Precise excitation without mass-loading
To achieve consistent transfer functions in experimental modal tests, an excitation source with repeatable force level is key. The unrivalled repeatability of the SAM Scalable Automatic Modal Hammer perfectly matches PSV Scanning Vibrometer needs. Two models allow for excitation of small and large structures with force ranges up to 222 N and 2.200 N. Use the SAM Scalable Automatic Modal Hammer for precision excitation without mass-loading in modal testing and modal analysis.
Highlights
- Repeatable excitation avoids double hits
- Precise force level control enables structural linearity checks.
- Reproducible position and angle for consistent transfer functions
- Bandwidth > 40 kHz for lightweight structures.
- Force levels from 1 N to 2200 N also excite large structures.
- Adjustment of the operational hit angle to excitation from all directions
- External trigger option for acoustic quality control
- Expanded operating temperature range from -20 up to 120°C (-4° .. 248°F) for climate chambers etc.
Automatic excitation for modal testing
The Scalable Automatic Modal Hammer type SAM1 is a tripod mountable actuator for sample excitation in experimental modal analysis and acoustic quality assurance with force levels up to 222 N, specially designed for lightweight structures and confined spaces. The software-controlled stepper motor allows for a high definition control of all relevant parameters and the travel of the hammer arm featuring the integrated force transducer.
SAM3 is designed for the excitation of larger samples in experimental modal analysis and acoustic quality assurance with force levels up to 2200 N. The software-controlled stepper motor allows for a high definition control of all relevant parameters of the impact of an instrumented modal hammer.
The SAM GUI Professional is used for convenient parameterization of the automatic modal hammer. Application-oriented features, such as the control of the impact angle or a remote control for precise set-up, enable practically every test setup.
