Abstract

본 발명은 자동차 주위에 공기가 흐르는 방향을 보거나 풍속의 분포와 표면압력 분포를 조사하여 항력특성을 향상시킬 수 있도록 실험하는 스트링바(String-bar)를 이용한 자동차 항력 측정장치에 관한 것이다.The present invention relates to a vehicle drag measurement apparatus using a string bar (String-bar) for experimenting to improve the drag characteristics by looking in the direction of air flow around the vehicle or by examining the distribution of wind speed and surface pressure distribution.

이와 같은 본 발명은 풍동의 수축부에 항력측정을 위해 고정설치한 강체막대와, 상기 강체막대 상,하에 설치하여 항력성분을 감지하는 스트레인 게이지와, 상기 강체막대에 링 형상으로 스토퍼 상단에 끼운 높이조절구와, 상기 높이조절구와 자동차를 연결하여 자동차의 항력을 전달토록 하는 스트링바와로 구성됨을 특징으로 한다.As described above, the present invention provides a rigid rod fixed to the contraction portion of the wind tunnel for strain measurement, a strain gauge installed above and below the rigid rod to sense drag components, and a height fitted to the top of the stopper in a ring shape on the rigid rod. It is characterized in that it comprises a control bar, and a string bar to connect the height adjustment sphere and the car to transmit the drag of the car.
