基于代理模型的输电塔半刚性节点弯矩-转角曲线预测方法
A surrogate model-based prediction method of moment-rotation curve of semi-rigid joints in transmission towers
摘要
Abstract
In order to accurately and efficiently evaluate the mechanical properties of semi-rigid joints in transmission towers,a method based on surrogate model is proposed to predict the moment-rotation relationship of the semi-rigid joints.By introducing the surrogate model method to approximate the functional relationship between the geometric dimensions,ultimate flexural capacity,and initial rotational stiffness of semi-rigid joints,a prediction model with high accuracy is established.Furthermore,the moment-rotation curves of semi-rigid joints in transmission towers are fitted using the Kish-Chen power function model.The results show that the proposed surrogate model-based prediction method for moment-rotation curves of semi-rigid joints can reduce the cost of experiments and numerical simulations,while accruately approximating the actual force-deformation relationship of semi-rigid joints in transmission towers.This method also provides valuable insights for the engineering design and theoretical research of semi-rigid joints in transmission towers.关键词
