Abstract

This paper describes a research carried out for the design of a wind mill tower reduced-scale model to be built and tested in the boundary layer wind tunnel at the University of La Coruña. It is well known that one of the many requirement of a reduced-scale model is its capability of reproduce the natural frequencies and vibration modes of the real structure. In this research, this is achieved by using a technique developed by the authors in a previous work and adapted to this particular case. This technique is based on the use of optimization algorithms, allowing the minimization of the error between these dynamic properties of the reduced-scale model and the target values. The numerical results are presented.
