| Course description |
|
Making appropriate physical model of dynamic behavior and vibration properties of the mechanical system is very important. In this lecture, based on the fundamental knowledge about single degree of freedom model, two/multiple degrees of freedom model are discussed. This is the major subject of this course. |
| Expected Learning |
|
The standard of this lecture is to understand a vibration analysis of 2-degrees of freedom system and a modal analysis of multi-degrees of freedom system. See the Curriculum maps. |
| Course schedule |
|
Based on the fundamental knowledge about single degree of freedom model, two/multiple degrees of freedom model are discussed. Details are shown below. 1 Guidance and review of the lecture of Machinery Dynamics I 2 Vibration of two degrees of freedom model Vibration without damping (Linear motion) 3 Vibration of two degrees of freedom model Vibration without damping (Rotation and coupling model) 4 Solution of free vibration 5 Solution of forced vibration (Without damping) 6 Solution of forced vibration (With damping) 7 Design of suspension system and dynamic damper 8 Examination 9 Equation of motion of multiple degrees of freedom system 10 Equation of motion of multiple degrees of freedom system by Lagrange equation 11 Natural frequencies of multiple degree of freedom system 12 Modal analysis 13 Utilization of modal analysis 14 Free/forced vibration of multiple degrees of freedom system 15 final examination |
