DewesoftX 2022.3 Released - Modal Test Improvements, New Orbit Waveform Widget, IFFT Filtering

Modal test improvements

The Modal Test module now supports both relative and absolute ODS measurements. The Absolute ODS FRF function is also known as “phase-assigned spectra”, “PAS”, or “phase-referenced spectra”. The new ODS FRF output contains the magnitude of the response while having the phase between that and the reference response.

The relative ODS outputs are shown as the FRF H1 and H2 Transmissibilities, which have a magnitude related to the ratio between the response and the reference response.

The ODS measure display template is updated to use the new ODS FRF output for magnitude and phase spectra.

Another upgrade in Modal Test is that measured data does not reset when going back to channel setup, stopping and restarting the measurement, or reopening the Setup file after shutting your pc down. Already measured functions will persist and be stored in new data recordings unless manually cleared. This functionality also makes it possible to perform setup changes during test campaigns - you may conclude that more DOFs should be measured after the test has started.

New orbit waveform widget

The Orbit Analysis module now includes a new dedicated visual control - the Turbomachinery Domain Signature Waveform graph. This graph further strengthens the already versatile OA solution, completing the market’s most capable rotor dynamics tool. The waveform graph presents time domain data from each of the sensors used within a constant timespan, along with a clear indication of the zero pulses, allowing you to observe the start and stop of each period.

The scope of historical data can be shown in time or number of revolutions with freely definable duration or with the X axis supporting the display of time, revolution count, or angle. The Orbit Waveform Graph widget can also display a set of industry-standardized parameters, such as the direction of rotation and the sensor angle relative to the key-phasor (zero) position.

Time data filtered in the frequency domain with IFFT

The Frequency domain filter module now supports filtered synchronous time data channels. When you set the Filter type to “Custom…” and set the Output type to “Time Signal” - this performs processing including inverse FFT in the way that the output time data is the frequency filtered version of the input time data sample-by-sample. The filtered IFFT time signals can then simply be further processed and analyzed as time-synchronous signals.

High-DPI support

More and more modern displays now support high-DPI (dots per inch) resolutions, requiring software applications to adapt to such conditions. The new 2022.3 Dewesoft software package now natively supports high-DPI, ensuring properly-scaled controls, sharper fonts, and graphics when used on modern displays.

Additional columns in analog in grid

Within the Analog-In module, DewesoftX offers a channel grid that provides a complete list of currently available amplifiers with a simplified overview of their properties. This grid supplies numerous amplifier properties you can customize as columns, making a personalized channel overview. 

The new 2022.3 version brings even more amplifier properties that you can add to the grid,  mostly related to the Bridge measurement type (Bridge mode, Bridge Resistance, Gage factor, Poisson’s ratio, Young’s modulus, etc.). All newly added properties enable you to change their values ​​directly from the grid, which significantly simplifies the setup preparation and further extends the overview of amplifier settings.

What else is new?

• Search by CAN Message is presented in the CAN module, with the newly enabled Message column within the channel grid.

• In Analyze mode, the yellow cursor now aligns in time with the selected event from the event list. 

• An additional Wifi strength channel is now accessible as a system monitor channel.

• More temperature channels for IOLITE modules are now usable as system monitor channels.

• Another action block for setting the amplifier ranges is now included within Sequencer. 

• A new Reference-point plugin that calculates the position, velocity, and acceleration of a point offset from the point of measurement, is now at disposition.

You will find additional information on Dewesoft’s Customer Support Portal for the above-listed features.

DewesoftX 2022.3 is a free upgrade for all Dewesoft customers and is compatible with all Dewesoft data acquisition systems. You can download it from our download center, where you also find a changelog listing all the minor improvements and bug fixes.
