1 Medlemsmøde foråret 2012 Revision Gearbox testing Wednesday 23 rd May 2012 Members meeting at: SDU Auditorium SydDansk Universitet, Niels Bohrs Allé 1, 5230 Odense M Program Time 09:00 10:00 Welcome, registration, coffee & bread rolls 10:00 10:05 Welcoming speech and opening, by Chairman Ivan Hede 10:05 10:50 Testing of gearboxes at Vestas Wind Systems by Christian Fenselau, Vestas Wind Systems Testing of s gearboxes at Vestas Wind System. 10:50 11:35 Improving Gear Performance through Applied Gear Testing Research by Dr Brian Shaw, Director, Design Unit, Newcastle University, UK Characterising the suitability of modern gearing for demanding applications requires practical and cost effective means to generate performance data through realistic testing. This presentation will describe testing methodologies employed at Design Unit to explore research strategies to enhance the performance of gears through the use of modern materials, optimised designs, heat treatments and surface engineering approaches. Results from research performed to understand both contact and bending fatigue failure modes will be presented and trends for future research directions will be discussed. 11:35 12:00 Generalforsamling i se vedhæftede dagsorden Annual meeting, see attached agenda (in Danish) Frokost/lunch 13:00 13:45 Testing and validation of wind turbine gearboxes by Dr.-Ing. F.-D. Krull & Dr. R. G. Wittor, Eickhoff Antriebstechnik, Germany, This presentation contains testing and validation methods for design and calculation assumptions. This will be supported by system and gearbox simulation. Another focus will be on improved reengineered gearboxes based on lessons learned and testing. 13:45 14:30 Gearboxes for Wind Turbines - Development and Testing by Dipl.-Ing. Frank Kretschmann, Winergy, Germany Requirements for the development of gearboxes for wind turbines increase based on the experience made in the business since the 80's. These requirements are defined by certification bodies, turbine manufacturer as well as gearbox manufacturer. The development of wind power is determined by cost pressure especially for offshore application as the costs of exploration, production and connection are on a high level. To reduce live cycle costs intensive development and testing procedures prior to erection of turbines are necessary. The presentation describes the development process of gearboxes for wind turbines at Winergy beginning with the receipt of the specification from the turbine manufacturer followed by theoretical design of the mechanical components. Finally the presentation illustrates the standard testing procedure at Winergy. 14:30-14:45 Coffee break Medlemsmøde forår 2012 rev / 6

2 14:45 15:30 Prototype gear unit testing as a part of verification process at Moventas Wind R&D by Kari Uusitalo, Technology Specialist and Henna Haka Group Manager, Moventas Wind, Finland Testing of wind turbine prototype gear units at Moventas Wind R&D technology center includes a wide range of measurements according to different test procedures in various loading and climate conditions. Verification process leads to prototype acceptance and classification by validating the gear unit calculations and design. Continuous improvement of torque density of wind turbine gear units requires also continuous development of measurement methods. High torque combined to multiple splitted load paths inside the gear unit have generated several mandatory verification tasks to be implemented in prototype tests. The presentation demonstrates the typical measurements during the prototype tests with some examples of results, the test environments and some new technology research projects. 15: Testing of Convoloid Gear Forms in Wind Turbine Applications by Barney Berlinger, John Colbourne (Genesis Partners, USA), Mike Fish (Dontyne Systems UK) Genesis Partners (USA) has developed a 'Convoloid' gear form technology with advantageous contact conditions compared to Involute geometry enabling substantial reduction in size and weight over conventional Involute designs. Tests have been carried out on a 5MW single stage planetary gear drive (CGSPL014) for an offshore wind turbine generator. The CGSPL014 is a specific design example of Convoloid applied to larger WTG s. The presentation will illustrate that the GRI test gave substantial comfort that the Technology works. The economics of the application of the Technology (ONLY in the US market) is discussed. 16:15 16:30 Questions, discussion, proposals for next members meetings etc. Med venlig hilsen/best regards Bestyrelsen/The board Medlemsmøde forår 2012 rev / 6
