We were asked the following question…
I want to perform some cylinder head and inlet manifold vibration analysis, what should I do?
First we need to consider sensor selection Continue reading How do I perform vibration analysis on a cylinder head and inlet manifold?3265class="post-3265 post type-post status-publish format-video hentry category-dats category-tutorial category-video tag-coherence tag-dats tag-frf tag-hammer tag-hammer-testing tag-james-wren tag-modal-analysis tag-modal-testing tag-p8000 tag-prosig tag-time-series-data tag-vibration post_format-post-format-video"
James Wren (Prosig UK) explains how to store FRFs, coherence and/or time series data in modal hammer testing using Prosig’s P8000 & DATS software.

Here we look at how to calibrate an accelerometer using a Prosig P5000 system.
Put the wax on the shaker top. Place the accelerometer in the axis you wish to calibrate with positive up and cable connected to P5000 with the relevant transducer class chosen.
Go to Single Channel Calibration screen.
Click on the Tone tab.
With P5000 armed turn on the shaker and monitor the sine wave on the real-time monitor and check Signal Quality as being GOOD.
With a GOOD sine wave click the Calculate button. It is recommended to click Calculate three times.
Check to see the Sensitivity change from what was originally entered when setting up the channel transducer information to the new calculated value. The calculated value should be close to the original.
DC Cal Offset is for DC level accelerometers.
Requested Excitation is for non IEPE (ICP) accelerometers such as capacitive.
After calculating the new sensitivity click on the Use button to make the change in the Transducer Sensitivity Acquisition Setup file.
NOTE: To achieve a GOOD signal reading place the shaker on a flat surface and avoid touching during operation. Make sure the surface the shaker is sitting on does not come in contact with other sources of vibrations or electrical conductance.3257class="post-3257 post type-post status-publish format-video hentry category-dats category-p8000 category-tutorial category-video tag-data-acquisition-hardware tag-hammer tag-hammer-impact-test tag-hammer-test tag-impact-test tag-modal-analysis tag-modal-analysis-software tag-p8000 tag-prosig tag-structural-testing tag-vibration post_format-post-format-video"

“How do I balance a shaft?” seems like a fairly straightforward question, but there are a number of things that we need to understand first. Here we look at a number of key concepts that need to be understood in order perform balancing.
Well broadly speaking to balance a shaft, mass must be added or removed at certain angles. The concept being that the centre of gravity and rotational centre of the shaft will be equal when the shaft is balanced.

The latest version of the DATS software is now available. Log in to the Prosig support site to download your copy. The new version, V7.0.23, contains many new features, improvements and bug fixes. Read on to find out a little of what you can expect.

After listening to customer feedback, we have completely re-engineered the DATS Hammer Impact software. The new version will ship with the next DATS update (not the soon-to-be-released V7.0.23). In the meantime you will be able to download and preview the new package. You will of course need a P8000 system and a DATS licence with the Hammer Impact option enabled.
