We provide specialized support in the testing, analysis, and fatigue evaluation of vibrating blades used in high-speed rotating machinery such as turbines, compressors, and fans. Blade vibration is a critical consideration in the design and life management of aero-engine and industrial turbomachinery components, and our expertise covers the full spectrum from test definition through to life prediction.

Our Capabilities Include:

• Test Definition and Planning
  We work with OEMs and test houses to define meaningful and cost-effective vibration test plans, including frequency ranges, boundary conditions, excitation methods, and instrumentation strategies.

• Biaxial Vibration Testing
  We support and interpret biaxial (2D) testing, which more closely replicates in-service dynamic response and excitation modes, particularly for highly loaded or tuned blade rows.

• Data Post-Processing and Interpretation
  We extract and interpret strain gauge or displacement sensor data from test campaigns, including filtering, cycle counting, and frequency-domain analysis.

• Fatigue Lifing and Curve Development
  Using test results and validated material models, we generate stress–life (S–N) or strain–life (ε–N) curves to assess component durability under various vibratory load cases and environmental conditions.

We apply our understanding of blade dynamics, fatigue behavior, and material response to help clients ensure component reliability, extend service life, and meet safety-critical certification standards.
