Abstract

In order to improve the structural design of steel towers for wind turbines, and in order to allow for detailed structural optimizations, a methodology is needed which allows for quick and reliable considerations of the complex dynamic load situations. Whereat for the design of details for the machinery and the blade optimization time domain methods using multi-body-simulations are well established, their usage is often to extensive due to the needed level of detail to use them for an iterative tower design. Especially with regard to lattice towers, it is therefore desirable to investigate faster stochastic methods which focus on the overall dynamic behaviour based on the probability of structural stresses within the tower construction.
