PROPOSAL OF ESTIMATION METHOD FOR FATIGUE DAMAGE ACCUMULATION WITH WIRELESS ACCELEROMETER FOR LIGHTING POLES

Abstract

 In this study, the estimation method of fatigue damage accumulation with wireless accelerometer for lighting pole was investigated. The acceleration and stress measurement for the lighting pole vibrated by vortex induced vibration was carried out. The results showed that the fatigue damage seemed to be cumulated at all times. Furthermore, the proposed estimation method of fatigue damage accumulation based on the acceleration measurement was proposed. By applying the proposed method, the damage accumulation was almost same as that obtained by the stress measurement.
