dc.description.abstract	本文主要針對板材非對稱壓延探討其壓延力及壓延扭矩，使材料於壓延製程安排上，更趨自由與多樣性，在壓延工業之應用上，具有極大之助益；但於非對稱壓延後之板材易產生彎曲現象而造成產品品質降低及設備損壞。 本文以試片厚度2.90mm的1050鋁板進行非對稱壓延實驗，以探討試片縮減率、輥輪周速比及界面潤滑條件對成形板材彎曲曲率的效應。實驗結果顯示，(1) 成形試片曲率達到平板狀態理想值(±0.0025)的縮減率發生在10%與40%；(2) 成形試片曲率達到平板狀態理想值(±0.0025)的縮減率和周速比係成正比的關係；(3) 不同界面潤滑條件對於壓延力及壓延扭矩有明顯的降低效應，且對改善成形試片曲率有明顯的效應。	zh_TW
dc.description.abstract	Due to the asymmetrical rolling can reduce rolling force and rolling torque that will make rolling process also flexible and variable. There are extreme advantages in application of rolling industry. The specimens will curvature after the asymmetrical rolling, the flat bending will reduce production quality and impact machine. This paper observe various of curvature ratio at specimens thickness 2.90mm asymmetrical rolling with different,mismatch peripheral speed,reduction, lubrication.The result is that:(1)The specimens reduction that curvature ratio is between ±0.0025 is incidence at 10% and 40%.(2) The specimens reduction that curvature ratio is between ±0.0025 is directly proportional to mismatch peripheral speed.(3) With Lubrication, rolling force and rolling torque is decreased.	en_US
