Assembly variation analysis of flexible curved surfaces based on Bézier curves None

Zhen-yu LIU, Shi-en ZHOU, Jin CHENG, Chan QIU, Jian-rong TAN

Frontiers of Information Technology & Electronic Engineering 2018, Volume 19, Issue 6,   Pages 796-808 doi: 10.1631/FITEE.1601619

Abstract: Assembly variation analysis of parts that have flexible curved surfaces is much more difficult than thatof solid bodies, because of structural deformations in the assembly process.Most of the current variation analysis methods either neglect the relationships among feature pointsIt solves the variation analysis problem of flexible curved surface assembly when considering surfaceFinally, the proposed method is illustrated in two cases of antenna surface assembly.
