A Study on the Tension Measurement of External Tendon Using Vibration Method

초록

In this study, natural frequency of the tendon is measured using acceleration sensors. Estimation of the tendon tension is performed by using many types of solutions such as string theory equation, stiff string with clamped-clamped boundary conditions. The results are compared with the measured value of load cell data. As a result, stiff string equation with clamped-clamped boundary conditions is more accurate than the other methods.
