中文摘要 | 本文在橫向磁場的影響下,考慮簡支樑的小變形振動。因此在振動過程中,簡支 樑受到磁力和磁力矩的作用,其方程式的推導是依據罕米吞原理。在本文中阻尼因數也同時 列入考慮,而橫向磁場的振盪所產生的頻率共振影響,在本系統中也被探討。使用Runge- Kutta的方法,振幅對時間和速度對振幅的圖表結果,亦分別被繪出。 |
英文摘要 | Transient vibrations of a simply supported beam under transverse magnetic fields are considered. Including magnetic force and magnetic couple, the equation of motion is derived by Hamiiton's principle. The damping factor is also considered in this study. The frequencies of oscillating transverse magnetic fields are applied to the system. Using Runge-Kutta method, the amplitude versus time and velocity versus amplitude diagrams are determined. |
