Description: Quasi-static models in multimodal analysis are approaches that assume that the systems being analyzed behave almost statically during the evaluation process. This means that, although the systems may be subject to dynamic changes, it is considered that these changes occur slowly enough for the system to reach an equilibrium at each moment in time. This approach simplifies the analysis of complex systems, facilitating the identification of vibration modes and their interaction. Quasi-static models are particularly useful in the study of various engineering systems, where loading conditions may vary, but it is expected that the system responds predictably. By using this methodology, engineers can perform simulations and make more accurate predictions about the behavior of systems under different loading conditions, resulting in more efficient and safe designs. In summary, quasi-static models are a valuable tool in multimodal analysis, providing a framework to understand and predict the behavior of complex systems under conditions that, although dynamic, can be treated as static in a specific context.
