New Customer Laboratory System Launched in Everett, Washington
Exciting event this week. Kevin McIntosh, General Manager of the Vibration Test Systems Business Unit attended the opening of our customer’s new Engineering and Prototype Laboratory in Everett, Washington. The Continue Reading →
Evaluating Controller Performance – Part 1 – Swept Sine
This is part one in a series of articles about how to evaluate the quality of a vibration control system. In each we will present important features of the control Continue Reading →
Seismic Testing Using SignalStar Controllers
With the tragic earthquake and resulting tsunami in Japan last year, there is an increased focus on ensuring that critical equipment can withstand earthquake forces. The Data Physics SignalStar Vector Continue Reading →
Multishaker Vibration Testing
Multishaker testing has been growing in popularity over the past several years. This testing is done not only in the automotive industry, but across the board in the Aerospace, Defense, Continue Reading →
Understanding Shock Response Spectra
Shock Response Spectra (SRS) are now widely used in many industries. Data Physics analyzers and controllers make the process of measuring Shock Response Spectra and producing transients from a given 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 →
Frequency Resolution in Random Vibration Control
Data Physics was the first to market very high resolution random control – 6400 lines of resolution. The use of narrowly spaced spectral lines in random control has both positive Continue Reading →
Benefits of Dual Shaker Single Axis Testing
The demand for very large force shaker systems is increasing. Typically this is met with large electrodynamic shakers (approximately 45klbf to 60klbf). However, larger shakers have limited frequency range. Shakers 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 →
Cross Axial Stiffness and Moment Restraint
In the recent past, we have been asked by several customers, distributors, and employees, why the cross axial stiffness numbers for SignalForce shakers appear to be smaller than the numbers Continue Reading →
Durability Testing of Crankshafts
The Data Physics SignalStar Vector control system is commonly used in the automotive industry for durability testing of engine crankshafts. The crankshaft is an engine component that converts the reciprocating Continue Reading →
Voice Recording and Playback Feature
Voice Recording, available in Data Physics’ SignalCalc Dynamic Signal Analyzer and SignalStar Vibration Controller software as part of throughput to disk analysis, allows the user to utilize an input channel Continue Reading →
