Abstract


This paper studies the harmonic response analysis in steam turbine parts, gear box, induced draft fan part of induced draft fan shaft system based on the theory of simple harmonic excitation by using ANSYS software platform. It mainly studies the response characteristics near the low order natural vibration frequency. It investigates the response of each key position in the condition of the coupling system, and adopts harmonic response analysis (ANSYS software) to gain steady-state response of each point on the shaft system.

Keywords


Harmonic response analysis, induced draft fan, ANSYS software platform, steady-state response.
