Beschreibung
Zusammenfassung:	According to the present invention, provided is a multifunctional material fatigue test device comprising a driving part, and a specimen holder for a bending test in which one end of a specimen is fixed for a bending fatigue test; and the driving part comprises a rotating member rotated by a driver, a mover which applies a deformation to the specimen by linearly reciprocating along a rail part, and a connecting rod connecting the rotating member and the mover to convert the rotation of the rotating member into the linear reciprocating motion of the mover. Therefore, the present invention is capable of adjusting a radius of curvature of the specimen during the bending fatigue test. 본 발명에 의하면, 구동부; 및 굽힘 피로 시험을 위해 시편의 일단이 고정되는 굽힘 시험용 시편 고정구를 포함하며, 상기 구동부는, 구동기에 의해 회전하는 회전부재와, 레일부를 따라서 직선왕복이동하여 상기 시편에 변형을 가하는 이동자와, 상기 회전부재와 상기 이동자를 연결하여 상기 회전부재의 회전을 상기 이동자의 직선왕복운동으로 변환시키는 커넥팅 로드를 구비하는 다기능 재료 피로 시험 장치가 제공된다.
