Modal Analysis

 

 


Modal analysis is defined as the study of the dynamic characteristics of a mechanical structure. The three parameters that comprehensively described the dynamic characteristics are: 

  • Natural frequencies,
  • Mode Shapes, and
  • Damping.

Knowledge of these characteristics provides insights into the dynamic behavior of the structure and its mathematical model, allowing for:

  • The prediction of the system response, and
  • The change in structural dynamic behavior with the change in geometrical properties, material properties, and boundary conditions of the structure.
