Quantifying the Vibration Level. The vibration amplitude, which is the characteristic that describes the severity of the vibration, can be quantified in several ways. On the diagram, the relationship between the peaktopeak level, the peak level, the average level, and the RMS level of a sinewave is shown. The peaktopeak value is valuable in that it indies the maximum .

· Vibration Amplitude. The maximum amplitude or range of the vibration you are measuring determines the sensor range that you can use. If you attempt to measure vibration outside a sensor's range, it distorts or clips the response. Typically, accelerometers used to monitor high vibration levels have a lower sensitivity and lower mass. Sensitivity. Sensitivity is .

· How to determine Vibration Amplitude Thread starter Su Solberg; Start date Feb 3, 2010; Feb 3, 2010 #1 Su Solberg. 75 0. Hello Every one, When I am looking at the design of a vibration screen, I found that the claims from different source have different equation. Please have a look on the attachment. You can see "Claim 2 " is a more general approach but need to know spring constant k. .

· The vibration spectrum may show high amplitude at 1X RPM and may have pole passing frequency side bands. These problems occur when the motor is partially loaded. If the stator and rotor slot teeth are not equidistant, there will be reluctance variations in magnetic forces, causing motor torque variations. Torque pulses may excite loose or broken rotor bars .

Vibration lifts and segregates particles on the inclined screen. When vibration amplitude is within the range of 3 to, the equipment segregates the large and small particles with best efficiency. If the amplitude is too high, the contact area between particles and screen surface is reduced and energy is wasted; if too low, particles block the aperture, causing poor .

· One of the most important things to check on a periodic basis is the shape of the screen's vibratory motion. In Figure 1, one can see and verify the shape of the vibratory motion: circular (A), elliptical (B) or even linear (C). It is also possible to assess the amplitude of motion, as provided in Figure 2. Let's examine a few concepts ...

If the vibration spectrum of a machine shows a high amplitude of the FT, it does not mean the bearing has a bad cage, but rather means that one of the rollers is cracked or otherwise deformed. This causes a vibration component to occur each time the roller enters the load zone of the bearing, which is at each revolution of the cage, giving rise to a vibration at that rate. .

In the analysis of the vibration behaviour, both the type (circular, elliptical or linear) as well as its amplitude and the resulting Gforce are in the foreground with the speed and direction of rotation. These factors determine the transport speed, the contact frequency and material distribution on the respective screen decks and the quality of the end product. In the ideal case, the speed ...
