When using the Machinery Vibration Severity Chart, thefollowing factors must be taken into consideration: 1. When using displacement measurements only filtered displacement readings (for a specific frequency) should be applied to the chart. Unfiltered or overall velocity readings can be applied since th...

Based on the frequency patterns, a frequency characteristics chart has been developed and is presented in the paper; it provides good trial frequency values for use in the Holzer technique for the determination of the intermediate frequencies. A non-dimensional parameter termed as the "nature ...
Tandon and Nakra [1] presented a detailed review of the different vibration and acoustic methods, such as vibration measurements in time and frequency domains, sound measurements, the shock pulse method and the acoustic emission technique, for condition monitoring of rolling bearings. Some of the ...
Accelerometers typically have a more extended high-frequency capability than piezovelocity sensors, whereas the moving coil sensors have a very limited linear range. Accelerometer: highest frequency response. Used for gear mesh, impulse, and other high-frequency applications. Piezovelocity sensor: lower ...
From analyses of the frequency-volume chart, mean and maximum volume/void were significantly increased (P < 0.05 each).Lower urinary tract symptoms detected in patients >or=1 year after radical prostatectomy were markedly improved with administration of naftopidil at 75 mg/day. These symptoms ...
9 noted that the frequency of blast-induced vibration plays a crucial role in destroying structures near a mine. The impact of blast-induced vibrations on surrounding structures, sensitive equipment, and people in urban environments is a crucial aspect of a sustainable mining project. Variables such...

The basic idea of present approach is to design a linear vibration isolation system with very small damping first, and then an elastic stop with large damping. In the working frequency range, the slightly damped vibration isolation system has required vibration transmissibility. Once the vibration is...
