Nacelle test apparatus

摘要

A nacelle test apparatus for testing a wind turbine nacelle is provided. The test apparatus includes a physical tower model apparatus realized to model the behavior of a wind turbine tower and/or a physical rotor model apparatus realized to model the behavior of a wind turbine rotor, and an exciter apparatus for exciting a physical model apparatus. Also provided is a method of testing a wind turbine nacelle, which method includes mounting the nacelle onto a physical tower model apparatus of a nacelle test apparatus, which physical tower model apparatus is realized to model the behavior of a wind turbine tower, and/or mounting a physical rotor model apparatus of the nacelle test apparatus to a hub of the nacelle, which physical rotor model apparatus is realized to model the behavior of a wind turbine rotor, and exciting the physical tower model apparatus and/or the physical rotor model apparatus.
