Abstract

본 발명은 철도차량 대차프레임의 하중시험장치에 관한 것으로, 대차프레임(3)에 하중을 가하는 유압실린더(4)에 공급되는 압유량이 전자비례제어밸브(2)를 통해 제어되어지도록 되어 있으면서, 이 유압실린더(4)와 대차프레임(3)사이에 하중의 크기를 측정하기 위한 로드셀(5)이 설치되어 있으면서, 상기 로드셀(5)과 대차프레임(3)에 설치된 응력게이지(6)의 출력신호가 데이터처리기(7)에서 처리되어 정확한 하중과 그에 따른 응력을 측정할 수 있게 주도록 된 것이다.The present invention relates to a load testing apparatus for a railway vehicle bogie frame, wherein the hydraulic oil pressure supplied to the hydraulic cylinder (4) applying the load to the bogie frame (3) is controlled through an electromagnetic proportional control valve (2), The output of the stress gauge 6 provided in the load cell 5 and the bogie frame 3 while the load cell 5 for measuring the magnitude of the load is provided between the hydraulic cylinder 4 and the bogie frame 3. The signal is processed in the data processor 7 so that the correct load and the resulting stress can be measured.
