面向智能建造的模块化全装配穿索式脊杆索穹顶体系数字孪生及性能反演预测
Digital twin modeling and performance inversion of modular fully assembled cable-strut cable dome system for intelligent construction
摘要
Abstract
A digital twin modeling method considering manufacturing-assembly error coupling was proposed for the modular fully assembled cable-penetrating ridge cable dome system,covering geometric and mechanical twins.Geometric twin was achieved by extracting the structure's configuration via point cloud data;mechanical twin was built through multi-source data fusion and regularization inversion(incorporating geometric defects and joint errors)combined with ANSYS APDL for digital modeling and response inversion.A 100 m span dome and its 1∶10 scaled model were designed.Tests under design,basic and ultimate load combinations show the twin model improves joint displacement inversion accuracy by 9.64%and diagonal cable force accuracy by 12.82%compared with the design model.The safety factor drops from 5.27 to 5.03(4.6%)due to errors;instability stems from rupture of the second and third annular cables,causing abrupt diagonal cable force drops.This study validates the superiority of the method in the inversion accuracy of structural key performance indicators,and lays a theoretical foundation for the error control and safe operation assessment of the cable domes.关键词
