Kinematic analysis of structural mechanics based on convolutional neural network
This work addresses kinematic analysis in structural mechanics, potentially aiding engineers, but it is incremental as it applies an existing CNN method to a new domain-specific dataset.
The researchers tackled kinematic analysis of plane bar structures using a convolutional neural network (CNN), achieving 100% accuracy on training, validation, and test sets, and 93.7% on an additional test set, demonstrating that CNNs can learn structural mechanics knowledge.
Attempt to use convolutional neural network to achieve kinematic analysis of plane bar structure. Through 3dsMax animation software and OpenCV module, self-build image dataset of geometrically stable system and geometrically unstable system. we construct and train convolutional neural network model based on the TensorFlow and Keras deep learning platform framework. The model achieves 100% accuracy on the training set, validation set, and test set. The accuracy on the additional test set is 93.7%, indicating that convolutional neural network can learn and master the relevant knowledge of kinematic analysis of structural mechanics. In the future, the generalization ability of the model can be improved through the diversity of dataset, which has the potential to surpass human experts for complex structures. Convolutional neural network has certain practical value in the field of kinematic analysis of structural mechanics. Using visualization technology, we reveal how convolutional neural network learns and recognizes structural features. Using pre-trained VGG16 model for feature extraction and fine-tuning, we found that the generalization ability is inferior to the self-built model.
