Derive the equation of motion, using Newton’s laws (or sometimes you can use energy methods, as discussed in Section 5.3) 2. Do some algebra to arrange the equation of motion into a standard form. 3. Look up the solution to this standard form in a table of solutions to vibration problems. WebUndamped Free Vibration (γ = 0, F(t) = 0) The simplest mechanical vibration equation occurs when γ = 0, F(t) = 0. This is the undamped free vibration. The motion equation is m u ″ + k u = 0. The characteristic equation is m r 2 + k = 0. Its solutions are i m k r=±. The general solution is then u(t) = C 1cos ω 0 t + C 2sin ω 0 t.
