Research on Calculation Method for Dynamic Stress of Steam Turbine Blades Based on Harmonic Response Analysis
Having the harmonic response module in finite element calculation software adopted to analyze the steady state response of turbine straight blade under different harmonic excitations was implemented to obtain its dynamic stress at resonance frequency,including the stress situation under the rated operating conditions.In addition,through comparing the dynamic stress and their static bending stress of steam tur-bine straight blades,the distribution law of dynamic to static ratio was obtained to provide an idea for de-signing turbine straight blades
