Geislinger’s drivetrain solutions effectively reduce noise emission from wind turbines

On May 19th, 2021, the Torsional Vibration Symposium webinar was successfully held with over 400 online participants from more than 50 countries. During the Symposium, Dr. Klaus Prenninger, Head of the Torsional Vibration Calculation team at Geislinger, informed the audience about emission reduction strategies for large bore combustion engines.
