Abstract

This study proposes an image composition technique based on convolutional neural networks (CNNs) to construct a surrogate model for predicting fan plots of three-dimensional (3D) composite blades, which represent natural frequency lists at different rotational speeds. The proposed method composes critical 2D cross-section images to improve the accuracy of the model. Numerical examples with various compositions of cross-section images are presented to demonstrate the efficacy of the CNN model. Additionally, gradient-weighted class activation mapping analysis is used to reveal the relationship between the internal structure of the blade and the fan plots. The study shows that using multiple images in the image composition technique improves the accuracy of the model compared to using single or fewer images. Overall, the proposed method provides a promising approach for predicting fan plots of 3D composite blades using CNN models.
考虑复合叶片的转子系统风扇图的卷积神经网络图像合成代理建模
本文提出了一种基于卷积神经网络(cnn)的图像合成技术,构建了一个替代模型,用于预测三维复合叶片的风扇图,该模型代表不同转速下的固有频率列表。该方法通过合成临界二维截面图像来提高模型的精度。通过不同截面图像组成的数值算例,验证了CNN模型的有效性。此外,利用梯度加权类激活映射分析揭示了叶片内部结构与风扇图之间的关系。研究表明,在图像合成技术中使用多幅图像比使用单幅或更少的图像提高了模型的准确性。总的来说,本文提出的方法为利用CNN模型预测三维复合材料叶片的风扇图提供了一种很有前景的方法。
