CAE - Modal Analysis Services

If a product has components that are noisy, exhibit unwanted vibratory behavior, or experiences unexpected vibrations, a Modal Analysis would help us understand where the problem might be coming from.

Through Vibration Modal Analyses we help determine a structure's natural frequencies or resonance frequencies (also called eigenvalues) and mode shapes (called eigenvectors).

Advantages of Outsourcing Modal Analyses to O2I

  • Wide industry experience in analysis of large structures with complex joints or structural members
  • Engineers with expertise in Modal FEA, experimental vibration and modal testing
  • Proficient in using Bruel and Kjaer, Prosig and Agilent testing systems with a wide variety of transducers
  • Exposure to noise testing and analyses in conjunction with modal and thermo-structural FEA

Modal Analysis Methodology at O2I

To carry out modal analyses, it is important to accurately model stiffness, mass, damping and mass distribution to reflect the structure's modal behavior. Our experience in experimental modal analysis and vibration testing of components help us understand the behavior of joints, contact conditions and other behavior to model behavior of structures. Analyses of mode shapes and natural frequencies are carried out and subjected to quality checks to ensure correctness of modeling.

If the structure experiences excitation at or near the resonance frequencies, the amplitude of vibration during oscillation or rotation can be large and can pose danger to the product life and to people in the vicinity of the structure. In such cases, vibration Modal Analyses are conducted and suggestions are usually made to change the structure's stiffness, mass or damping to -

  • Control the amplitude during resonance to a minimum, or
  • Shift the region of resonance to outside the region of intended use / excitation of the product
