Since May 2003, On-line test to validate the interface between electrified conventional track, rolling stock, power supply and signalling system. Main test items are the suitability of the system such as vibration of the rolling stock, noise, current collection, track and signal system. In this article, part of the vibration and noise related test results are introduced such as the vibration of the carbody and bogie, running stability, jerk, interior noise of the passenger car and driver"s cabin.

유럽은 2008년 철도시스템 상호운영지침을 개정하고, 2014년 고속철도와 일반철도를 통합한 기관차 및 객차에 대한 TSI를 제정하였다. 국내의 경우 2012년 12월 철도안전법이 전면 개정되며 철도차량과 용품의 형식승인제도가 운영 중에 있으며, 철도차량의 형식승인제도는 형식승인, 제작자승인, 완성검사의 3 단계로 이루어진다. 유럽의 TSI 인증 체계를 소개하며, 국내 형식승인제도와 비교한다. The European Community Revised the Interoperability directive in 2008 and legislate the Technical specification for interoperability to locomotives and passenger rolling stock’ subsystem in 2014. The MLIT of Korean government wholly amended the Railroad safety act in 2012, and enforced the type approval system for the rolling stock. The type approval scheme is composed of type approval scheme for rolling stock, manufacturer approval for rolling stock and completion inspection of rolling stock. The TSI certification system is introduced and compared with type approval system.

In this study, quarter vehicle model is used to analyse vibration control effects for ride comfort and handling safety according to this three kinds of control methods, which are the modal control, the sky-hook control and the linear viscous damping control. We performed theoretical analysis and experiments and compared two results. In experiments, electro-magnetic actuator was employed as a force actuator. It is shown that all three methods can effectively control the vehicle model. The modal control method gives similar control results using gain less than the viscous damping control.
