Zusammenfassung:	Provided is an apparatus for simulating an abnormal operation of a rotary system. The apparatus comprises: a motor; a coupling for coupling a shaft of the motor to a rotary shaft; the rotary shaft; a rotor connected to the rotary shaft and configured to simulate rotor unbalance; two or more journal bearing housings including journal bearings located on both sides in the direction of the rotary shaft of the rotor and supporting the rotary shaft; an oil feeder for supplying oil to the journal bearings; and a misalignment simulator disposed on the radially outer surface of the journal bearing housing to simulate rotary shaft misalignment by applying a predetermined magnitude of force to the journal bearing housing. Thus, the present invention simulates various misalignment and imbalance types and quantifies the degree of misalignment and imbalance to facilitate data analysis. 회전 시스템의 비정상 거동 모사 장치가 제공된다. 장치는, 모터, 모터의 축과 회전축을 연결하는 커플링, 회전축, 회전축에 연결되고 로터 불평형을 모사할 수 있도록 구성된 로터, 로터의 회전축 방향 양측에 위치하여 회전축을 지지하는, 저널 베어링이 포함된 2 이상의 저널 베어링 하우징, 저널 베어링에 오일을 공급하는 오일 공급 장치 및 저널 베어링 하우징의 반경 방향 외부 표면에 배치되어 저널 베어링 하우징에 소정 크기의 힘을 가함으로써 회전축계 오정렬을 모사할 수 있는 오정렬 모사 장치를 포함한다. 따라서, 다양한 오정렬 및 불평형 유형을 모사하고 오정렬과 불평형의 정도를 정량화하여 데이터 분석을 용이하게 할 수 있다.
