Experimental Verification of Effect of Different Fluid Properties on the Vibration Response of a Cantilever Rotor

  • Published:
International Applied Mechanics Aims and scope

The current analysis is an effort to obtain the vibration characteristics of a cantilever rotor shaft with an extra mass added at the free end of the rotor shaft partially immersed in a viscous medium. This work is concentrated on the theoretical analysis of the natural frequency and amplitude of the spinning cantilever rotor shaft with addition mass using the influence coefficient method. The influence of fluid forces is studied using the Navier–Stokes equation. The gap ratio (ratio of the fluid-filled container radius to the shaft radius) and viscosity of the fluid are taken as the main variable parameters.MATLAB programming is used to obtain vibration behavior from the theoretical expressions. The obtained result from the numerical analysis is validated by the comparison of the results of experimental analysis.
