Specialized Testing for Turbine Blades
Turbine blades are intended to withstand high static and dynamic stresses. Static stresses can be measured or computed with resembling accuracy, but dynamic stresses are evaluated more precisely through experimental rather than theoretical designs.
Consequently, blade frequency testing requires specialized approaches by engineers well-disciplined in the field. SimuTech Group performs laboratory & on-site testing of blades and blade groups on rotors and has extensive experience with vibration test fixture design.
As for structural requirements, ensuring natural frequencies are within specifications is especially critical for longer tuned last stage steam turbine blades that are susceptible to high-cycle fatigue failure due to resonance during operation.
To ensure accuracy under various settings and conditions, SimuTech Group measures blade frequencies with distinct boundary conditions including “free-free”, fixtured, installed on a rotor, and during operation.
