Our next international VDi top Conference for you

DRiVe tRAiNS Of WiND tuRBiNeShamburg, GermanyJune 19th and 20th, 2012

Because of the continuously rising importance of wind power to the energy mix, the issue of reliability is creeping up the agenda. therefore serious sums are invested in the development of drive train concepts which will push wind turbines into a new phase of improvement and enhance their reliability – driving down the cost of wind power as a result.the conference covers all aspects of Drive trains of Wind turbines and will present the latest state of knowledge with a special focus on: • Design requirements made on the components of drive trains

with gearings• Success factors for drive trains featuring high technical

reliability • Damage types in wind turbines and their root causes• Design, dimensioning and calculation of gearings and bearings• Modern simulation methods to determine realistic load
