Abstract
As is known to all, new mechanical product design is always on the basis of the original product, so to better use the exiting design resource, a mechanical product variant design method is presented. The new method is based on SML and parameter CAD. According to different geological conditions of coal mine, different types of hydraulic support are needed to design. So as a typical kind of mechanical product, hydraulic support is given as an example to demonstrate the new variant design method. Finally with SOLIDWORKS as a specific application object, integrated with SQLServer2000 database, a hydraulic support variant design system is realized by Visual Basic program, which shortens the cycle of mechanical product development and reduces duplication mechanical design greatly.
