Bearing Rotation Strain Test (8000 rpm)

High-speed rotating bearings are widely used in aerospace, automotive, industrial machinery, and other fields, enduring enormous centrifugal forces and mechanical stresses during operation. To ensure bearing reliability and service life at high rotational speeds, rigorous strain testing is required. However, because bearing deformation at high speed is extremely small and changes instantaneously, conventional measurement methods struggle to achieve accurate full-field strain capture.

Combining monocular 3D DIC technology with high-speed imaging, the Haytham monocular 3D high-speed visual strain gauge captures the strain distribution of bearings during high-speed rotation with extremely high precision and frame rate. The instrument records minute deformation of the bearing surface in real time and generates high-resolution full-field strain maps, providing key data for strain analysis under high-speed rotation.

In the bearing rotation strain test, the bearing was mounted on a test platform and driven to rotate at 8000 rpm. The Haytham monocular 3D high-speed visual strain gauge monitored the strain state of the bearing surface in real time through the high-speed camera. Under high-speed rotation, the instrument captures the strain distribution of the bearing at different rotational speed stages in a non-contact manner, especially the deformation of stress concentration regions.

The acquired strain data are used to generate full-field strain distribution maps of the bearing under high-speed rotation. From these data, engineers can analyze the centrifugal stress and strain concentration points produced during high-speed operation and identify regions where fatigue damage may occur. The analysis results help optimize bearing design, improve performance and service life under extreme conditions, and reduce the risk of failures caused by material fatigue or structural failure.
