The Research of Modular and Parametric Design Technology of Overhead Traveling Crane's Bridge Structure

As to improve the poor design method of overhead traveling crane,this paper analyzes configuration characteristic of overhead traveling crane's bridge structure,partitions bridge structure into modules with modularization idea,proposes a efficient parametric modeling way,adopts parametric program design and introduces database design to manage primary parameter data,discusses the automatic drawing adjustment design based on the parametric environment,then achieves automatic design from 3D model to 2D drawing.It proves this technology greatly improves design efficiency and quality after application in Taiyuan Heavy Machinery Group Corporation.
