Modeling of complicated object three-dimension virtual construction based on reverse engineering

Geometry model, as a mapping on physical space to calculating space, is a foundation of numerical simulating. Aiming at a complicated object, reverse engineering technology was applied to model cylinder head. Using Pro/Engineering modeling software, inlet port, outlet port, up water jacket and bottom water jacket geometry bodies were modeled one by one. Finally, by Boolean calculation, a cylinder head model was built up, which had higher precision and afforded a good model for further simulating calculation on cylinder head.
