Surrogate Model for Predicting Structural Performance of Gears Based on Spatio-Temporal Graph Neural Networks

工程科学与技术
齿轮啮合动态仿真涉及大规模非结构化有限元网格和长时序非线性数据，代理模型可以替代原始数值分析模型实现快速计算。然而，传统代理模型难以在非结构化网格上捕捉物理场的空间相关性，且对各时间步独立建模，无法反映啮合过程的长时序依赖与非线性演化。为此，本文提出了一种融合图卷积网络（Graph Convolutional Network， GCN）与时序卷积网络（Temporal Convolutional Network， TCN）的时空图神经网络（Spatio-Temporal Graph Neural ...

T形钢管混凝土柱-H形钢梁侧接板式节点承载力研究

Jianzhu Gangjiegou Jinzhan
为研究T形钢管混凝土柱-H形钢梁侧接板式节点的受力机理，对该节点进行了有限元模拟和理论分析研究。首先建立Abaqus有限元数值模型，通过试验结果验证了数值模型的合理性；根据节点构造特点，推导了该节点的受弯承载力和受剪承载力计算公式，并采用数值模型算例进行验证；基于计算公式分析不同变量对节点受弯承载力和受剪承载力的影响。研究结果表明：给出的有限元模型能够有效模拟侧接板式节点的工作状态和极限承载力；侧接板式节点的受弯破坏有4种破坏形态，通过合理构造可以确保首先出现钢梁翼缘受拉屈服破坏，实现节点的延性破坏 ...
