John Korsgaard, Senior Director, Engineering Excellence hos LM Wind Power
While the rotation of the rotor of the wind turbine can be slowed by changing the pitch angle of the blades during aerodynamic braking, the rotor needs a mechanical main shaft brake to keep it stopped completely. Frictional force is an essential physics concept that will help explain the working mechanism of the main shaft…
Three different types of forces act on gears and bearings in a gearbox. They are gravitational forces, frictional forces, and contact forces. The most significant are contact forces, due to the magnitude of the contact stresses that these forces are generating on the surfaces of the moving parts during operation. Contact force occurs when the…
Wind Turbines are made of composite materials. The materials that form this composite are Resin Usually epoxy or polyester resin Fiberglass Balsa Wood Structural Foam Usually PVC Carbon Fibre
Peel-ply fabrics are indispensable materials in the manufacturing process of wind turbine blades. Peel ply is the name of the synthetic fabric that is placed on the surface of the composite of fibers and resin, in the vacuum infusion process or vacuum bag. Peel ply fabrics are generally made of polyamide (nylon) or polyester, in…
