New wind energy solution, LMS Virtual.Lab Aerodyn Wind Loads, to be presented at EWEC 2009


Time-saving feature helps wind turbine engineers takes the guesswork out of wind turbine design

Leuven , Belgium – March 10, 2009 – LMS, the engineering innovation company, is pleased to announce that it will be participating in EWEC 2009, Europe’s premier wind energy event. At EWEC 2009, which attracts leading renewable energy experts from around the world, LMS will present several of its dedicated wind energy solutions for wind turbine manufacturers, including the new LMS Virtual.Lab Motion Aerodyn Wind Loads feature found in its latest release, LMS Virtual.Lab Rev 8B.

Unlike other industries, wind turbine developers face some very particular challenges like aero-elastic wind load modeling, automating numerous and varying load runs and comprehensive pre- and post-processing. To solve this previously, users had to rely on specialized third party software outside the LMS Virtual.Lab environment and the related time-consuming data translations and importation, but thanks to this new feature in LMS Virtual.Lab Rev 8B -- LMS Virtual.Lab Motion Aerodyn Wind Loads, users will be able to reliably predict transient dynamic loads and use them as input for subsequent fatigue-life and radiated noise emission calculations – all from within the LMS Virtual.Lab environment.

An ideal environment for 3D studies with control system functionality, LMS Virtual.Lab Motion can easily be used to create the blade and its structural flexibility and the wind behavioral traits, incorporating the modeling of any other critical elements in appropriate detail, such as gearboxes, bearings and controls. The wind loads themselves are computed using the Aerodyn subroutine for LMS Virtual.Lab Motion. Numerous pre-processing options are available to help create correctly formatted wind input data and include wind behavior traits ranging from turbulent to constant and even IEC wind standards to validate the wind turbine design. Based on this wind information and the blade orientation and speed during each time step, the LMS Virtual.Lab Aerodyn subroutine takes over, calculating the apparent wind speed on the blades and the precise subsequent wind load for each blade section enabling accurate dynamic simulation studies in LMS Virtual.Lab Motion.

“We integrated the Aerodyn functionality used to apply accurate loads on a turbine into our advanced 3D multi-body code to model the entire wind turbine interaction with the wind in a much more scalable way. An easily accessible 3D environment for cross-attribute multi-disciplinary simulations, LMS Virtual.Lab is the only 3D CAE environment that addresses the specific challenges of wind turbine design including precise blade-wind interaction and load cascading thanks to the new Aerodyn Wind Loads feature,” concluded Guillaume Lethé, Product Manager, LMS Virtual.Lab Motion.

LMS International will be present at the European Wind Energy Conference and Exhibition (EWEC) in Marseille, France from March 16th - March 19th, 2009. Please feel free to visit our stand #1736 in Hall One.

In addition, LMS will be holding a press conference in the EWEC Press Center on Tuesday, March 17th at 15:00. Our wind energy and testing, simulation and service experts will be available for interviews.

About LMS’ Wind Energy Solutions

The growing demand for wind energy has greatly advanced the technologies applied in wind turbine development over the past decade. But engineering new wind turbines remains a complex and challenging task, due to the large physical size, the complex interaction between mechanical and electro-mechanical subsystems, and the strongly varying wind speed.

To certify a new wind turbine, manufacturers must ensure full system reliability under real-life operating condition. Durability must be assessed to provide a 20-year lifetime with low operation and maintenance costs. Noise emissions must remain within prescribed tolerances. On top of that, the control system must guarantee clean voltage at constant frequency. Overcoming these challenges involves extensive engineering efforts from initial concept design to final wind turbine validation and certification.

LMS has worked extensively with wind turbine manufacturers and suppliers to help engineer top-class products. For wind turbine manufacturers, LMS offers an extensive portfolio of simulation tools, testing systems and dedicated services for specific wind energy issues ranging from vibro-acoustic measurements and analysis to fatigue engineering and noise optimization to complete multi-domain system simulations for mastering mechanical, electrical and thermal effects.
