On this page, you will learn all the necessary steps to calculate Blocked Forces using the direct force method in SOURCE. At the end, you will find some additional steps that VIBES recommends performing to check the quality of your data.
To analyze your operational data, you need to import them into SOURCE. SOURCE supports ATFX and MAT files. You can do a bulk import of multiple files at once, by importing the folder that contains them all.
To import operational data, complete the next steps:
To do an analysis, you need to set up your channels. In particular, you have to:
Before jumping to the analysis, you need to set which channels SOURCE will use for the calculation, and set them as Masters.
To set the channels as Masters, you have to:
If this step is performed correctly, the channels will turn green. Numbers will also appear in the Mapped to column.
The next step consists of setting the correct channel type. For this type of analysis, you need to set the following type:
To change the channel type, complete the next steps:
Before doing the analysis, you need to set up the Virtual Points. In particular, you have to:
To calculate Blocked Forces, you first need to define Virtual Points. To do so:
After defining the Virtual Points, you need to add the VP Degrees of Freedom to the Master channels. To do so, complete the following steps:
After defining the Virtual Points, you need to check if it is positioned and oriented correctly. If not, you have to edit it.
To do so, complete the next steps:
After creating the new channels, you need to check whether they are of the correct type. If they are not automatically set as VP Forces, you need to edit the channel type, following the instructions above.
After importing the data and setting the channels, you can proceed to make the analysis and calculate Blocked Forces.
To calculate Blocked Forces, complete the next steps:
If you want to have multiple graphs on your page, you can customize the graphs’ page layout. See instructions here.
If you are not interested in the full dataset, but just in some portions, it is possible to extract the data of interest by cropping segments and merging them into sequences. This is only possible for Time Series.
To create segments and sequences, follow the instructions at this link.
To check your FRF data, you can plot them in the Graph card and visualize their overall magnitude and coherence in the Matrix Viewer. You can plot single FRFs or visualize the singular value breakdown, often referred to as Complex Mode Indicator Function (CMIF).
To plot FRF or CMIF, follow the instructions at this link.
You can display Operational Deflection Shapes of your operational data in the 3D Viewer. To access the 3D Viewer card in the Operational Data module, you need the src-ods license. To display ODS, follow the instructions at this link.
You can display ODS only after importing the geometries. At the moment, SOURCE only supports the geometries imported from the DIRAC project.
Operational consistency can be used to reveal incorrect behavior in the operational measurements, such as overloads, non-linear phenomena, moved or loose sensors and inconsistent sensor movement. It works by evaluating the consistency of the response data through the Virtual Point Transformation. To plot the operational consistency, follow the instructions at this link.
