Book Description
The Gearbox Reliability Collaborative (GRC) investigates root causes of wind turbine gearbox premature failures and validates design assumptions that affect gearbox reliability using a combined testing and modeling approach. Knowledge gained from the testing and modeling of the GRC gearboxes builds an understanding of how the selected loads and events translate into internal responses of three-point mounted gearboxes. This paper presents some testing and modeling results of the GRC research during Phase 1 and 2. Non-torque loads from the rotor including shaft bending and thrust, traditionally assumed to be uncoupled with gearbox, affect gear and bearing loads and resulting gearbox responses. Bearing clearance increases bearing loads and causes cyclic loading, which could contribute to a reduced bearing life. Including flexibilities of key drivetrain subcomponents is important in order to reproduce the measured gearbox response during the tests using modeling approaches.

Book Description
Die hohe Entwicklungsgeschwindigkeit im immer noch jungen Bereich Windenergie führt zu neuen Herausforderungen auf dem Gebiet der Antriebstechnik von Windenergieanlagen (WEA). Zur Gewährleistung und Erhöhung der Zuverlässigkeit von WEA, auch im Hinblick auf die geringe Langzeiterfahrung mit den aktuellen Leistungsklassen, ist es notwendig, Entwicklungen und Innovationen im Bereich von Regelungs-, Berechnungs- und Prüfverfahren voranzutreiben und neue Prüfmöglichkeiten zu erschließen. Im Rahmen der zweiten Conference for Wind Power Drives (CWD) am 3. und 4. März 2015 im Eurogress Aachen wird der neueste Stand der Forschung und Technik im Bereich der Triebstränge sowie Pitch- und Yawsysteme von Windenergieanlagen präsentiert. Die CWD versteht sich als interdisziplinäre Plattform zum Erfahrungs- und Ideenaustausch zwischen Entwicklern, Forschern und Anwendern und soll darüber hinaus die Kommunikation zwischen Industrie und Hochschule in der Windbranche fördern. The high speed of development within the still young sector wind energy leads to new challenges in the field of wind turbine (WT) drive trains. Regarding little long term experience with current WT power levels, developments in the range of control, design and test procedures must be furthered and new test facilities have to be made accessible to ensure and increase reliability of WT. To present the state of the art and innovations in the field of wind turbine generator drive trains and pitch-/ yaw-systems the second Conference for Wind Power Drives (CWD) will be taking place on 3rd and 4th of March 2015 in Eurogress Aachen. The CWD is designed as an interdisciplinary platform for knowledge and technology transfer between developers, research scientists and operators. Furthermore, the conference promotes exchange between industry and academia in the field of wind turbine drive trains.

Book Description
This book proposes the formulation of an efficient methodology that estimates energy system uncertainty and predicts Remaining Useful Life (RUL) accurately with significantly reduced RUL prediction uncertainty. Renewable and non-renewable sources of energy are being used to supply the demands of societies worldwide. These sources are mainly thermo-chemo-electro-mechanical systems that are subject to uncertainty in future loading conditions, material properties, process noise, and other design parameters.It book informs the reader of existing and new ideas that will be implemented in RUL prediction of energy systems in the future. The book provides case studies, illustrations, graphs, and charts. Its chapters consider engineering, reliability, prognostics and health management, probabilistic multibody dynamical analysis, peridynamic and finite-element modelling, computer science, and mathematics.
