NVGate V12 – What’s new?

Properties are a great feature of the Teamwork platform which allow users to associate contextual information to their measurement data and setups (properties are applied when saving a project, a setup or a measurement). Without such a tool, the natural tendency would be to insert this information in the titles of the measurements making the users life difficult when it is time to sort and find relevant data. New key features are now available in the Properties Manager of NVGate 12.10 which allow a smooth experience of the Dataset Management.

After recording a signal and computing some results with the NVGate plug-ins (FFT, SOA, OCT) you may need to post-analyze the recorded signal to change a few analysis settings or compute additional results using the same plug-ins. With NVGate 12.10, it is now possible to post-analyze a signal by directly using the same setup as the one used during the recording. If required, modifications to the setup can be completed in an additional step.

In a complex environment, it’s not always possible to setup a tachometer. However, analyzing a dynamic signal with RPMs as the reference is always efficient. Therefore, the goal of the Tachtool tool is to extract a tacho signal from dynamic sensors such as accelerometers or microphones. In this example, we have a waterfall of acceleration spectrums with time as our reference. At the end, we obtain a waterfall containing acceleration spectrums with RPM as our reference. This tool simplifies analysis of orders and resonant frequencies.

Thanks to sequences, macros and automatic reports, NVGate is flexible and can be fully automated for measurement campaigns. In the same way, the additional batch post-processing tool allows users to automate their post analysis campaigns. Users will be able to calculate a set of results for an entire measurement campaign. In the example below, we carried out 8 run-ups and 8 run-downs for each, then calculated FFTs, RMS values and overall profiles.

Erroneous data and direction on an FRF node are common issues when completing ODS or modal analysis by analyzing FRFs. With NVGate V12.00, it is now possible to edit and correct the nodes and directions of an existing measurement.

A strain gauge rosette is a term for an arrangement of three strain gauges that are positioned closely together in order to measure strains along different directions in the component under test. Use of multiple strain gauges enables global stress amplitude and phase to be determined. The rosette add-on calculates this global stress from a rosette measurement.

Many unforeseen events may occur during a measurement. Measuring an electrical or acoustic disturbance is common and can make analysis difficult. The additional Edit Signal tool allows the user to remove disturbing noise from signals. The user has two choices: Cut the signal or set the amplitude to zero.
