Course Description (中) 本課程內容包括一維與多維度振動系統解析,運用牛頓力學與能量法分析系統振動行為,同時亦包含在時域空間及頻率空間之觀念與分析技術,特徵值與特徵向量對應自然頻率與振型問題之解析。
(Eng.) This course includes the basic concepts and solution methods to one-degree-of-freedom to multi-degree-of-freedom vibrating systems. The Newtonian and energy methods are utilized for the analysis of vibrating systems. The analysis of vibration behaviors are employed in time domain and frequency domain. The eigenvalue problems associated with the natural frequency and mode shape are discussed.
