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 also performs on-site testing of blades and blade groups on rotors. Our blade frequency testing also proves valuable for quality assurance of industrial gas turbine (combustion turbine) blades.

Excitation techniques include modal hammers, shakers, piezoelectric actuators, and acoustic horns. Response measurement techniques include accelerometers, laser vibrometer, and microphones.

SimuTech also has extensive experience with vibration test fixture design.
