| Abstract: | A non-uniform beam is modeled to a system with a multi-degree of freedom by discretization.The vibration frequency of the system is studied to avoid resonance for safety purpose by adjusting the frequency of an extemal dynamic load or beam stiffness to separate the excitation frequency from self-vibration frequency. |

| Keywords: | non-uniform beam frequency self-vibration frequency |
