Fig. 1. Strip faults, due to rolling mill vibration The integrated control process is made to analyse the vibrations which are produced on the work roll chocks and backup roll chocks. The noise and chatter signals are carried out in the time and frequency range. The noise has to be eliminated to obtain reliable strip quality in conformity with predicted dimensions. On the long term we can ...

The transmissibility as a function of frequency ratio is shown in Figure 3. Vibration isolation (defined as T<1) occurs when the excitation frequency is > 1.4 f n. For minimum transmissibility (maximum isolation), the excitation frequency should be as high above the natural frequency as possible. The transmissibility above resonance has a slope ...

Frequenzen über 33 Hz machen für den Muskelaufbau keinen Sinn, denn der Muskel schafft eine saubere Kontraktion in maximal ca. 27 Hz [14]. Anfänger arbeiten am besten mit Frequenzen von 25 Hz bis zu maximal 30 Hz, wie z.B. bei dieser Grundübung: ein Fuß auf die Platte stellen und mit beiden Armen die Haltestange umgreifen, oder bei der Übung Kniebeuge.

Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point.The word comes from Latin vibrationem ("shaking, brandishing"). The oscillations may be periodic, such as the motion of a pendulum—or random, such as the movement of a tire on a gravel road.. Vibration can be desirable: for example, the motion of a tuning fork, the reed in a woodwind instrument or ...

At any given speed below 36 rpm (80% critical), the intensity of vibration increases as the ball load decreases, i.e., the mill loaded with 140 kg ball load (45% filling) gives the maximum amplitude of vibration. This happens because up to 36 rpm, the effective circulating distance (the distance from the cascading surface and back) moved by the whole charge mass decreases as the mill filling ...

Most people are sensitive to the frequency of vibration in the range of 8 Hz to 10 Hz; because some human organs have the frequency ranges from 4 Hz to 8 Hz (Wilson, 1998). If the structures have the frequency bellow 10 Hz, then it creates resonance with human body. This resonance may cause undesirable vibration to the people (Murray, 1997). 1, 2, 3 Undergraduate Student . 4 Professor . .

Special equipment drivers often suffered from vibration which threatened their physical and mental health. In order to study the riding comfort of a special equipment cab, a hammering experiment has been carried out on it by acceleration sensors. According to the test results, the natural frequency has been calculated which was compared with the result analysis by the finite element method.
