Description
technical field [0001] The invention belongs to the technical field of modeling, and in particular relates to a parametric modeling and calculation analysis method for a pre-embedded blade root of a wind power blade. Background technique [0002] The blade root connection model of embedded bolt sleeves is relatively complex. In the blade root connection design stage, it is usually necessary to calculate the connection strength of the blade root under the combination of multiple typical parameters. Therefore, multiple finite element models of the blade root connection need to be established separately. As a result, the optimal blade-root connection design scheme was obtained. [0003] The current modeling method is usually to establish multiple finite element models of embedded bolt-sleeve blade root connections through GUI operations, and finally select the optimal design scheme through the comparison of finite element calculation results. However, modeling through GUI is ti...
