Abstract

Abstract: In order to design full-scale blade static test specification quickly, a beam model with geometry nonlinear analysis method which was used for static test design is presented based on ANSYS. First, compared with shell model, the accuracy of beam model was verified. Then, the method was used in the full-scale blade static test. The test result reveals that the test data is coincided with the calculated data and derivation meets requirements of guideline. So the feasibility of this method was verified.

Key words: full-scale blade, static test, beam model, nonlinear analysis, composites
