Non-Contact Spatial Vibration Measurement of Cable with a Small Sag: OMA Application for Tension Force Estimation
This paper presents a method for estimating the tensile force in a cable with a small sag (0 ≤ d/L ≤ 1/8) based on analytical calculations and Operational Modal Analysis (OMA) using non-contact displacement sensors. The in-plane and out-of-plane natural frequencies, as well as the mode shapes, were identified and subse...
