The research network TremAc was initiated by the southern German research cluster WindForS. In this case, a single modeling chain is intended to calculate the calculation models for all vibrating plant components and the environment, ie rotating rotor blades, drivetrain, gondola suspension and tower structure, base and subsoil with various topographical forms as well as air to nearby residential buildings and workplaces. The developed computational models are to be validated with measurements of sound emissions and immissions as well as seismic waves in the soil of a single wind turbine and in a wind farm. At the same time, residents are to be interviewed with the help of environmental medical and psychological questionnaires, and subjective complaints are to be correlated with objective measurements in buildings.
