| Abstract: | The differental equation of gate vibration was established by nonliner resonant oscillator. The parameters in the equation were determined by model experiment. A semi-theoretical solution was obtained. The results indicate that the mathematical model can accordingly represent the intrinsic mechanism of the self-excited Vibration. It is useful for determing the characteristics of plate gate vibration of an engineering. |
