Department of Mechanical Engineering Laboratories

Heat, Fluids (Heat)

Human civilization has always needed to convert heat to work (power) in the most efficient way possible and use it to effectively cool and warm spaces. This laboratory seeks to solve environmental and energy problems by clarifying phenomena and developing relevant technologies in numerous areas: the practical use of internal combustion engines and fuel cells that use bio fuels (through quantitative simulations); heat transfer; and high-temperature plasma fluids. The photo shows a mock test of re-entry of a space plane.

Heat, Fluids (Fluids)

This laboratory conducts experiments and numerical calculations to determine the structure of the flow between coaxial rotating cylinders and around rotating discs with the aim of applying the results to bearings for HDDs and artificial hearts. As well, research to measure speed and make relevant calculations is aimed at clarifying the phenomena of the complex changes in flow (turbulence) over time and space, such as that of the air and rivers in nature. Other research is aimed at determining macro flow from the standpoint of a microscopic movement, such as that of molecules. The photo shows disruption at the boundary of jet flows.

Materials, Intensity

Experiments, observations, and calculations are carried out on changes in surface nano-characteristics and crystal properties of materials. To determine the nano- and micro-phenomena of structural materials, this laboratory uses state-of-the-art equipment such as atom-force microscopes, ion beam instruments, and electron microscopy image analysis devices. Through a greater understanding of phenomena, we can improve the reliability and functions of the materials that make up things like vehicle-traffic-related equipment, power generating equipment, and electronic devices, and thus contribute to solving key issues in today’s world such as protecting the environment, saving energy, and helping create a safer and more economical society. The photo shows analysis of the nano- and micro-structure of materials.

Design, Production

Today’s society is witnessing lightning-fast technological developments and progress in areas such as hybrid, fuel-cell, and electric cars, IT, robotics, and outer space. It’s no exaggeration to say that this progress is thanks to highly advanced and mechanized production technologies. This laboratory conducts research into the manufacturing processing technologies and methods needed to bring about such advanced mechanization. The photo shows the inside of an HDD.

Motion Dynamics, Control

Through research in this laboratory, students acquire the basic knowledge needed to help humans and machines function in harmony. Research is aimed at developing new methods for designing the machines and equipment that work side-by-side with people; for example, by studying the reasons for the strength and distortion of metal materials, polymer materials, and compound materials; by clarifying biological information processing mechanisms and the characteristics of a human being’s functions; and by looking at what must be done to advance and improve rehabilitation and other medical equipment (such as wheelchairs) needed in today’s rapidly aging society.
