Hot Air Forming Analysis of Automotive Rear Sub Frame using Aluminum Tube
알루미늄 튜브를 이용한 자동차 리어 서브 프레임의 열간가스 성형해석
Abstract
Recently, the hydroforming of high strength aluminum tubes has many studies and applications in manufacturing industry, especially in automotive industry. But high strength aluminum tube has limited expansion capability at most 15% at normal temperature. New manufacturing process, called hot air forming, is introduced to apply aluminum tube to the automotive sub frame components which have complex shape and require high expansion ratio about 40%. The process is carried out at the elevated temperature above
