Course content
When we analyze the vibration of mechanics or structures, they are often regarded as a linear dynamic system. However, in case of large displacement or nonlinear damping, they have to be regarded as nonlinear dynamic system. In this lecture, the characteristics and analyzing methods of nonlinear dynamic system are discussed.
Purpose of class
The purpose of this class is for students to learn analytical, experimental, and numerical treatment of nonlinear vibration phenomena. Topics include nonlinear oscillator analysis (Perturbation method, harmonic balance method and Graphical method), jump phenomena, and self-excited vibration.
Goals and objectives
  1. Students who complete this course should have a clear understanding of nonlinear dynamic system.
  2. Students will analyze nonlinear vibrations and will develop mathematical techniques.
  3. Students will recognize the characteristics of the response of nonlinear dynamic system.
