Technical Paper


In order to resolve and improve the reverse design of the inner chamber parts, the airflow model of an engine’s cylinder head was taken as research object, and the reverse design methods used for complex inner chamber parts were explored based on slicing method. According to the structural and functional features of airflow model of the cylinder head, the technologies of measure and treatment for the point cloud data were studied, and the technologies of fitting the contour curve based on different sections and features, reconstructing surface based on different segments and features for the airflow were proposed. It can be seen from the error analyses and engineering practical experiences that the quality and accuracy of the reconstructed model can be ensured and improved with this reverse design method. It has reference significance for the design and reverse design of similar inner chamber parts.
