Comparison of laser technology & strain gauge application technology for measurement of interaction force between wheel and rail

차륜/레일 작용력 측정을 위한 레이저기술과 스트레인게이지 응용기술 비교

Korea Railroad Research Institute(KRRI) propelled sensing and measurement techniques development for measure of Lateral Force and Vertical Force With Italy to international cooperation research project for laser technology for measurement of wheel/rail interaction force. In this paper, we compared the laser technology for measurement of wheel/rail interaction force with the existing method. And then, we suggests interaction force measurement system procedure of hereafter.
