I want to apply harmonic load (i.e. vibrating of motor) in harmonic response analysis.
If you have a rotor of mass m and the center of mass is a distance e from the axis of rotation and the rotor is turning with an angular velocity Omega, the amplitude of the rotating force is F = m*e*Omega^2
Machines with high speed rotors are usually balanced to get e = 0 or something very close to zero.
Every force applied in a Harmonic analysis is the amplitude of a harmonic force.
How to calculate the value/Amplitude of the harmonic force ( i.e. in my case Vibration of the mounted motor) ?
Any suggestion regarding this please!
