Parameterized Modeling for Visual Optimization Design of Mechanical Products

Visual optimization design (VOD) is a sort of modern design method based on three-dimensional model. The modeling speed affects the research efficiency of VOD directly, and it was found that the parameterized modeling can develop the model rapidly due to parameter drive which will serve VOD well. The method of parameterized modeling is proposed for VOD of mechanical products. Analyzing the relation between parameterized modeling and VOD, the general procedure to implement parameterized modeling is proposed including such crucial steps as determining functional modules, analyzing parameters, parameterizing the modeling process of different parts and assembling auto control system. With a 3-PPT parallel kinematics machine tool taken for testing, on which a parameterized modeling system is developed using the software VB on the SolidWorks as platform, thus verifying the validity of the method proposed.
