The Research And Application Of Motorcycle Gasoline Tank Modeling Technique Basic On Reverse Engineering

With progress of industrial technology and development of economy, people have increasing high demand for products. So products not only should have advanced function, but also smoothing and personalized product appearance. And the latter has become the important factor affecting the product competitiveness. Motorcycle gasoline tank which is the major component part of motorcycle coverage is the typical representation of this type. Not only does it have assembly accuracy with other pieces, but also more importantly smooth appearance. Moreover, reverse engineering technique can make direct conversion from object to geometric model. So it can provide an efficient and new reconstruction method for manufacturing. Therefore, the use of reverse engineering technology for CAD modeling of motorcycle gasoline tank has become the trend of modern manufacturing technology development. So, the paper makes research on modeling technique of motorcycle gasoline tank based on reverse engineering.First analyze the advantages and disadvantages of contact measurement and non-contact measurement. Based on the analysis of motorcycle gasoline tank surface characters, the method and flow of data measurement motorcycle gasoline tank based on reverse engineering are mentioned. Then make research on the data process technique of motorcycle gasoline tank based on reverse engineering. Aimed at the characters of motorcycle gasoline tank cloud, select the data process method of motorcycle gasoline tank oriented from general data process methods. Also study on the technique of each method. A motorcycle gasoline tank is given as an example to do the data measurement and data process.According to the quality of cloud and shape of motorcycle gasoline tank, select the surface reconstruction methods constructed from curves or cloud directly. Advance the method and flow of model reconstruction of motorcycle gasoline tank based on reverse engineering. Finish the surface model reconstruction by two steps which are construction of basic surfaces and construction of transitional surface.Analyze the methods and disadvantages of existent model measurement. Advance the model measurement of motorcycle gasoline tank based on reverse engineering, and analyze its characters. Make measurement for CAD data of motorcycle gasoline tank. Analyze the measuring results to amend the measuring errors. Finally the modeling techniques researched in the paper are applied in a gasoline tank factory. The CAD modeling data of a motorcycle gasoline tank is constructed. And the CAD data can satisfy the demands of the enterprise. It can save the manufacturing cost of gasoline tank mould and enhance its manufacturing efficiency...
