Definitions

  • blades undergo two types of testing, i.e., the static testing and fatigue testing to achieve the desired certification from certifying bodies.
  • static testing the blades are tested to determine whether they can withstand extreme design loads especially from the point of view of safety and strength characteristics, which are essential for a blade to withstand extreme weather conditions.
  • Static testing also helps in verifying the bucking stability in addition to measuring deflection, frequency and strain verification of the blades.
  • the at least one swiveling element is rotated based on a plurality of testing positions of the blade, i.e., flap-wise and edge-wise positions.
  • the blades are positioned vertically with respect to foundation of the testing apparatus which is placed horizontally to the ground surface.
  • the vertically positioned blades are rotated from one position to the other with the help of the swiveling element disposed between the blade mounting plate and the base plate of the testing apparatus.
  • the rotation of the blade enables shifting from one testing position to the other without having to disassemble and reassemble the blade from the blade mounting plate while shifting the testing position from edge-wise to flap- wise and vice versa.
  • the swiveling element is a rotatable bearing assembly.
  • the blade to be tested is capable of being mounted on top of a blade mounting plate.
  • the blade mounting plate is rotatably mounted to the base plate through a plurality of swiveling elements.
  • the plurality of swiveling elements is rotating bearing assembly disposed in the space between the base plate and the blade mounting plate.
  • the blade mounting plate is capable of being tilted by the actuation of the hydraulic jack, Which enables easy assembly of the blade on to the blade mounting plate.
  • the position of the blade can be shifted from the flap-wise direction to the edge-wise direction.
  • the blade position can be changed for fatigue testing after completion of static testing.
  • a method for static and fatigue testing of a wind turbine blade 110 using the testing apparatus 100 is described.
  • the static testing of the blade 110 is performed at a testing position when the orientation of the blade is in a flap-wise direction. Similar static testing of the blade 110 is also performed at a testing position when the orientation of the blade is in an edge-wise direction.
  • the plurality of testing positions includes an inclined position of the blade. The inclination of the blade is controlled by the derrick structures using the one or more derrick control winch assemblies.
  • the method further includes shifting the blade 110 from one testing process, for example from the static testing to the fatigue testing.
  • the shifting is performed with the help of at least one swiveling element 108 that is disposed between the blade mounting plate 106 and the base plate 104.
  • the swiveling element 108 used for shifting the direction of the blade 110 is a rotatable bearing assembly.
  • the method further includes providing the plurality of testing positions using the at least one actuating element 202, the at least one derrick structure 112-1 and 112-2 and the at least one derrick control winch assembly 122, 124, and 126.
  • the actuating element 202 is a hydraulic jack that enables tilting of the blade mounting plate 106.
  • the hydraulic jack 202 tilts the blade mounting plate 106 such that the blade 1 10 can be mounted horizontally with the help of the derrick structures 1 12-1 and 1 12-2 with stay cables 206-1, 206-2, 206-3, 206-4, 206-5, and 206-6 fixed in required positions that acts as a crane hoisting the blade 110 using a crane hook 304, which is controlled by a crane hook actuation winch assembly 302.
  • the derrick structures 1 12-1 and 1 12-2 are made of high strength material that the derrick structures 1 12-1 and 1 12-2 can handle the loading, unloading and assembly of the blade 1 10 in the testing apparatus 100.
  • the derrick structures 112-1 and 1 12-2 of the present subject matter eliminates the need for a separate crane to be employed in the testing facility for loading/unloading/assembly of the blade 1 10 thereby providing a cost effective testing apparatus 100.

Abstract

L'invention se rapporte à l'essai statique et de fatigue de pales d'éolienne. Dans un mode de réalisation, l'invention concerne un appareil d'essai (100) destiné à l'essai statique et de fatigue d'une pale (110) d'éolienne. L'appareil d'essai (100) comprend une fondation (102) disposée sensiblement parallèle à une surface du sol, et une plaque de base (104) sensiblement coplanaire par rapport à la surface du sol et placée au-dessus de la fondation (102). Une plaque de fixation de pale (106) est montée rotative sur la plaque de base (104) et est apte à recevoir la pale (110) verticalement au-dessus de la surface du sol, dans un plan sensiblement perpendiculaire par rapport à la surface du sol. La plaque de fixation de pale (106) peut tourner au-dessus de la plaque de base (104) de façon à offrir une pluralité de positions d'essai de la pale (110) d'éolienne.
