Visual optimization design (VOD) is a sort of modern design method based three-dimensional model and modeling speed impacts the research efficiency of VOD directly. The technology of parametric modeling can build model rapidly by parameter drive, so it can provide good serving for VOD. In the paper, the method of parametric modeling is studied based on VOD of mechanical product. The relation of parametric...
Bases on the virtual prototyping technology, a CAX integrated analysis environment in the PC platform is built. By the CAX, a simulation model of crankshaft system of internal combustion engine is built. The model is then used to analyze the kinematics and dynamics characteristics of some type crankshaft system. Through comparing the data of simulation result with that of classic literature, the virtual...
