Vibration and Vibration Dampers in Transmission .

This vibration of Transmission Line in vertical plane can be categorized into two groups. 1) Aeoline Vibration. 2) Galloping or Dancing of Conductors. Aeoline Vibration is of high frequency and low amplitude. The frequency of vibration is of the order of 5 to 40 cycle/second while the amplitude being of the order of 2 cm to 5 cm with a loop length of 1 m to 10 m. This type of vibration occurs ...

Transmission of Vertical Whole Body Vibration .Deze pagina vertalen

Transmission of vertical vibration to the ankle, knee, hip and spine over the studied vibration frequency and amplitude ranges are shown in Figs. 3–6. Substantial amplification of peak acceleration could occur between 10 and 40 Hz for the ankle, 10 and 25 Hz for the knee, 10 and 20 Hz for the hip, and at 10 Hz for the spine.

Fundamentals of Vibration Measurement and Analysis Explained

VIBRATION waveform as shown in the time drawing on the left side. This is the summation of all the vibration present at that location. Spectrum analysis enables us to untangle this complex waveform and make a representation of its original components on a diagram showing frequency on the X-axis and amplitude vertically. This is known as a VIBRATION SPECTRUM and is extremely valuable for fault ...

What Causes Transmission Vibration? | It Still Runs

If you find your transmission and car start to vibrate during travel on uneven or bumpy roads, this is because your shocks no longer operate at peak efficiency. A bad steering stabilizer can cause similar symptoms. This can cause the transmission and the entire car to vibrate during times of extended use.

AOLIAN VIBRATION OF TRANSMISSION LINES | .

Aolian Vibrations, also called Karman Vibration is the result of wind forces acting transversely on the conductor which causes alternating excitations in the vertical direction. Aeolian vibrations occur almost on any transmission line, for low to moderate steady winds. They are characterised by small amplitudes of vibration (one conductor diameter) with frequency between 5 and 100 Hz ...
