BOUNDARY CONDITIONING TECHNIQUE FOR STRUCTURAL TUNING

Boundary conditions of a structure will strongly influence their natural frequencies. By controlling the conditions at the boundaries in a non-homogeneous and non-uniform fashion, it is shown that the structural natural frequencies can be manipulated in a favorable fashion. The technique is named boundary conditioning. An analytical model has been developed for a plate type structure to illustrate the boundary conditioning technique. The results are presented and discussed, along with references to steel pan tuning.
