Industrial Structural Load and Strain Testing

An industrial structural load and strain testing workflow for coefficient calculation, staged loading, and load-sharing verification.

Project Type

Industrial Equipment Monitoring

System Scale

adjustable structural member coefficient testing using 10 ton, 15 ton, and 20 ton loads, followed by staged 300-600 ton load verification in 50 ton steps

Data Output

rod strain, strain coefficient, virtual channel load, rod load distribution, staged lifting trend

Engineering Value

How the system supported engineering decisions

The case converts structural load and strain testing into a public DL-DAQ and DL-SHM verification workflow.

Strain coefficient calibration gave the lifting team traceable evidence before 300-600 ton operation.

Virtual channel load calculation and rod-to-rod comparison supported safer heavy lifting execution.

Monitoring Content

Monitoring scope and field constraints addressed by the deployment

Rod coefficients had to be calibrated accurately from strain data before heavy lifting could proceed.

Sixteen rods required load balance tracking during staged 300-600 ton simulated lifting.

The system needed virtual channel calculation and strain coefficient review without exposing internal software or hardware codes.

Project Overview

Engineering context and monitoring scope

A Sanmen energy facility required calibration testing for adjustable rods to obtain rod coefficients. Strain gauges were bonded at the rod center, crane loads of 10 tons, 15 tons, and 20 tons were applied, and coefficients were calculated from three datasets with errors within 0.5%. A subsequent lifting test used the coefficients to calculate lifted weight through software virtual channels. Sixteen rods were loaded from 300 tons to 600 tons in 50 ton increments, and rod-to-rod load difference was adjusted from a required limit of 20% to within 10% before lifting.
