摘要： A method for stiffening a wind turbine tower employing fingerplate assemblies on flangeless joints between adjacent tubular tower sections. The method includes limiting the intercan gap between adjacent end surfaces of the tower sections at the flangeless joints and selecting a number of fingerplates to fasten each flangeless joints to limit distortion. Establishing dimensions for the fingerplates may further minimize localized tower distortion. Selecting a material for the fingerplate with a lower Young's modulus than a material for the tubular section also results in reduced localized tower distortion. Attaching a coverplate to a top tubular section limits tip displacement for the tower.

摘要： A system for laser shock peening includes a laser positioned to direct a laser pulse at a first side of a work piece and a coupler on a second side of the work piece. The system further includes a Doppler shift detector positioned to measure a velocity of the coupler. A method for laser shock peening includes depositing an amount of energy from a laser pulse into a first side of a work piece and transmitting a pulse having a first frequency at a second side of the work piece. The method further includes receiving a reflected pulse having a second frequency from the second side of the work piece and determining the velocity of the work piece based on the difference between the first frequency and the second frequency.

摘要： An extrusion die for radial extrusion of a rotor shaft for a wind turbine generator has a body and a mandrel received in the body. The mandrel and body cooperatively define a tubular interior chamber. A punch is received in the tubular interior chamber and is moveable with respect to body and mandrel. A radial extrusion insert has a radial interior chamber in communication with the tubular interior chamber. The radial extrusion insert includes an arcuate edge disposed in a transition area between the tubular interior chamber and the radial interior chamber.
