amplitude at resonance 中文意思是什麼
amplitude at resonance
解釋
諧振幅值-
Damping wakes possible finite steady-state vibration amplitude at resonance.
在共振時,阻尼可能限制穩定振動的振幅。 -
Analysis software. the analysis show : the gyroscope effect to the flywheel rotor ' s and the shaft ' s vibration character under high rotate speed should be considered. at this time, the system ' s normal frequency is the function of rotate speed ; the amplitude passing through the resonance field can be lowered obviously by improving the effective damping of the electro - magnetic bearing
建立了高速旋轉狀態下,採用磁軸承作支撐的飛輪轉子和轉軸的動力學模型,給出了有限元法在此問題中的具體應用,並利用i - deas有限元分析軟體具體分析了飛輪系統的共振頻率、系統振型,以及對偏心激勵的響應,分析表明:對于高速旋轉的飛輪轉子和轉軸,應考慮陀螺效應對其動力學特性的影響,此時系統的固有頻率是轉速的函數;通過提高磁軸承的等效阻尼可顯著降低系統通過共振區域時的振幅。
