Experimental Modal Analysis Using Impact Excitation
This test method characterises the dynamic properties of structures through experimental modal analysis using impact hammer excitation. The method measures natural frequencies, damping ratios, and mode shapes by striking the structure and recording the resulting vibration response. It is widely used in aerospace, automotive, civil engineering, and mechanical equipment development to validate structural designs and identify potential vibration issues. Accreditation ensures proper instrumentation calibration, correct measurement methodology, and reliable data interpretation for safety-critical applications.
What it measures
- Natural frequencies (modal frequencies)
- Damping ratios (modal damping)
- Mode shapes (displacement patterns)
- Frequency response functions (FRF)
- Coherence and data quality metrics
