Model Simplification Method of Visual Attention and Lightweight Assembly Technology

Abstract

Abstract: A model simplification method of visual attention and lightweight assembly technology was presented. The part model library with 6-level of details from the most detailed to the null model was established. The method of calculating the dynamic level of details of standard part models was presented based on assembling parts related visions，structures and kinematic chains, also the function of switching different detailed models was implemented in assembly design according to this level definition of details. The method was used in amphibious aircraft design and the design efficiency is obviously improved.

Key words: standard part, model simplification, visual attention, multi-level of detail, lightweight assembly
