Course description and aims

Students in this course will learn about advanced issues within mechanical engineering through experience. Students will get first-hand experience with machines, conducting experiments on plastic working, vibration control, non-linear vibrations, self-induced vibrations, fuel cells, refrigerators, drag, and the velocity boundary layer, thereby deepening their understanding of mechanical engineering. Specifically, students will conduct experiments on plastic working and deformation properties of aluminum, active vibration control, properties of non-linear vibration systems and self-excited vibration systems, principles and characterization of fuel cells, vapor compression refrigerators, drag measurements, and measurement of the velocity boundary layer.
The main aim of this course is both to deepen students' understanding of mechanical engineering and improve problem identification skills, implementation skills and solving skills by conducting progressive experiments in mechanical engineering. In addition, students learn teamwork, leadership, communication skills, data collection, processing, and organization methods, observation methods, and how to write reports through these experiments.

Student learning outcomes

Students will acquire the following skills from taking this course.
1) Skills for explaining advanced aspects of mechanical engineering that cannot be learned just from classroom lectures
2) How to run experiments on advanced topics in mechanical engineering
3) Critical thinking skills, practical skills, and problem-solving skills
4) Teamwork, leadership, and communication skills

Competencies that will be developed

✔ Specialist skills Intercultural skills ✔ Communication skills ✔ Critical thinking skills ✔ Practical and/or problem-solving skills

Class flow

At orientation in the first class, the instructor will explain the frame of mind and suggestions for students' experiments, as well as composition guidelines for experiment reports. From the second class on, students will be divided into 7 groups, and each research topic will be worked through. Reports must be submitted by the deadline. In addition, students are required to carefully read the experiment manual in advance to ensure experiments are run safely and smoothly.
