We are proud to announce the publication of our latest scientific article in the prestigious IEEE Transactions on Instrumentation and Measurement:
Title: Aero-Engine Compressor Bladed Disk Vibration Measurement Using Blade Tip Timing and Laser Doppler Vibrometry
DOI: 10.1109/TIM.2024.3404472
🔍 What’s the Study About?
The paper presents a hybrid methodology that combines Blade Tip Timing (BTT) and Laser Doppler Vibrometry (LDV) to measure the vibration of compressor bladed disks in aero-engines.
BTT is a non-intrusive technique that uses sensors to record the precise time each blade passes by. LDV, on the other hand, uses laser technology to measure vibrational velocity. By synchronizing data from both systems, we enhance the accuracy of vibration measurement and gain insight into both synchronous and asynchronous blade dynamics.
💡 Key Contributions
- ⚙️ A dual-method framework that leverages both BTT and LDV in real aero-engine conditions
- 📊 Validation of BTT signals using high-precision LDV data
- 🧮 Modal reconstruction of bladed disk vibrations with high temporal resolution
- 📈 Comparison between experimental and simulated vibration modes
🚀 Why This Matters
Understanding blade vibration is critical for preventing fatigue failure, increasing engine lifespan, and improving maintenance prediction. Our method provides researchers and engineers with a reliable way to detect and analyze blade dynamics without invasive instrumentation.
