The invention provides a wind power generator blade bending-torsional coupling vector measuring device comprising a clamping mechanism, a load applying mechanism and a measurement performing mechanism. The clamping mechanism is matched with the root cylinder of a measured blade. The load applying mechanism is matched with the blade tip of the measured blade. The measurement performing mechanism comprises displacement sensors, force sensors, a static strain measuring system and a computer. The displacement sensors are distributed at the front end and the rear end of the cross sections of different positions of the measured blade. The force sensors are installed on the load applying mechanism. The input end of the static strain measuring system is connected with the displacement sensors and the force sensors, and the output end is connected with the computer. Accurate measurement and calculation of the bending-torsional coupling characteristic of the blade can be realized before installation of a wind power generator so that reliable operation of the wind power generator can be guaranteed.
