Vibratory Power Transmission to a Reinforced Cylindrical Shell Structure
The vibratory power transmission to a reinforced, thin cylindrical shell is investigated theoretically and experimentally in the case of a mechanical excitation positioned on the reinforced part. The structure under consideration is built up from a semi-infinite shell coupled at its edge to a thicker shell of finite length (the reinforced part). Theoretical predictions based upon the Flügge theory are shown to agree well with measurement results. Results from a parametric study are also presented, showing the influence of the length and thickness of the thicker shell and the influence of the excitation position. It is revealed that a significant reduction of input power can be obtained by a proper design of the reinforced part.
