The Association of German Engineers has approved standard values for vibration in wind energy turbines. “The vibration stress on parts and components of wind power plants is extremely high and causes damages in the millions,” says a press release. More than 450 onshore wind power plants with power outputs below 3 MW were analyzed. The guideline, “Measurement and evaluation of the mechanical vibrations of wind energy plants and their components,” is issued by the VDI Society for Development, Design and Marketing. A German/English version is available.  E-mail foreignsales@beuth.de, tel. +49 30 2601-2759, www.beauth.de
