Laboratory of Machine Elements
Professor / OHTA Hiroyuki
- Look into rolling motion from a scientific perspective
- Solving problems is the mission of an engineer
- Always think “why?”
Professor / OHTA Hiroyuki
Professor Ohta encourages each student to perform at a high level. He invites the students to think critically in order to advance their own research and is always present in the lab, so it is easy to discuss results, problems, etc.
Research Content
The Laboratory of Machine Elements conducts fundamental research on rolling motion and applied research on mechanical elements. Enhancing the performance of these elements directly contributes to improved energy efficiency in machinery. In collaboration with industry, the lab addresses practical issues such as vibration, heat generation, and tribology through experiments and analytical studies. To understand phenomena and develop solutions, the laboratory uses advanced computational tools, including TED/CPA(Tribology Engineering Dynamics/Contact Problem Analyzer), multibody analysis(MBA), and finite element method(FEM).

A Day in the Lab
A day in the machine elements lab starts with a morning seminar where each student gives a 5-minute presentation on their recent progress in research to the professor and other members, followed by discussion. During the seminar the professor instructs us on how to proceed with our findings and we then work on those tasks throughout the morning. After lunch, the professor comes to the lab to check on our progress and further discusses it with us. Once we are done, we gather our findings and prepare a presentation for the next morning seminar.
