Course description

The curriculum of the Department of Mechanical and Functional Engineering is organized around the three fields of energy, materials, and information. Mechanical engineering covers a wide range of research subjects, and there are many advanced academic fields that cannot be dealt with in ordinary lectures and exercises. "Seminar on Mechanical Engineering 1" deals with research themes based on the highly specialized fields of faculty members of the department. Students select one of the themes presented by the instructors (Ono, Aoki, Matsuniraku, Hashimura, Hosoya, Nagasawa (English-speaking)) and carry out the tasks given in each of the seven lectures.

Purpose of class

In "Seminar on Mechanical Engineering 1", students will study research themes based on the advanced specialized fields of the faculty members of the department, and voluntarily learn methods such as logical thinking, quantification, quantification, and scientific discovery.

Goals and objectives

Students can search the database for academic papers related to the target field.
Students can logically explain the trends in the objective field from the survey results.
Students can explain the issues in the objective field based on the quantified data from the survey results.

Language

Japanese(English accepted)

Class schedule

	Class schedule	HW assignments (Including preparation and review of the class.)	Amount of Time Required
1.	Guidance	Students should work on issues according to the guidance of the lecturers.	190minutes
2.	No.1 Optimal design of bridges using Solidworks, Instructor: Professor Shinji Hashimura Currently, the optimum design is required in all fields including automobiles and railways. In order to learn them, we will take up the bridge as a subject and use the 3D-CAD software SolidWorks to perform the optimum design. If face-to-face implementation is possible, a bridge with an optimal design will be manufactured, a strain gauge will be attached, and the stress will be measured to compare with the strain predicted by CAE and confirm the optimal design.	Students should work on issues according to the guidance of the lecturers.	190minutes
3.	No.2 Toward the sophistication of the transportation system, Instructor: Professor Sota Yamamoto Currently, there is a movement to actively introduce communication and information technology in road traffic systems, aiming to improve safety through inter-vehicle communication, advanced navigation systems, and intelligent automobiles. However, road traffic has many problems such as mixed traffic such as cars, pedestrians, and bicycles, high moving speed with respect to relative distance, difficult to avoid, and high traffic density.	Students should work on issues according to the guidance of the lecturers.	190minutes
4.	No.3 Consideration of the rotation mechanism of the radiometer and trial experiment, Instructor: Professor Naoki Ono We will take up a radiometer that has a simple wing structure, is supported in a vacuum glass sphere, and rotates when exposed to light, and its motion mechanism will be examined in terms of thermo-fluid engineering. In addition, we will discuss ideas and issues for making the rotor blades by each group, actually rotating them in a vacuum vessel to compete for rotation speed, and at the same time rotating them at high speed. In addition, this year, we will also measure and consider the relationship between the pressure value inside the container and the rotational force (rotational speed).	Students should work on issues according to the guidance of the lecturers.	190minutes
5.	No.4 NC processing by CAD / CAM, Instructor: Professor Takashiro Aoki In today's manufacturing, it is common to carry out CAD at the time of design and manufacturing by NC equipment. Therefore, understanding the mechanism of converting CAD data into manufacturing data for NC equipment is synonymous with understanding manufacturing by machine tools. In this theme, each person draws the initial characters and the production drawing of the task processed product and creates a processing program by CAM based on it. It is confirmed by simulation whether the product can be manufactured, and finally the aluminum is actually scraped. Through these, you can become a numerically controlled machine and learn about the relationship between CAD / CAM systems and NC machine tools.	Students should work on issues according to the guidance of the lecturers.	190minutes
6.	No.5　Design of Micro Electrostatic Comb Actuator, Instructor: Professor Sumito Nagasawa In this class, we design a micro electrostatic comb actuator which is the most reliable and efficient actuator for the field of Micro-Electro-Mechanical Systems (MEMS). In the small world, the actuator driven by the electrostatic induction becomes stronger than the actuator driven by electromagnetic induction. Since an actuator whose electrode shape is like a comb is easy to design, the micro electrostatic comb actuator is widely utilized in MEMS applications. At first we understand the driving theory and the micro fabrication process of the micro comb actuator, and then design an original comb actuator in each group. Calculate the generation force of the micro comb actuator and drawing its photo fabrication mask using a free layout editor. Select several good designs and fabricate them actually and then evaluate their dynamic characteristics. Schedule: Day 1：Introduction of this class; explanation of the driving principle of the micro electrostatic comb actuator, basis of the micro fabrication processes, make working groups, explanation for report tasks. Day 2：Explanation for types of the micro actuator and design methods for the micro comb actuator. Day 3：Explanation of usage of the layout editor. Discuss the original concept of the micro comb actuator. Day 4：Presentation of the article survey in each student. Day 5：Discuss the fabrication mask layout of the micro comb actuator. Day 6：Draw the fabrication mask layout and make a report of calculation for the micro comb actuator. Day 7：Presentation about the original micro comb actuator in each group.	Students should work on issues according to the guidance of the lecturers.	190minutes
7.	No.6 Dynamic design of structures (design and production of musical instruments), Instructor: Professor Naoki Hosoya The purpose is to learn about dynamic design considering the vibration characteristics and acoustic characteristics of structures through the design and manufacture of metallophones. First, learn the fast Fourier transform, which is one of the data processing methods required for vibration analysis, and learn programming with MATLAB to realize this. Next, we derive the exact solution of the beam and understand the eigenvalues and eigenvectors of the structure. Finally, it is shown that the metallophone with the desired vibration characteristics and acoustic characteristics could be produced by performing vibration measurement, acoustic measurement, and finite element method analysis (NASTRAN) of the manufactured metallophone.	Students should work on issues according to the guidance of the lecturers.	190minutes
