Bearings and gearbox vibration are fundamental issues for rotating machines in many industrial applications. These are critical components and, as such, any failure can prove expensive in both

This is often also known as Modal Testing. It is a method of testing that allows us to calculate the natural frequencies (modes), modal masses, modal damping ratios and

This is an important subject to understand when working in the signal processing field. In terms of AC and DC Coupling, what is Coupling? Quite simply, coupling is

When 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

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

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

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
