Modal Exciters & Amplifiers
Experimental modal analysis, or modal testing, is a process for physically obtaining a math model of a structure’s dynamic properties. Modal tests identify a structure’s modal properties: natural frequencies, mode shapes, mass, stiffness and damping. Modal test results help troubleshoot resonant excitation from operating forces, validate and verify finite element models, predict the benefits of structural modifications, support design verification, and understand structural responses due to complex loading conditions.
