Assigned Department Objectives

Teaching Method

Outline:
General or Specialized : Specialization
Field of learning :Motion and Vibration
Foundational academic disciplines : Engineering/mechanical engineering/mechanical mechanics and control

Relationship with Educational Objectives of Advanced Course :
This class is equivalent to "(2) Acquire knowledge of specialized technologies such as material and structures,motion and vibration,energy and flow,infomation and measurment/control, design and production/magagement, and machines and systems, and acquire the ability to apply this knowledge to the design, policy, and operation of machines and systems".

Relationship with JABEE programs :
The main goal of learning / education in this class is "(A)", also "(A-2)"is involved.

Course outline :
The vibration of machinery and machine parts is an important issue in machine design because it causes problems such as mechanical strength and noise pollution. In this class, we will focus on the vibration of machines and their components and deal with the dynamic problems of machines.
Style:
Course method :
The lecture will be conducted mainly on the board. Students will learn how to solve differential equations, force, velocity, acceleration and moment. We will pay attention to solve differential equations and to deepen students' understanding of Newtonian mechanics such as force, velocity, acceleration, and moment.

Grade evaluation method :
Results of regular examinations are equally evaluated (70%). Quizzes, exercises and reports (30%). Students with an aggregate score of less than 60 points may be required to retake the examinations, which will be the same as the regular examinations. Students are allowed to bring their own notebooks and calculators to the exam. In the case of distance learning, the grading method may be changed.
Notice:
Precautions on the enrollment :
This is a class that requires study outside of class hours. A total of 45 hours of study is required per credit, including both class time and study outside class time. Follow the instructions of the instructor regarding study outside of class hours.

Course advice :
It is important to understand mathematics and physics, since the main topics are the equation of physical phenomena and the solution of linear differential equations.

Foundational subjects : Fundamental Differential Equations(3rd year),Mechanics I (3rd year), Mechanics II (3rd), Applied Mathematics II (4th year), Controlling Engineering (4th), etc.
Related subjects : Computational Mechanics (MS- 2nd), System Control Engineering (MS- 2nd), etc.

Attendance advice :
The equations in this course are linear differential equations, since this course mainly deals with 1D problems including rotation. The equations are linear differential equations, so students are encouraged to review the solutions of differential equations. The physical interpretation is based on industrial mechanics, so students are encouraged to review this as well. Students are expected to submit the report by the due date, and will be expected to be late for the class.
