颤振频率 meaning in English

flutter frequency
flutter oscillation frequency

To a series of dampings , velocities and frequencies , the linear interpolation is applied and the flutter speed and flutter frequency are obtained
对得到的一系列的阻尼、速度和频率进行了线性插值，从而得到颤振速度和颤振频率。
To tackle this problem , a novel methodology is proposed to suppress the vibration of the spindle by means of chatter frequency identification and on - line regulation of spindle speed
为此,本文采用辨识颤振频率和主轴转速在线调节的方法,与磁轴承控制相结合抑制主轴振动,取得良好效果。
