Operational Modal Analysis – Modal Parameter Identification under Operating Conditions

Register now

Operational Modal Analysis (OMA) is used instead of Classical Modal Analysis (CMA) for accurate modal parameter identification under actual operating conditions and in situations where it is difficult or impossible to artificially excite the structure. From originally being developed for modal analysis of large civil engineering structures, OMA is today also widely used for mechanical structures such as vehicles, aircraft, ships, and machinery.


The webinar will:

  • Give an introduction to OMA
  • Give an overview of dedicated modal parameter identification techniques used in OMA
  • Show typical application examples of OMA for civil engineering and mechanical engineering structures
  • Provide guidelines for when to use OMA instead of CMA and vice versa
  • Introduce Structural Health Monitoring (SHM) and explain how techniques from OMA can be used for subspace-based damage detection
  • Show application example of damage detection
