Part Parametric Modeling Technology Research Based on Function Module

Firstly this thesis summarized the research status about traditional modeling technology and the feature-based parameterized modeling technology about components. Secondly the article developed an idea of part parametric modeling technology research based on function module and its program realization method, on the basis of analyzing mechanical characteristic decomposition and building, parameter constraint condition, methods of module creating division and combination and numerical simulation of the part components modeling. In the text of the dissertation we also gave an example of gears and verified the validity and practical applicability about the text of the proposed method. Application of modular modeling technology can shorten modeling time and improve parts design efficiency for the same type and series of part. Especially it has great reference value on the creation of complex model.
