The present invention relates to a resistance measurement system for model ship testing, which can be applied in various maritime conditions. The resistance measurement system comprises: a resistance measurement unit which is connected to a towing rod extending from a model ship, and measures the resistance acting on the model ship in still water and in waves through a load cell; a load buffering unit which is placed on a fixing device extending from a measurement frame of a towing carriage for towing the model ship, and elastically supports the resistance measurement unit through an elastic member to buffer the load applied to the resistance measurement unit; and a parallel point correction force application unit which is placed on the measurement frame of the towing carriage for towing the model ship, and applies a load to the resistance measurement unit through cable connection to guide the resistance measurement unit coupled to the load buffering unit to a parallel point of oscillation induced by waves. 본 발명은, 모형선으로부터 이어지는 예인봉에 연결 설치되되, 로드셀을 통해 정수 중 및 파랑 중 상태에서 모형선에 작용하는 저항을 측정하는 저항측정유닛; 상기 모형선 예인을 위한 예인전차의 측정프레임으로부터 이어지는 고정장치에 배치되되, 탄성부재를 통해 상기 저항측정유닛을 탄력적으로 지지하여 상기 저항측정유닛에 가해지는 하중을 완충하는 하중완충유닛; 및 상기 모형선 예인을 위한 예인전차의 측정프레임에 배치되되, 케이블 연결을 통해 상기 저항측정유닛에 하중을 부여하여 상기 하중완충유닛에 결합된 상기 저항측정유닛을 파랑에 의한 전후동요 평행점으로 유도하는 평행점 보정력 인가유닛;을 포함하는 것을 특징으로 하는 다양한 해상 상태에서 적용 가능한 선박의 모형시험용 저항 계측 시스템에 관한 것이다.
