Abstract

Now days, we often heard about some failure in structure of a building which leads to building collapse. This failure can be cause by a sound that creates vibration from a rotating machine which then was channeled to the structure. That’s why the vibration input power on a structure must be determined through the study. Reviews on the previous study of the related titles were carried out. The objective of the study is to model the vibration input power to a structure based on the mobility concepts using reception plate method. Other aims are to conduct experiment using reception plate method and to compare the result with direct measurement. However, the study is limited to an idealized receiver structure namely plate. Difference in phase excitation also might be ignored and phase from the force excitation is assumed to be uniform. The study contains the fabrication of the test rig which is used as the receiver. Besides fabrication, an experiment was carried out to obtain the input power. There are two method used which is the reception plate method and direct measurement. Therefore, a comparison between both methods was taken place to validate the data obtained. Finally, the whole elements in the study was conclude that the vibration input power from both method are almost the same and the reception plate method can be used as a valid method to determine vibration input power.
