Structural behavior of a tubular wind tower for a 1.5 mw turbine

Resumo

Even though strong winds are not frequent in Brazil, many places, some along the costal shore, provide a potential to place eolic parks. In this work a tubular tower for a particular application is designed under some premises. In particular commercial sizes for sheet metal are chosen. Easy of transportation and assemblage are also considered. The dimensioned structure is then submitted to a static analysis using finite elements. Safety factors relative to inelastic behavior and instability are verified. Natural frequencies and the corresponding natural modes are also determined. Overall the structure is shown to satisfy functional requisites, but other evaluations are still pending.
