Abstract

The vibration characteristics of railway vehicles are very complex because they are not only dependent on vehicle and track conditions but also on operating conditions. Vibration can cause the failure of rolling stock equipment. To verify that the quality of rolling stock equipment is acceptable, it should be able to withstand vibration tests of reasonable magnitude and duration. There are many standards for vibration and shock tests of equipment in Korea. In this paper, we have reviewed and compared the standards (KS R 9144, R 9146 and IEC 61373) for vibration and shock tests.

철도차량은 차량조건, 선로조건 및 운행조건들에 의한 많은 진동원에 의해 매우 복잡한 형태의 진동과 충격이 발생한다. 진동과 충격은 철도차량에 부착되어 있는 부품 및 구성품을 고장시키는 원인이 된다. 이러한 진동 및 충격에 의한 장치의 고장을 줄이기 위해서는 개발단계에서부터 진동과 충격시험을 통해 장치가 진동과 충격에 견디는 지를 확인한 후에 철도차량에 장착하고 있다. 국내에는 서로 상이한 방법을 적용한 여러 가지의 철도차량 진동 및 충격시험 규격이 사용되고 있다. 본 논문에서는 국내에서 대표적으로 사용되는 규격인 IEC 61373과 KS R 9144, KS R 9146에 대해 상대적 비교를 통해 진동과 충격시험의 방법에 대한 차이점을 고찰함으로써 진동시험 관련자들이 정확한 진동 및 충격시험을 할 수 있도록 하고자 한다.
