Rotating Force and Torque Measurement for Aerospace Testing
Project name: Rotating Force and Torque Measurement for Aerospace Testing
Nanjing University of Aeronautics and Astronautics (NUAA) has successfully implemented Dynatronic's RU-846 Rugged Data Recorder for advanced rotating structure testing applications. This system provides precise and reliable measurement capabilities for high-speed rotating components in aerospace, wind energy, and automotive research.
Embedded Measurement in Rotating Bodies
The RU-846 is designed to be installed directly within confined spaces of rotating test specimens, ensuring accurate in-situ data acquisition. Its compact form factor (150×100×50mm) and lightweight design (<800g) allow secure integration without significantly affecting the dynamics of the rotor or shaft. Specialized mounting fixtures provide stability during high-speed rotation, withstanding centrifugal forces while maintaining sensor alignment.
Comprehensive Force and Torque Monitoring
The system enables simultaneous measurement of structural dynamic forces (3-axis, ±5000N range), axial torque (0–2000Nm range), and bending moments. With 16-channel synchronous acquisition at up to 100kHz sampling rate and 24-bit high-resolution recording, researchers can capture detailed dynamic responses across all relevant axes and rotational speeds.
Advanced Data Acquisition and Analysis
The RU-846 includes onboard storage of up to 512GB, supporting continuous recording for 72+ hours. Post-test data can be quickly retrieved via high-speed USB 3.0 interface. Proprietary analysis software allows correlation of strain and torque data, fatigue life prediction, and structural optimization modeling. The system also integrates seamlessly with digital twin models, supporting simulation validation and predictive maintenance strategies.
