Abstract: Based on the characteristics of the two models,a mixed beam-shell model is created.Taking DTU 10 MW blade as an example,the three models are compared in terms of modal frequency,deformation,stress,strain and computational efficiency respectively.The results show that the mixed beam-shell model has a boundary effect near the combined position,which leads to distortion of the results in this area,while other areas maintain high accuracy.Meanwhile,the mixed model is of high efficiency,which can provide guidance for design and structural analysis of wind turbine blades.
