Processes can start with raw time data and/or spectrums/orders/FRFs etc
Data can be conditioned including filters, detrending, segmenting
Processing options include spectrums, FRFs, orders, statistics.
Output options include Excel, Powerpoint, etc.
This article has example videos and highlights of several different processes: 1. Calculating and Comparing Orders and Overall Levels 2. Averaging Multiple Channels with Block Calculator 3. Modulation Metrics 4. Data Validation 5. Rosette and Critical Plane Analysis 6. Early Detection of Bearing Faults 7. Exporting Processed Results to Excel
1. Calculating and Comparing Orders and Overall Levels over Multiple Runs
In this process, raw time data with rpm data is processed into orders and overall levels. Averages are calculated over multiple runs. Key methods include Spectral Map, Orders Sections, Overall Level, and Run Average.
Figure 1: Simcenter Testlab Neo Process that calculates order, overall level and averages over multiple runs.
This process shows how the spectrums of multiple channels can be averaged together. Different means (selecting specific channels versus using wildcards *) for selecting the data are shown with the Block Calculator method.
In this process, the amount of modulation (periodic rising and falling in level of a signal) is evaluated using several different methods: "Envelope", "Modulation Spectrum", "Modulation Map", and "Modulation Depth". The human response to modulation is also calculated using "Fluctuation Strength" and "Roughness" methods.
In this process, an automotive braking data validation process is explained in detail. In this case, specific data is extracted by creating an "Index channel" (has a value of 0 or 1 depending on criteria applied versus time) using the "Calculate" method. The "Decompose" method is used to reassemble the extracted data for further processing. Statistics are then calculated from the extracted data.
Simcenter Testlab Neo Process Designer has multiple ways to analyze measured strain gauges. This process shows how to use the "Rosette" and "Critical Plane" methods.
This process highlights how both measurement functions (spectrums, etc) and statistics can be exported to Excel in Simcenter Testlab Neo Process Designer.

The "Report to Excel" method is used in these processes.
