ISO 7626-2

Experimental Modal Analysis โ€“ Single-Point Excitation

ISO 7626-2 describes procedures for experimental modal analysis using single-point, single-axis excitation to characterise the dynamic properties and natural frequencies of structures and machines. This test method captures frequency response functions and mode shapes essential for structural design validation, vibration control, and fault diagnosis. Aerospace, automotive, civil engineering, and machinery manufacturers use modal analysis to refine designs and understand dynamic behaviour under operational loads. Accreditation ensures rigorous application of measurement protocols and data quality standards supporting engineering confidence in structural performance predictions.

What it measures

  • Frequency response functions (FRF) over specified frequency range
  • Natural frequencies (resonances) and modal damping ratios
  • Mode shapes and structural deflection patterns
  • Coherence and measurement quality indicators
  • Dynamic stiffness and impedance characteristics
