Abstract: | Within the framework of this article, the concept of parts computer-aided parameterized design is presented. A methodology is developed of analytical description of the complex surfaces of the parts in the machines building industry. An original mathematical model is afterwards identified for the analytical description of the active surface of one of the most complex shape in mis field, the one of the plow moldboard. An AutoLISP program was developed for the design and display of any type of moldboard, using AutoCAD Release 12, the most wide-spread CAD program presently existing in Romania. The moldboard model thus generated can be easily converted and exported for the finite-element analysis in NASTRAN, ANSYS etc. with a special view on optimization. |
