Abstract: Aiming at solving the problem of complicated upgrading in the process of threedimensional modeling of complex parts, the method of parametric modeling of cylindroid helicalcoil compression springs in SolidWorks has been explored. The threedimensional model of cylindroid helicalcoil compression springs was firstly established and the characteristic dimensions controlling the spring structures was set as the variant parameters, the VB applications were developed by Visual Basic 6.0, combined with the technology of Access 2003 database. A series of cylindroid helicalcoil compression springs can be generated automatically by assigning different values to the variant parameters through the manmachine dialogue window in the VB interface. The results indicate that the automaticity of threedimensional modeling of complex parts can be improved significantly by means of parametric modeling.
