Parameterized computer aided design of stubble cleaner

Abstract

The traditional agricultural machine design were represented as 2D drawing, which is difficult to modify, and also not intuitive in the solid way for the form and structure. Therefore, software, was used to conduct parameterized design of stubble cleaner parts. The parts were designed associatively and assembled virtually. The structure of the whole machine and the spatial distribution of parts can be seen and analyzed intuitively. Under UG-NX3 circumstance, the designed 3D model can be transformed automatically to 2D drafting which is used in fabrication and production. The result proved that computer aided parameterized design can allow dynamical operation, preview and repeated modification of the design, reliably and quickly. Therefore, the optimum design efficiency of stubble cleaner is improved; 3D modeling time and 2D drafting time is greatly decreased. © 2008 International Federation for Information Processing.
