SimuTech provides a blade frequency testing service for new, refurbished or reverse engineered turbine blades (buckets) to ensure that their natural frequencies are within specifications. This is especially critical for longer tuned last stage steam turbine blades that are susceptible to high-cycle fatigue failure due to resonance during operation.
SimuTech performs on-site testing of blades and blade groups on rotors.
Our blade frequency testing proves valuable for quality assurance of industrial gas turbine (combustion turbine) blades.
Excitation techniques include:
Response measurement techniques include:
SimuTech also has extensive experience with vibration test fixture design.
