Modal testing of a simplified wind turbine blade

Tartibu, LK; Kilfoil, M; Van Der Merwe, AJ (International Journal of Advances in Engineering & Technology (IJAET), 2012)

This paper examines the modal analysis techniques applied in experiments using a uniform and a stepped beam. These simplified shapes are representative of the a wind turbine blade. Natural frequencies have been identified, ...
Vibration analysis of a variable length blade wind turbine

Tartibu, LK; Kilfoil, M; Van Der Merwe, AJ (IJAET, 2012)

In this paper, flap-wise, edge-wise and torsional natural frequencies of a variable length blade have been identified. Therefore designers can ensure that natural frequencies will not be close to the frequency of the main ...
