In this thesis it was proposed to simulate the drawing , trimming , flanging by using error - adjustment method . the initial trimming lines would be adjusted and optimized in the computer by adjusting error . if the shape error between the flanging boundary line and the target is larger than prescribed , the redundant area is subtracted from the initial blank by some amount of volume along the deformation path , and the insufficient volumes are added to the initial blank by the same amount 本文提出,利用基于變形路徑的誤差修正法( error - adjustment ) ,結(jié)合cae技術(shù)將對(duì)初始修邊線的調(diào)試過(guò)程在計(jì)算機(jī)中進(jìn)行模擬(包括拉延、修邊、翻邊、整形等)計(jì)算,通過(guò)控制翻邊后零件成型邊界與實(shí)際目標(biāo)輪廓之間的尺寸誤差來(lái)優(yōu)化修邊線,如果初始切邊、翻邊后的輪廓與目標(biāo)體的邊界存在較大偏差,則初始切邊輪廓中多余部分單元將沿其變形路徑以相同體積量被切除,不足部分則沿其變形路徑以相同體積進(jìn)行補(bǔ)償。
