概要 |
This paper describes unique ideas and devices to accurately measure cable tension of ultra high voltage transmission line. The authors developed a manpower exciter named "YUSURU," which is characteriz...ed by light-weight, non-power, and application of bicycle mechanism. In a vibration test, the exciter was used to swing a transmission tower. A sensitive tension meter with the special specification was also employed to measure the cable tension. Based on the data obtained in the test, a numerical analysis was made into the dynamic properties of the transmission tower and line. It was revealed that the Nonlinear analysis result was nearly coincided with the vibration test result.続きを見る
