A Study on Structural Strength in Carbody Structure of an Express Train

초록

we attempted to make a lightweight vehicle structure in order to reduce the amount of parts and materials used in its manufacture, and reducing the vehicle’s energy consumption by making it as lightweight as possible. The manufacture of a vehicle made of aluminum requires a high initial investment and huge spending. However, it is expected that the production of such a lightweight vehicle will produce considerable improvements in terms of increasing the speed and reducing railroad maintenance charge. Recently, as aluminum alloy extrusions are becoming larger and with the further advances in technologies for making them into thin sheets, the assembly method using an extruded shape is being adopted.
