METHOD AND SYSTEM FOR MEASURING A PERPENDICULAR WIND COMPONENT

摘要

The present invention concerns a method for measuring a perpendicular wind speed component with respect to a suspended cable span (2) comprising the steps of monitoring a motion of at least one point of said suspended cable span (2) over a time interval and determining whether said motion comprises an Aeolian vibration. If said motion is not determined to comprise an Aeolian vibration a transverse swing angle of the suspended cable span (2) is measured and said perpendicular wind speed component is calculated as a function of said transverse swing angle whereas if said motion is determined to comprise an Aeolian vibration a frequency of said Aeolian vibration is measured and said perpendicular wind speed component is calculated as a function of said Aeolian vibration frequency.
