Keywords: Attack angle, blade design optimization, wind turbine, fixed-pitch, variable-speed
Abstract The purpose of this paper is to find the optimum design attack angle for fixed-pitch variable-speed wind turbine blade design, given the base-line wind turbine and the blade airfoil.
One of the major Research and Design areas for innovative wind turbine technologies is the blade design optimization, such as the determining of the optimal composite material [1], and the vibratory load reduction [2].

At present, the mostly used method for cranes’ fatigue analysis is the nominal stress method: First, based on the S-N curve of the material, considering relevant influence coefficients, the S-N curve of the structure is obtained.
(2) Equivalent stress spectrum Generally, the material’s resistance index is obtained under symmetric cyclic load with zero mean, while the stress spectrum under random load has the mean of not zero.
In this study, the material of the container crane’s key structures is Q235, the coefficients m and C are usually given the values of -4.7059 and 14.357, respectively.

Where, D is the damage degree, is the action times under stress, and is the cycle number under action of stress.
