Boundary conditioning technique for structural tuning

Boundary conditions of a structure will strongly influence their natural fr equencies. By controlling the conditions at the boundaries in a non-homogen eous and non-uniform fashion, it is shown that the structural natural frequ encies can be manipulated in a favorable fashion. The technique is named bo undary conditioning. An analytical model has been developed for a plate typ e structure to illustrate the boundary conditioning technique. The results are presented and discussed, along with references to steel pan tuning. (C) 1999 Academic Press.
