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. Where m k ω WebApr 10, 2024 · The power oscillation induced by pressure fluctuation in the draft tube of the hydraulic turbine is one of the limiting factors preventing the Francis turbine from operating in the vibration zone.
