碩士 === 國立成功大學 === 系統及船舶機電工程學系碩博士班 === 93 === The purpose of this paper is to use a unified approach to solve the free vibrations of uniform（or non-uniform）single-span（or multi-span） beam carrying various concentrated elements. The concentrated elements include the concentrated mass and the corresponding translational and rotational spings. In order to achieve the goal, consider a beam made up of different but uniform sections. Between the next two sections, we connect them with one node carrying the three concentrated elements. For the reason, we can just only change the section areas of every beam segment, and the situations of concentrated elements on every node to build various boundary conditions. Then we can take these math models to free vibration analysis.
