| Abstract: | Vibration power ratio is needed for knowing how much noise is transmitted from one part of a complex plate-cylindrical shell structure to another; it is essentially a ratio between the vibration power of one part to that of another part when one of the two parts or a third part of the complex structure is excited. In section 1, we use past research results on average mobility method to derive eqs. (1) through (6) for computing any vibration power ratio of our complex structure. We conducted experiments. Figs. 3 and 4 compare theoretical results (smooth solid curve 1) with test results (broken dotted line 2 connecting test points) and the fairly good agreement of computed values with test data indicates preliminarily that eqs. (1) through (6) derived by us can be used for computing vibration power ratio. |
