Abstract: Gap evenness and flushness between BIW (Body-in- white)
openings and closure panels not only affect auto-body product anesthetic
value, but also cause functional problems. Aimed to improve fitting
quality, the Hausdorff distance is used to measure the degree of match
effect and a synthetic fitting model is proposed combining influence of
welding thermal effects. A genetic algorithm is utilized to search
global optimization of interest fitting variables and a software
prototype is developed.
Key words: Closure panels Best fitting Welding thermal effects
