Dear All,


When wind turbine rotor rotates it's blades especially blade roots undergo cyclic stresses. These stresses are due to gravitation forces and inertial forces.


Could any body of you explain me how these cyclic forces vary? I am interested to know the basic mechanics of these forces for example what would be the stress level in a blade root when the blade is perpendicular to group (pointing towards ground or sky), or the stress level when a blade is horizontal etc....(I am not much interested in Aerodynamics forces, since for steady mean wind flow they are constant)


Apart from basic mechanics of these stresses I would also like to go in the details of mathematical analysis of this phenomenon. So could you please suggest me some good reference book, lecture notes or any other written material.


thanks a lot in advance,
regards, Milind.
