A Study on the Structural Design of Carbody by Stress Measurement

초록

For the carbody material of urban railway vehicles, the tendency is toward lightweight material such as from steel to stainless steel, and from stainless steel to aluminum alloy. Aluminum alloy is recently on the spotlight as the material of next-generation railway vehicles because it is light and has proper strength. Such a transition requires an efficient designing to ensure that it satisfies the increasing the need for scaling up as well as being lightweight. Accordingly, modeling was performed and structural stress analysis was carried out for the body structure of the urban railway vehicle manufactured with aluminum alloy.
