Roving sensor measurement is a test where the structure is excited at the same location while responses are measured on the structure at multiple locations. This type of measurement is performed, for example, when you do not have enough sensors to measure responses simultaneously at all the points of interest.
To perform a roving sensor measurement you will have fixed excitation points, while the accelerometers will be moved (roved) to new positions in the structure at each measurement. To perform a roving sensor measurement in DIRAC, you need to make an import campaign, thus you need the DIR-Import license.
The workflow includes three steps:
The master file is a DIRAC project containing the complete design of experiment of the test, including all excitation and sensor positions.
To set up the master file, complete the next steps:
After creating the master file, you need to perform all the measurements, with the sensors placed in all the roving positions. For each single measurement, you will need to save a copy of the master file.
To perform the first measurement, complete the next steps.
These steps must be repeated for each roving measurement.
To merge all the single measurements, you need to start an import campaign using the master file as base and import all the single measurements, correctly mapping channels and excitations.
To merge the measurements, you need to:
To merge all the measurements, you first need to create an import campaign, using as base the master file.
To create an import campaign, complete the next steps:
To import all the single measurements, complete the next steps:
After importing the single files, you need to correctly map the sensor channels and the excitation to the corresponding ones.
To map sensor channels and excitations, complete the next steps:
