Modal Analysis

ICR‘s mission is based on acoustic and vibration control as well as predictive maintenance of machinery based on the study of its dynamic response in operation.


In many cases, it is of particular interest to have in-depth knowledge of the dynamic properties of a system to propose solutions that improve its performance, reduce maintenance costs, increase its reliability or, in general, provide the system with greater robustness.


Modal analysis allows you to determine the dynamic response characteristics of a system to any excitation. By determining the modal model of the structure (natural frequencies, mufflers and modal deformations), the response of the studied set to any strain imposed can then be predicted from the contributions to the response in each of its own ways.


ICR performs numerical modal studies using FEM, and experimental, through experimental modal analysis, EMA, and operational modal analysis, OMA. Experimental procedures are particularly useful for determining the dynamic response of mechanical systems under real operating conditions, e. g. wind turbines, railway rolling stock or industrial machinery.


The exhaustive knowledge of the modal characteristics of a system makes it possible to carry out an intervention aimed at one of the predominant response modes of the system to control the overall vibration level in an efficient way.
