Currently in design and manufacturing of railway train overseas markets, criteria for a collision condition between vehicles is noted in design specification. In the event of a train crash, it can be verified by crashworthiness analysis or an actual crash test for car's performance to keep the safety of passengers and to minimize the effect of damaged for vehicles. In this paper, it is described for carbody structure to meet the allowable condition in collision analysis through improvement of shape, position and arrangement for carbody frame. This report describes the shape of end frame for carbody structure and the results of analysis applied to actual cases for overseas.

인천공항 자기부상열차에 적용된 출입문은 플러그인 슬라이딩 타입으로서, 차체측 방수프레임 및 출입문 패널상의 방수고무의 접촉에 의해 방수 기능이 구현된다. 본 열차의 방수 성능은 완성차 시험 단계에서 평가되며, 자기부상열차의 구조적 특성으로 인해 차량 기지내에 설치된 세척 장비를 활용하여 누수 시험을 진행하였다. 초기 시험시 출입문 부위에 다수의 누수가 발생하였으며, 이를 해소하기 위해 방수 고무의 단면 형상을 변경하고, 침투한 수분의 용이한 배수를 위한 추가 구조를 적용하였다. 또한 시험에 적용한 세척 장비의 수압 및 유량을 감안하여 KS 규격에 명시된 철도차량 누수시험 기준을 만족할 수 있는 시험 방안을 도출한 후 실제 시험에 적용하여 방수 성능을 검증하였다. The Passenger entrance doors for the MAGLEV of Incheon International Airport are plug-in sliding type, and the waterproof performance is achieved by contact of sealing rubbers and sealing frames fixed on the carbody. The waterproof performance of this vehicle is tested in the stage of complete vehicle test, and this test was done with the vehicle washing system in the vehicle depot. During the initial test, water leakage was found on these doors, and the modification of the sealing rubbers and re-definition of test standard was done for prevention of the water leakage. After this modification, the desired waterproof performance was achieved, and this performance was checked in the final waterproof test.

In recent carbody design of rolling stocks the development of a new carbody structure rather than designing the carbody structure by applying a proven new way to design the carbody structure has been applied. Structural requirements of the carbody being equal the same applies to the carbody structure means that it is possible to design a carbody structure. By kinematic envelope & speed and the environment etc. the carbody design is in progress. Accordingly if all conditions are the same as the existing carbody structure by the same criteria is that you can go get the same. Rather than developing a new carbody structure carbody structure by applying proven that safety is secured is made possible. Proven standard model of the carbody structure of rolling stocks to secure a new carbody design has made it possible to apply. In addition the size of the different carbody but structural requirements are the same body design is easier to be expected. In this paper a model standard carbody of rolling stocks is chosen and of a new carbody design that can be applied to the carbody design will attempt to demonstrate the case.

Current freight electric locomotives (132 ton) of the eco-friendly and can carry large cargo logistics as a means of generation has increased the demand at home and abroad. Especially Freight electric locomotives to increase the traction it is easy to mass and rapid transport. In addition Freight electric locomotives is no exhaust and low noise compared to diesel –electric locomotives and it can be eco-friendly transportation. CO_CO BOGIE of Freight electric locomotives has no the center pivot and Traction_Rod and Spring of CO_CO BOGIE is mounted on the body. These freight electric locomotives to be satisfied with the safety regulations. Carbody development satisfied Implementation of optimum body and collision is the focus. Accordingly the different approach in the upper and lower carbody structure and interior and equipment placement is needed. On this paper the contents give explanation of cases on carbody design composed of freight electric locomotives now developed and process of improvement by structure analysis and collision analysis.
