This paper describes the development of a 6-component load cell with plate beams which may be used to measure forces Fx, Fy, Fz and moments Mx, My, Mz simultaneously in industry. We have analyzed the bending strains on the surface of the beams under forces or moments by using Finite Element Method and designed the sensing elements of 6-component load cell. We have also determined the attachment location of strain gages of each load cell and fabricated 6-component load cell. To evaluate the rated strain and interference error of each load cell, we have carried out characteristic test of 6-component load cell.

회전축의 정밀 토크 발생용 직류 발전기 제어장치의 설계 및 성능평가에 관한 연구
김갑순(G. S. Kim),강대임(D. I. Kang),안병덕(B. D. Ahn) Korean Society for Precision Engineering 1994 한국정밀공학회지 Vol.11 No.6
A DC generator control system was designed to control the torque of a rotating shaft precisely. The control system is composed of a strain gage type torque cell, a torque cell amplifier, a computer, a D/A converter, a error detector, a DC voltage amplifier and a resistor. The response test under unit step input and the dynamic stability test for the designed control system were carried out. It was confirmed that the settling time from the response test is about 4 s and the error from the dynamic stability test is less than 0.06% of rated output of torque cell. The designed control system may be used to control a DC generator which may be used to apply torque to a rotating shaft.

원격전송장치를 이용한 비접촉식 회전 토크 측정장치의 정확도 평가
김갑순(G. S. Kim),주지원(J. W. Joo),권영하(Y. H. Kwon) Korean Society for Precision Engineering 1994 한국정밀공학회지 Vol.11 No.1
This paper presents manufacturing and evaluation of a non-contact rotational torque measurement system which consists of torque cell, telemeter system, transmitter and receiver coil, transmitter, receiver and telemeter indicator. Static calibration test results show that the system has a maximum uncertainty of 0.5% or less. A standard calibration system for rotational torque is used to evaluate the measurement system. As a result, the maximum uncertainty for measuring rotational torque by this system is 2% or less. We may conclude that the measurement system is sufficient to measure rotational torque of shaft in industry.
