Abstract

본 발명은 착탈이 용이하고 시험차량의 무게를 정확하게 설정할 수 있도록 된 1/4차 능동현가장치시험기에 관한 것으로, 지지플레이트위에 주프레임과 부프레임이 소정간격을 두고 좌우에 각각 1쌍씩 설치됨과 더불어, 상기 주프레임의 하부에 부미끄럼베어링을 매개로 상하미끄럼이동할 수 있도록 설치된 샤시질량부재와 유압원과 연결된 서어보밸브를 갖추고서, 이 샤시질량부재를 소정진동수로 가진시킬 수 있도록 된 진동 발생수단과, 주프레임의 상부에 주미끄럼베어링을 매개로 상하미끄럼이동할 수 있도록 설치된 차체질량부재와 이 차체질량부재위에 선택적으로 부가되는 차체무게증분질량체로 이루어진 가압수단 및, 상기 차체질량부재에 설치된 가속도센서와 상기 샤시질량부재에 장착된 변위센서 및 상기 차체질량부재와 샤시질량부재를 연결시키는 연결봉을 갖추고서 이 연결봉에 의해 변위량이 측정된 값을 입력받아 상기 진동발생수단과 가압수단사이에 설치되는 능동액튜에이터의 유압을 제어하는 제어장치를 갖춘 구조로 되어 있다.The present invention relates to a 1 / 4th order active suspension tester which is easily detachable and accurately sets the weight of a test vehicle. The main frame and the subframe are provided on the support plate at a predetermined interval, one pair on each side. Vibration generating means having a chassis mass member and a servo valve connected to a hydraulic source, which are installed to move up and down by means of a sub-sliding bearing at the lower part of the main frame, to excite the chassis mass member at a predetermined frequency. And a pressurizing means consisting of a body mass member installed on the upper part of the main frame by means of a main slide bearing, and a body weight incremental mass selectively added to the body mass member, and an acceleration sensor installed on the body mass member. And a displacement sensor mounted on the chassis mass member and the body mass member and the chassis mass member. It is provided with a connecting rod for connecting and receives a value measured by the displacement rod is a structure having a control device for controlling the hydraulic pressure of the active actuator installed between the vibration generating means and the pressing means.
