high frequency, a peak not identified before by older equipment. Unless it is of considerable magnitude, or the amplitude increases over time, it usually does not indicate a problem. A report of the sudden appearance of a peak at high frequency may indicate that the vibration tech has a new analyzer, rather than a machinery problem.

vibration mill maximum frequency -

Frequency, when applied to whole body vibration machines, is the number of times the platform completes a cycle of movement per second. More likely than not, this is the maximum potential frequency that the machine can move the platform, in a perfectly controlled environment with no load or friction on the machine!


Accurate vibration measurement requires selection of the best measurement locations on the fan assembly. It also requires choosing the best type of vibration transducer for the particular frequency, or frequency ranges of primary interest. In recent years, piezoelectric accelerometers have become by far the most widely-used transducer type

Vibration Mill Maximum Frequency -

Vibration Mill Maximum Frequency; 12. VIBRATION ISOLATION - (maximum isolation), the excitation frequency should be as high above the natural frequency as possible. The transmissibility above resonance has a slope of –20 dB/decade. The transmissibility above resonance has a slope of –20 dB/decade.

Measuring Vibration (br0094) - Brüel & Kjær

Vibration signals in practice usually consist of very many frequencies occuring simultaneously so that we cannot immediately see just by looking at the amplitude-time pattern, how many components there are, and at what frequencies they occur. These components can be revealed by plotting vibration amplitude against frequency.

Beginning Vibration Analysis -

Frequency Span / Number of Analyzer Lines The frequency span is calculated as the ending frequency minus the starting frequency. The number of analyzer lines depends on the analyzer and how the operator has set it up. Typically, this is the value that can be measured by the cursor Example: 0 to 400 Hz using 800 lines Answer = 400 / 800 = 0.5 Hz ...

X2 Mini Mill Vibrations and Chatter | The Cogwheel

Jun 27, 2016· I remounted my cell phone to the mill and determined the new natural frequency. As you can see the data is becoming more choppy. This is due to the increased frequency and the 100 Hz limitation by my phone. From the graph I found the period of the vibration to be 0.022 seconds with the inverse or frequency to be 45 Hz. That's better!

Which Frequency Is Best For Whole Body Vibration?

Scientists have shown that when the vibration from a Whole Body Vibration platform is set at the same frequency as the natural resonance frequency of a muscle, this is the frequency which will cause maximum muscle activation (3). What Is The Maximum Frequency That Can Be Used For Stimulating Muscle Activity With Whole Body Vibration?


1 VIBRATION DIAGNOSTICS – PRELIMINARY CONSIDERATION S Each machine, if it has to work reliably throughout its planned life, must be maintained.
