Read Response Of Damped System Under Harmonic Force - Updated

Check response of damped system under harmonic force. Mx cx kx F t For a harmonic force we select F t F o cos t. Damped vibrating system the characteristic is given by. Two versions of the procedure are in use. Check also: damped and response of damped system under harmonic force Vibration excitation due to imbalance in rotating machines is discussed.

F o the magnitude of the force the forcing frequency The EOM becomes cos o mx cx kx F t A Homogeneous Solution x h t where n is the un-damped natural frequency of the system and n k m. 16Response under a general periodic force If the forcing function is periodic we can use the Fourier series and the principle of superposition to get the response.
