Difference between Vertical and Horizontal shaft rotordynamics

  1. Jul 1, 2011 #1
    Hello all,

    I am new to physics forums so please excuse my posting mistakes (if any).

    I wanted to know how different is the rotordynamics when one is analysing a vertical machine v/s a horizontal machine ? Is it substantial or we can analyse it as a horizontal machine and extend the results to the vertical machine ?

    This question came to my mind since in a horizontal machine your center of gravity is acting uniformly across the entire length while in a vertical machine your center of gravity is just acting in the vertical downward direction (there might be a moment acting in this case when the shaft undergoes different modes).

    Thank you,
