Intake of Engine Design based on Reverse Engineering and Rapid Prototyping Technique

In the design of air intake of engine,reverse engineering and rapid prototyping technique are used in this paper.Based on the prototype of the material object,we capture the point cloud data and construct its curved surface.Three dimensional surface data is input into UGII software for the analysis,optimization,and mould design.The three-dimensional model is laminated and the laminated files are transmitted to MAXUM FDM rapid prototyping machine for prototyping.By implementing this technique in the design of air intake,it is expected to dramatically reduce the designing period and cost,and provide valuable references for development,improvement,and innovation of the new products.
