Structural dynamics

  • Operating Deflection Shapes (ODS)

    Operating Deflection Shapes (ODS) analysis is a very versatile application for determining the vibration patterns of machinery and structures under various operating conditions.

  • Classical Modal Analysis

    Classical modal analysis is used for modal parameter identification of structures under controlled boundary and environmental conditions using hammer or shaker excitation.

  • Ground Vibration Test (GVT)

    In aircraft ground vibration testing (GVT), large modal tests for different aircraft configurations on the ground are performed to update the flutter boundary predictions before the first test flight is made.

  • Operational Modal Analysis (OMA)

    Operational Modal Analysis (OMA) is used instead of classical modal analysis for accurate modal parameter identification of structures under actual operating conditions, and in situations where it is difficult or impossible to artificially excite the structure.

  • Structural Health Monitoring (SHM)

    By performing long-term continuous Structural Health Monitoring (SHM) it is possible to monitor and track a structure’s state and carry out condition-based maintenance to ensure structural integrity.

  • Test-FEA Integration

    Integrating testing and Finite Element Analysis (FEA) helps to cut development costs, reduces the number of physical prototypes, and shortens the time from concept to production.

  • Shock Response Spectrum (SRS)

    The Shock Response Spectrum (SRS) is used to determine the damage potential of components and systems from transient events, such as pyroshocks, in order to ensure their survival in known environments.
