| Abstract: | The basic structure and theory of Pohl resonator were introduced.Phase-frequency and amplitude-frequency characteristics were measured,and found that when the resonance of the system appeared,drive-frequency is almost equal to inherency-frequency,and phasic angle margin is equal to 90°.Finally,system error was analyzed. |

| Keywords: | forced vibration Pohl resonator phase-frequency characteristics amplitude-frequency characteristics |
