How To Calculate A Resultant Vector
Posted on January 12, 2012 | No CommentsWe can distinguish between quantities which have magnitude only and those which have magnitude and are also associated with a direction in space. The former are called scalars, for example,...
Negative Frequencies – What Are They?
Posted on December 13, 2011 | 1 CommentNormally when we are analysing a signal it is a purely real signal, that is it has no imaginary part. A classic example is of course a sine wave. When...
Vibration : Measure Acceleration, Velocity or Displacement?
Posted on September 5, 2011 | 3 CommentsWhen using vibration data, especially in conjunction with modelling systems, the measured data is often needed as an acceleration, as a velocity and as a displacement. Sometimes different analysis groups...
How To Analyze Noise & Vibration In Rotating Machines
Posted on August 9, 2011 | 3 CommentsIn this article we will look at the basic steps behind a simple rotating machinery study. We won’t look in great detail at some of the techniques involved – we deal with...
Converting Acceleration, Velocity & Displacement
Posted on December 16, 2010 | 9 CommentsFrom time to time I meet engineers who are interested in the conversions between acceleration, velocity and displacement. Often, they have measured acceleration, but are interested in displacement or vice...
Calculating Velocity Or Displacement From Acceleration Time Histories
Posted on October 5, 2007 | 11 CommentsIt is quite straightforward to apply “classical” integration techniques to calculate either a velocity time history from an acceleration time history or the corresponding displacement time history from a velocity...
Acceleration, Velocity & Displacement Spectra – Omega Arithmetic
Posted on December 7, 2006 | 18 CommentsAccelerometers are robust, simple to use and readily available transducers. Measuring velocity and displacement directly is not simple. In a laboratory test rig we could use one of the modern...
