Dynamics embedded softly

27.01.2011
Technical Conference „Drivetrains in wind power installations - requirements for gears, couplings and bearings“

The rapid developments in wind turbines should not mislead us to overlook the fact that often in turbines, particularly of high performance categories, technical faults and even damages occur in various elements of the drivelines (gears, couplings and bearings), which in drivelines of comparable size in other industries or branches of industry (e.g. heavy rolling mill drives) have so far been unknown.

The main reason for this, on the one hand, lies in the fact that the basic support structure of a wind turbine consisting of tower and nacelle are very elastic and in combination with the rotor presents an extremely oscillation-susceptible system. On the other hand, the quick growth of the industry in the past few years has certainly also brought forth problems, as neither an extensive operational experience with varying-sized turbines nor enough expertise, especially in the area of turbine drive trains, with the use today of large-sized components could be gathered.

After the experience of the past few years, with many failures, above all in the area of drivelines, increasingly greater importance is attached to reliability. Servicing and repairs of wind turbines are as a consequence of the difficult accessibility expensive and time consuming. Downtimes resulting therefrom reduce not only the energy yield but also diminish the net return. A reliable but nonetheless economic interpretation requires an exact knowledge of the operating loads and a safe protection from overloads. With the planned offshore turbines, reliability will gain a still further importance.

The objective of the two-day conference “Drivelines in wind power installations„ is to inform the delegates about the basic structure of wind turbines and the resulting demands put on the main driveline. Based on current damage images possibilities will be presented of stress and strain related assessments of gears, shafts and bearings in transmissions, taking into account the occurring dynamic loads. Modern methods for diagnosis of oscillations during operations as well as presentations on the current drive concepts and tribology round up the event.

The conference “Drivelines in wind power installations” will be held on 22 - 23 March 2011 at Haus der Technik in Essen and is aimed at Developers, designers of the manufacturers and suppliers, staff of the operators and power utilities, insurances, banks and experts. Simultaneous translation German/English will be provided during the symposium.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
