Abstract

This study describes impact test methods for a rolling-stock windscreen executed in Korea and Europe. Air-pressurized impact test equipment for the front windscreens of high speed trains was designed and manufactured. The equipment is capable of launching a projectile at 500km/h, in accordance with EN 15152's impact test method. Calibration of the test equipment was conducted to find an equation relating air pressure and projectile velocity. Specimens ($1000mm{\times}700mm$) having similar specifications with the front windscreens in metro and conventional trains were used to conduct impact tests with this equipment to research the impact characteristics of the screens according to the impact velocity.

철도차량 전면창유리 충격 시험 및 특성 파악을 위해 유럽 및 국내의 전면창유리 충격 시험 방법을 비교 검토하였다. EN 15152에 따른 고속철도차량의 전면창유리 충격 시험이 가능한 정도인 약 500km/h 속도로 충돌체를 발사할 수 있는 압축 공기식 충격 실험 발사 장치를 설계 및 제작하였으며, 이 발사장치의 충돌체 발사 성능 확인을 위해 속도 보정 실험을 실시하여 압축 공기에 따른 충돌체의 발사 속도 관계식을 도출하였다. 도시철도 및 일반철도에 사용되는 동일한 사양의 전면창유리 시편($1000mm{\times}700mm$)에 제작한 발사 장치를 이용해 충돌 시험을 수행하여 충돌 속도에 따른 시편의 충격 특성을 살펴보았다.
