Development of Automotive Chassis Parts Using the Hydroforming Technology

하이드로포밍 기술을 이용한 자동차 샤시 부품 개발

In the present study, front lower arm and engine cradle which are automotive chassis parts were developed using the hydroforming technology. For systematic establishment of parts development process, material properties of tube were reflected at the start of design and problems of initial design drawing were solved by forming analysis. Design and manufacturing technology of hydroforming die were established and the relationship between internal pressure and feeding stroke was studied during try-out. Durability and buckling strength of hydrofromed parts were estimated.
