[An Introduction To Vibration Analysis - Part 1] Introduction For professionals delving into the worlds of automotive, aerospace, or industrial engineering, vibrations are not just mere oscillations; they're a symphony…
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 analysis groups require the measured signals in a different form. Clearly, it is impractical to measure all three at once even if we could. Physically it is nigh on impossible to put three different types of transducer in the same place.
This piece on Claude Shannon is the first in what will become a series of posts looking at the key figures who shaped the thoughts, theories, algorithms and technologies that…
An Impact Hammer double hit is viewed as a common problem, and most hammer impact testing software offers a "Double hit" rejection function. Signals captured with double impacts are not…
Understanding CAN bus (Controller Area Network Bus) is essential to modern automotive engineering. The CAN bus, and its variants, are now universal across the automotive industry and beyond. On many…
Electric vehicle noise & vibration testing is crucial for vehicle development, ensuring the final product’s comfort, safety, and reliability. While electric vehicles (EVs) and internal combustion engine (ICE) vehicles undergo…
Welcome to our latest blog post, where we delve into the fascinating world of resonance and natural frequency! Over the years, we've consistently noticed that our articles exploring these topics…
A Hammer Impact Test is also known as a Modal Test, Impulse Test, Tap Test, Bump Test or, simply, a Hammer Test. It is a method of testing that allows…
Tools for motorcycle dynamics analysis - Prosig DATS and Structural Animation Viewer Mechanical engineering covers a vast field of topics, but not many fields feature higher dynamics in time and…
This article discusses quantifying basic vibration signals from three aspects: signal type, signal level, and signal display format. Mathematical expressions and typical applications are also introduced. A simple harmonic vibration…
This post deals with automated data capture and analysis of data. It uses Prosig's DATS software and the worksheet environment it provides. The technique could be duplicated in other software…

The difference between Low noise and Non-Low noise accelerometer cables. It is important to use the correct cable when using accelerometers. A charge output accelerometer must be used with a…
When performing experimental modal testing of a structure or component using impact (or ping) testing, it is important to consider and verify the validity of any results. A modal analysis…
Mass loading is the phenomenon whereby the mass of the Accelerometer alters the natural frequency of the test subject The video below demonstrates the phenomenon of mass loading and the…
Condition Monitoring Group Ltd (CMG) are pleased to announce the acquisition of DJB Instruments Ltd based in Mildenhall near Cambridge in the UK. DJB will join Prosig, Helitune, Beran Instruments,…
A vital question to be asked before performing hammer testing is - how do I support the testing object? What fixing mechanism to use? Or technically, what are the desired…
The identification of cyclic events in rotational analysis is often key to identifying problems. It is good practice to use a suitable sensor for capturing rotational speed. However, this is…
The analysis of dynamic engine vibration and the accurate measurement of angular vibration is a non-trivial task, as a more in-depth analysis of boundary conditions reveals. Tools for engine vibration…
