Title: MEASUREMENT APPARATUS AND MEASUREMENT METHOD FOR CENTER OF GRAVITY OF BLADE FOR WIND POWER GENERATOR
Abstract:
The present invention relates to a measurement apparatus and a measurement method for the center of gravity of a blade for a wind power generator. The measurement apparatus comprises first and second weight measurement units, a distance measurement unit, and a controller. The first weight measurement unit has a root part of the blade seated thereon to measure the weight of the root part. The second weight measurement unit is placed to be spaced apart from the first weight measurement unit and has a tip part of the blade seated thereon to measure the weight of the tip part. The distance measurement unit measures a distance between an edge position of the root part and a weight measurement intermediate position of the root part and a distance between the weight measurement intermediate position of the root part and a weight measurement intermediate position of the tip part. The controller calculates the center of gravity of the blade on the basis of the measured weight data and the measured distance data.
