AI Technical Summary

Technical Problem

Existing fatigue load testing devices and methods cannot effectively simulate the fatigue load under complex loads under actual service conditions of specimens. Existing devices and methods cannot fully characterize the multiaxial fatigue state of fatigue-prone parts of real bridges, and data acquisition devices cannot achieve effective and real-time coverage of key monitoring areas, thus failing to meet the fatigue strength design and life assessment requirements of complex structural systems.

Method used

A corrosion fatigue combined damage testing device and method are provided, including a support unit, a vertical testing unit, a transverse rotation testing unit, a corrosion testing unit, and a monitoring unit. These units simulate the complex loads of the specimen under actual service conditions, and the monitoring unit records and analyzes the specimen in real time. The device and method enable corrosion testing and performance evaluation of the specimen by real-time monitoring and analysis of the specimen.

Benefits of technology

It enables the simulation and real-time monitoring of corrosion-fatigue combined damage of specimens, providing basic data for the fatigue damage mechanism of easily damaged parts of steel bridges under complex environmental loads. It has a wide range of applications, can simulate the actual service conditions of specimens, and provide high-precision test data and analysis results.
