The 3-D Structure Reconstruction of Engine Intake Manifold Based on RE Technology

Abstract

Engine intake system is one of the important parts of the engine which affects the engine’s volume efficiency and the uniformity of air entering to each cylinder directly Wherein the intake manifold with variable length is the important part of the intake system , has great significance value to research. Due to the structure of the manifold is complex, considering the manifold structure which affects the simulation accuracy, the principle of reverse engineering was used in this paper. Firstly, the laser scanning technology was used to obtain the point cloud data of the intake manifold.And then the cloud data was dealed by software Geomagic Studio12、NX Imageware13.The software UG8.0 was used to reconstructure the 3d intake manifold with variable length model.
