Course description
Vibration engineering covers vibration phenomena of mechanical systems (e.g. machines or structures) that are assumed to be a single-degree-of-freedom or two-degree-of-freedom system as an introduction against undergraduate students.
Purpose of class
To realize a dynamic design of mechanical systems with desired performance, students should learn to express and solve differential equations of motion of mechanical systems with a single-degree-of-freedom or two-degree-of-freedom.
Goals and objectives
  1. To understand the derivation and solution of differential equations of motion
  2. To understand the theory of free vibrations with or without damping
  3. To understand the theory of forced vibrations with or without damping
  4. To understand the analysis of mechanical systems with a two-degree-of-freedom
Language
