Class Objectives
/Class Outline The course will provide fundamental knowledge of vibrations in linear mechanical systems with a single and two degrees of freedom. Students will acquire the following knowledge:
1) How to derive equations of motion according to Newton’s second law of motion
2) Free vibrations in 1DOF and 2DOF systems without/with damping
3) Forced vibrations in SDOF and 2DOF systems without/with damping
4) Principles of vibration isolation

Class Schedule Class 1: Introduction to Mechanical Vibrations
Class 2: Newton's Laws of Motion
Class 3: Free Vibration of Undamped One Degree-of-Freedom (1DOF) Systems
Lesson 4: Free Vibration of Undamped 1DOF Systems
Lesson 5: Forced Vibration of Undamped 1DOF Systems
Lesson 6: Principle of Vibration Instruments (Vibrometer, Accelerometer)
Lesson 7: Exercise Problems
Lesson 8: Mid-Term Examination
Lesson 9: Free Vibration of Damped 1DOF Systems
Lesson 10: Forced Vibration of Damped 1DOF Systems
Lesson 11: Free Vibration of Undamped 2DOF Systems (Equation of Motion)
Lesson 12: Free Vibration of Undamped 2DOF Systems (Modes of Vibration)
Lesson 13: Forced Vibration of Undamped 2DOF Systems (Resonance, Vibration Absorber, Vibration Isolation)
Lesson 14: Free Vibration and Forced Vibration of Damped 2DOF Systems
Lesson 15: Exercise Problems

Mid-term and end-term examinations will be held. Report assignments will also be given.

Suggestions on
Preparation and
Review   Students should steadily work on exercise problems assigned each week. Engage your imagination to discover links between equations and real-world physics, rather than merely getting absorbed in manipulating equations.
  It is strongly recommended that the students use Mathematica, which is freely available for Hiroshima University students. Install it through the instructions on the following page:
https://www.media.hiroshima-u.ac.jp/services/license/mathematica/

Requirements

Grading Method Grading will be made based on the written mid-term examination  (40%) and final examination (40%) and the reports (20%). Credits will be given to students who gain scores over 60%.
