The Research And Development On Several Modules Of Parametric Design System Of Elevator Car

With the rapid development of our country’s real estate, our country is not only the largest market, but also the most production capacity of elevator in the world. Facing onto the wide and diverse needs, every elevator company would have to reduce the production time and guarantee the quality of products. But the traditional design procedure of mechanical products is drawing design, sample test, modifying drawing, and mass production, it is not suited to the development of the mechanical manufacturing industry, and the improvement of design procedure is urgently demanded. In this context, many internal enterprises have purchase some CAD/CAM softwares well known in the world like Pro/Engineer, UG, CATIA and so on. But these softwares are normally commercial and unprofessional platforms, and these platforms can’t adapt each kind of demand of concrete design. Therefore, the secondary developments of CAD softwares are the questions we have to face and solve in the process of applying the CAD technology.The paper introduces how to research and develop several modules of the parametric design system of elevator car combining with enterprise’s technology by using Pro/TOOLKIT in Pro/Engineer and VC++. First, the paper establishes the whole plan of parametric design system; second, it redevelops Pro/Engineer by Visual C++and SQL Server; third,3-D template, unfolded graph of sheet metal and drawing template is introduced, and parametric design is introduced combining with side car walls and parametric script; last, the article introduces how to execute several modules of the parametric design system of elevator car. The developing of platform selects Visual C++which is object oriented and visual developing language as main language. VC++and SQL Server are linked by ADO technology. The platform’s function includes creation of model tree, saving basal information about model, making the model modified by the experience script, generating model and drawing of new products and so on.
