| titleOfInvention | How to design high-rigidity blades based on random isogeometric analysis |
| abstract | PROBLEM TO BE SOLVED: To provide a method for designing high rigidity of a blade based on random isogeometric analysis. The method creates a random field model of its material attributes and external load according to the manufacturing conditions and usage environment of the blade, and then meets the design demand for high rigidity of the blade and the lift-drag ratio constraint conditions. Create the optimal design model accordingly and solve the model. In the process of solving, the random isometric analysis method was used to calculate the random displacement of the blade under the influence of material attributes and the randomness of the external load, as well as the maximum lift-drag ratio of the blade airfoil. By calculating the fitness of the individual in the population, the design of high rigidity of the blade is realized on the premise that the lift-drag ratio is guaranteed. According to the present invention, the random displacement of the blade is calculated using a random isogeometric analysis method based on the discrete scheme of the base vector of the random Krylov subspace, taking into account the material attributes of the blade and the randomness of the external load. , Highly accurate blade random displacement can be obtained efficiently.
