This paper introduced the relevant knowledge of miniature car valve train of engine based on Pro/E and the analysing of miniature car valve train of engine based on ANSYS.It summaried of the current miniature car valve train of engine manufacturing technology and development trend.Through the understanding of the using performance, working conditions, structure, the technical requirements, the author drew graphic model of the valve train with Pro/E and assembled of the valve train of engine.In the process of finite element analysis,it applied ANSYS that popular software of finite element analysis.Through the Pro/E three-dimensional modeling,it inport this model into the ANSYS software to analyze.In recent years, with the popularization of computer technology and the continuous improvement of computing speed ,finite element analysis in engineering design and analysis has been more and more attentioned,it has became an effective way that solving complex computing problem of engineering analysis,it has an importan actual application value in the project.Based on the above description,we can know that the design can improve manufacturing efficiency,save labor and productive resources in theory,it can speed up the production process of automobile enterprises and the process of manufacture,the Pro/E can combinate with the ANSYS to shorting the traditional development cycle than AutoCAD design and increases the production level.
Key words:valve train;Pro/E;Three-Dimensional Map;ANSYS;Finite Element Analysis
