The limitations of the finite element method (FEM) mainly on numerical dispersion errors and on model dimension indicate that an alternative deterministic approach is necessary for the coupled vibro-acoustic analysis in the higher frequency range. Therefore, a novel approach called the wave base method (WBM) is discussed since it requires no meshes, and subsequently provides no dispersion errors and small model dimension. A 2-dimensional WBM code is then developed, and some examples are solved to show some advantageous features of the WBM. Moreover, a simple vibro-acoustic simulation on spacecraft is demonstrated, and local responses can be obtained due to its deterministic characteristic. It is also shown that the WBM has high potential for the vibro-acoustic analysis with the wide frequency range.
