Reduction of the vibration amplitude with variable excitation frequency

In many dynamic systems large vibration amplitudes occur if the operation frequency is near resonance frequency. Also during passage result. order to reduce amplitude of oscillation a suitable excitation can be applied. The force driven single degree freedom harmonic oscillator used analyse reaction system variable analysis starts with mathematical transformation signal in identify influence different parameters. It shown that for specific parameters natural eliminated from signal. both cases, and through resonance, numerical values, correlations between functions found resulting system.
