Abstract
본 발명은 피 체력룸을 적정한 수준으로 체결할 수 있는 볼트의 축력을 측정하기 위한 것으로서, 볼트의 생크 부위에 180°위상으로 2축용 스트레인 게이지를 부착하여 폴 브리지 타입 휘스톤 브리지를 형성하고, 그 기전력을 측정하여 볼트의 축력을 산출할 수 있도록 함으로써, 볼트의 로컬 밴딩 효과 및 온도 영향에 따른 측정 오류가 방지될 수 있어 보다 정확한 축력 측정이 가능함과 동시에 엔진과 같은 열적 변화가 심한 측정물에서도 그 온도 영향이 보상되어 피측정물의 작동중에도 정확한 축력 측정이 가능한 이점이 있다.The present invention is to measure the axial force of the bolt that can tighten the fitness room to an appropriate level, to form a pole bridge type Wheatstone bridge by attaching a two-axis strain gauge at 180 ° phase to the shank portion of the bolt, By measuring the electromotive force, it is possible to calculate the axial force of the bolt, which prevents the measurement error caused by the local banding effect of the bolt and the temperature effect, which enables more accurate axial force measurement, and it is also possible to measure even the severe thermal changes such as the engine. The effect of temperature is compensated for, allowing accurate axial force measurement during the operation of the workpiece.
