Problems solved by technology

[0002] As a key component for capturing wind energy, the fan blade is a large composite material structure. The composite fiber layup structure is complex, and its performance varies with different layup angles, layup sequences and layup thicknesses, making blade design extremely complex. and difficulties. Using traditional modeling methods, even an experienced blade design engineer has to repeatedly design layups and establish a large number of finite element models for comparison and calculation to obtain a better design plan. However, if he wants to get the optimal solution , an almost impossible task

Abstract

The invention discloses a wind turbine blade laying design method for a wind generating set. The method comprises the following steps that (1) a blade geometric model is built; (2) establishing an initial layer laying model, and respectively establishing a beam cap secondary layer laying model, a shear web secondary layer laying model and a shell secondary layer laying model on the initial model;(3) carrying out IFF (inter-fiber failure) analysis; (4) calculating the laying area; (5) summarizing the relation between the blade IFF coefficient and the laying layer and the relation between the blade laying layer and the weight; (6) carrying out fiber cloth laying optimization design; (7) carrying out blade core material optimization design by taking the blade buckling safety coefficient as design constraint and taking the minimum mass as a design target; and (8) carrying out lamination design, finite element checking and drawing according to the technical requirements of blade design specifications, manufacturing processes and the like. According to the method, the optimal solution is searched in the whole domain range, so that the blade laying layer is optimized, the blade quality is reduced, complex design and checking processes are avoided, and the research and development efficiency is improved.

Description

technical field [0001] The invention relates to the field of fan blade design, in particular to a layer design method for wind rotor blades of a wind power generating set. Background technique [0002] As a key component for capturing wind energy, the fan blade is a large composite material structure. The composite fiber layup structure is complex, and its performance varies with different layup angles, layup sequences and layup thicknesses, making blade design extremely complex. and difficulties. Using traditional modeling methods, even an experienced blade design engineer has to repeatedly design layups and establish a large number of finite element models for comparison and calculation to obtain a better design plan. However, if he wants to get the optimal solution , is an almost impossible task. Therefore, it is of great significance to study and design a method that can accurately and quickly obtain the optimal layup of blades. Contents of the invention [0003] Bas...
