Research of Parametric Design for Components Based on Solid Works

The thesis discusses the parametric modeling method of components completed by adopting the parametric method based on assembly constraint through their parametric links of product,components and parts under the SolidWorks.Meanwhile,it introduces the key technique of this method,including the partition of products' structure,dimension analysis,relating design,assembly design based on layout sketch and the accession of equation.The thesis creates a components library in the SolidWorks by using the method of parametric design for components.Adopting this method will be in favor of the modification and serial design of a product,and raise the design efficiency.
