Study on Method of Intelligent Geometry Modeling of Gear Structure

Based on the knowledge of gear structure design,three sets,i.e.design parameter set,geometry constraint set of gear structure,and selecting condition set for gear structure-type,are abstracted.Then the knowledge system is formed and embedded in CAD system using certain knowledge representation methods.The parameterized gear structure design can be realized by programming,meanwhile the gear structure-type can also be selected by selecting condition set.
