Components
Excitation unit
The broadband excitation is carried out with an automatic modal hammer
- Frequency ranges up to 40kHz
- Impact forces up to 2500N
- High reproducibility
Vibration sensor
The AMA can be operated with the following vibration sensors
- Laser Doppler vibrometer
Measurement data acquisition
4-channel measuring system with synchronous scanning
- AC, DC and IEPE coupling
- Anti-aliasing filter
- 24-bit resolution
- Frequency ranges 1 to 100kHz
- Frequency resolution 100 to 26500 FFT lines
Windows PC
- Standard or industrial PC, also according to customer requirements, with Windows 10/11
Software
The AMA software controls the entire measurement process to perform an automatic, experimental modal analysis.
Specification of the measuring equipment
- Frequency range 1kHz to 2MHz available
- Frequency resolution (number of FFT lines) selectable
- Graphically image-supported definition of the measuring points
- Automatic measuring process (scanning of the measuring points)
- 3D animation of the natural and operational vibration shapes
Measurements for a test object
- Measurements on a component with different numbers of measuring points
- Measurements on a component with different measurement settings (frequency range, FFT lines, number of averaging, excitation signals, etc.)
Automatic measurement procedure
- Triggering the automatic modal hammer
- Measurement of the excitation force and the vibration response
- Averaging and analysis
- Natural frequencies, natural shapes/operating vibration shapes and damping
Report creation and output of results for each job as a table
- Printer, PDF, Excel, CSV, AVI etc.
