1. SEA experimental analysis
1.1 Need
SEA analysis describes the behavior of the dynamic system through a reduced set of energy equilibrium equations.
The first step in solving the problem is to determine the number of equations required, i.e. the number of subsystems to be created for an appropriate representation of exchanges. As we saw in that it is necessary for each subsystem to include several local resonance modes for it to constitute an independent element. If we have modal density and wavenumber formulas, we can quickly determine the substructuring scale when the system has a simple topology. A large number of systems can thus be reduced to a set of simple interconnected elements, and simple calculations can be used to build a robust model.
