Abstract

To ensure the accuracy of the main cable alignment during adaptive rotation,an adaptive spatial rotating main cable saddle suitable for spatial suspension bridges was designed.The main cable saddle had two adaptive rotating pair mechanisms with axes passing through the IP point.By using a specific suspension bridge as a case study,the design was validated through a combination of finite element analysis and model testing to assess the reliability and structural safety of the adaptive rotation mechanism.The results show that the adaptive spatial rotating main cable saddle can automatically adjust its orientation based on variations in the main cable load during construction,with self-limiting rotation to ensure safe and controlled movement.The finite element stress analysis results of the fixed main cable saddle are consistent with the measured stress values of the rotating main cable saddle,indicating that the adaptive rotation balances the lateral force generated by the main cable rotation on the saddle.This leads to an improved load distribution on the spatial main cable saddle,ensuring the reliability of the rotation mechanism,and the structure meets the strength requirement.
