The Parametric Design Of The Vehicle Chassis

Parametric design, as an entirely new method of design, has been introduced abroad by industry. Its advantages make it the direction of future design. As the nucleus of manufacturing, automobile industry requires the parametric technology more urgently. The application of parametric technology decides the efficiency and the quality of design in one corporation. Because the efficiency and the quality of design mean the core competition of one corporation, it is an important problem about the development of one corporation.This thesis introduces the evolution and actuality of CAD and the parametric technology, dissertates the basic thought of parametric design and the theory and its program of the realization, and applies the language of Visal LISP and DCL obeyed by the working flow of software project, which open up the system: Chassis Parametric Designerl. 0.This system can realize the parametric assembly of the automobile chassis and adjust the wheelbase by dragging the mouse or driving the dimension. The system can also display the change about the wheelbase. It makes a firm base for upgrade of the system. Some ideas of the system may supply many references for other developers. At the same time, with the further upgrade and development, the system will turn to the high-level commercial system.
