When we are dealing with multiple measurements we often need to calculate a resultant vector to understand their combined effect. What do we mean by this? And how

In this article we will look at the basic steps needed to measure noise & vibration in rotating machines. We won’t look in great detail at some of

Here is a great little collection of engineering animations from the simple everyday to the more sophisticated. A brilliant way to learn how things work. We hope you like them.

From 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

Here’s another post inspired by an office discussion. We were discussing our favourite engineering based websites and realised the results would make a great blog post. So after

The following article will attempt to explain the basic theory of the frequency response function. This basic theory will then be used to calculate the frequency response function

Most engineers are probably familiar with or have come across the decibel or dB as a unit of measurement. Its most common use is in the field of

It 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

We hear the word used a lot, but what is resonance? First, in order to explain we have to explain the terms we will use. A period is

To illustrate the use of the cross correlation function, a source location example is shown below. For this, it is assumed that there is a noise source at
