Abstract

This paper describes the buckling pattern of the body frame by energy absorbed efficiency of crashworthiness related to research of the buckling characteristics of aluminum cylindrical pipes with various diameters formed mechanical tools. Experiments were performed by the quasi-static test without lubrication between specimen and equipment. According to the change in the radius versus thickness of the specimen, the buckling phenomena are transformed from folding to bellows and the rate of energy absorption is understood. In crashworthiness, frames are characterized by the folding among three patterns from the absorbed energy efficiency point of view and weight reduction. With the development of new types of transport such as electric vehicles, innovated body structure should be designed.
