The present invention relates to a device and a method for self-diagnosis of abnormality of a damper, and more specifically, to a device and a method for self-diagnosis of abnormality of a damper for diagnosing, in real time, a failure of a damper installed to attenuate vibration of a railway vehicle while driving. The present invention relates to a device for self-diagnosis of abnormality of a damper for diagnosing an abnormality of a damper provided in a railway vehicle, including: a load sensor and a speed sensor which are provided between an outer cylinder and a joint of the damper or between an inner cylinder and the joint; and a diagnostic unit for diagnosing the state of the damper by calculating a speed and a load from a signal sensed from the sensor.

    본 발명은 댐퍼 이상 자가진단 장치 및 방법에 관한 것으로, 주행 중 철도차량의 진동을 감쇠하기 위하여 설치된 댐퍼의 고장을 실시간으로 진단하기 위한 댐퍼 이상 자가진단 장치 및 방법에 관한 것이다. 본 발명은 철도차량에 구비되는 댐퍼의 이상여부를 진단하는 댐퍼 이상 자가진단 장치에 있어서, 상기 댐퍼의 외통과 조인트 사이 또는 내통과 조인트의 사이에 하중센서 및 속도센서가 구비되며, 상기 센서로부터 감지한 신호로부터 속도 및 하중을 계산하여 댐퍼의 상태를 진단하는 진단부를 포함하여 이루어지는 것을 특징으로 한다.
