Technical Issues for Electrodynamic Shakers: When to select optional welded magnesium Drive Adapter
The question of “when do we have to choose the optional welded magnesium Drive Adapter” has come, so we wanted to take this opportunity to explain the typical rule of Continue Reading →
Dynamic Signal Processing Review Part 2 – The Frequency Domain
To effectively understand dynamic signal analyzers and vibration controllers, this article aims to describe basic dynamic signal analysis concepts. Many dynamic data processing techniques involve transforming the data to the Continue Reading →
How can Coherence be measured when the excitation is Sinusoidal?
Coherence is the measure of how much of a response is due to the (known) excitation. This is easily measured when the excitation is broadband and it is possible to Continue Reading →
Dynamic Signal Processing Review: Part 1 – Digitizing and Dynamic Range
The fundamentals of signal processing are important for users of test instrumentation. To understand dynamic range, it helps to start with the basics of digitizing data. As an analog signal Continue Reading →
Modal Testing with Shaker Excitation
Modal analysis is the study of dynamic characteristics of a structure under test. The purpose is to identify the Modal parameters of the structure under test. Modes are inherent properties Continue Reading →
The Importance of Dynamic Range in Vibration Control
Discussions about dynamic range are most often concerning dynamic signal analyzers. However, a large dynamic range is perhaps even more beneficial for closed loop vibration control. In vibration control applications, Continue Reading →
