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.
