Forced harmonic vibration

WebOct 30, 2024 · The total solution to the forced vibration equation of motion (Eq. 3.1) has two parts: (1) the homogeneous, or transient , solution; and (2) the particular, or steady-state , solution. The transient portion is the free vibration response, m\ddot {x}+c\dot {x}+ kx=0 , and, as we saw in Chap. 2, it rapidly decays for damped systems. WebThe calculation of the response of rotationally periodic structures to transient forces and prescribed motions is considered. The work extends the work previously described by Thomas 1 in which only the free and harmonic forced vibration problems were considered. It is assumed that the finite element method is to be used, so that the equation of motion …
