The application of neural network model in engineering prediction is frequent. The BPE shell material was optimized, and the reliability of the new material was verified by modal simulation. The accuracy of finite element modeling was ensured by constrained mode experiments, and all variables were preprocessed by Latin hypercube sampling. The design parameters were determined by Monte Carlo simulation. Four different neural networks, including back propagation (BP), radial basis function (RBF), extreme learning machine (ELM) and wavelet neural network (WNN), are used to train and learn the dataset. The BPE weight reduction ratio was 14.3%, the stress was reduced by 18.6%, deformation displacement was reduced by 14.2%, and the first-order mode was increased by 29.1%.
神经网络模型在工程预测中的应用十分频繁。对BPE外壳材料进行了优化,并通过模态仿真验证了新材料的可靠性。通过约束模态实验确保了有限元建模的准确性,所有变量均采用拉丁超立方抽样进行预处理。设计参数由蒙特卡罗模拟确定。使用四种不同的神经网络,包括反向传播(BP)、径向基函数(RBF)、极限学习机(ELM)和小波神经网络(WNN)对数据集进行训练和学习。BPE的减重率为14.3%,应力降低了18.6%,变形位移降低了14.2%,一阶模态提高了29.1%。
