白车身点焊焊点的三维定位数据库

摘要

To resolve the main problems of designing the new products,car structures are optimized on the premise that capability is met,and 3D positioning database of welding spots in BIW is established using simulation electrode's dimension and structure,which depend on existing clamp to ensure weldability of welding spots.This 3D positioning database provides reliable database to design and check up welding spots,which can shorten the time of the design and reduced the cost/These quicken the updating speed of car types and increase competitiveness of China's automobile products in world markets.%针对目前国内汽车产品开发过程存在的主要问题,在满足产品性能的前提下进行了产品结构优化,并依据现有的焊钳,通过采用电极结构尺寸仿真法制作了一个白车身点焊焊点的三维定位数据库,实现焊点可焊性识别,为点焊的焊点定位设计和审查提供可靠依据,这将大大缩短产品开发周期,降低成本,加快国内汽车车型更新速度,为汽车早日投入批量生产、抢占市场赢得时间,提高了中国汽车的竞争力.
