For a good crashworthy design of train vehicles, it is essential to develop some design and analysis techniques for energy absorbing structures. This paper analyzes the front structure of TGV-K and suggests crashworthy design of Korea high speed train(KHST) using the accident scenario of SNCF(collision with a stationary rigid mass in motion of 15 ton at 110 ㎞/h). Specifically this reserch is concentrated on developing a well-designed protective headstocks using mullticell structures with cutouts to improve crashworthiness of KHST.

Because a driver is located in the front end of KHST, he is most likely to be insured at collision accidents. So, it is very important to design some survival space for the driver. To evaluate the driver"s safety of KHST (Korean High Speed Train), the front structure of power car is analysed using PAMCRASH under the SNCF accident scenario(collision against a movable rigid mass 15 ton at 110 ㎞/h). Because the driver"s cab of KHST is a modified version of TGV-K, which is not so strong as to protect him, it turns out to be inadequate to guarantee his survival space. Therefore it is recommended to redesign the driver"s cab in a crash worthy point of view like the case of TGV-Duplex or NEC.
