Abstract:

Acceleration measurement is widely employed in various engineering field, because acceleration sensors generally have low noise and cost effective. Recently, FFT analysis of measured acceleration data is widely used to determine cable tension. This study proposes a stay cable measurement system using acceleration data to determine the cable tension and vibration amplitude. Real vibration amplitude can be estimated with this system by taking the vector summation of the plane (2-axis) displacements measured simultaneously. A small light-weight wireless sensor and cable climbing robot are also proposed to increase the applicability.
