| Abstract: | Based on the mechanical model of cable vibration, the mathematical relationship between frequency and cable tension is established. Using the measured natural frequency, the cable tension and order of natural frequency are calculated, and a method to assess an assessment method for the reliability of the results is given. A new type of cable tension tester is developed for a cable vibration characteristics and cable tension measurement application environment. The practicality and reliability of the tester has been verified in practical engineering applications. |
