摘要: In this paper, an underwater structure is modeled as a cylindrical shell with internal bulkheads, and closed by truncated conical shell, it consists of metal substrate sound absorbing coating, whose FGM core considered. Suppose the inner cavity outer space are filled air fluid mediums, mechanical response calculated Galerkin method while acoustic investigated means Helmholtz integral. Some numerical examples given effect geometrical size material parameters on discussed.
