Developing technical skills andproblem-solving abilities to understand principles and apply them.
Various mechanical devices, from bullet trains and airplanes to space rockets, computers and home appliances, and artificial organs, require material functions, energy functions, and information processing functions. Our department aims to understand the basic principles of these three functions and acquire application technologies. Therefore, students learn about materials and mechanical properties necessary for machine manufacturing, principles and technologies of energy conversion, motion and vibration phenomena, and also study the design of elements and mechanisms that make up machines, assembly methods, and basic theories of information, measurement, and control. Many experiments and practical training are provided to cultivate the ability to think and solve problems independently.
Mechanical engineering is a discipline that realizes "mechanisms" useful to society. A machine is not just an object. Whether it is a small part or a large system, a machine has a "mechanism (function)". This mechanism means the structure or mechanism to realize the role given to the machine.
Mechanical engineers need the ability to conceive mechanisms, select materials as raw materials, design feasible structures and mechanisms, create entities through processing, operate them through control, and realize them as functions. In our department, students learn the basic items necessary when making and using machines thoroughly from technical principles to applications, and aim to acquire skills to integrate knowledge of machinery, electricity, information, etc. into systems.

I am conducting experiment-based research on the fatigue characteristics of metal materials. Many mechanical parts that repeatedly receive loads are destroyed by metal fatigue. I am working to elucidate the fatigue mechanism by identifying the fatigue life of metal materials and observing microscopic damage (cracks) generated in fatigue tests with a microscope.
Since various materials are used in machines, there are many unclear points in the mechanism of fatigue fracture. Many of the materials handled in research are special, and I face various challenges in test preparation and subsequent analysis. By tackling problem-solving by making full use of the wide-ranging knowledge of mechanical engineering I have learned so far, I have acquired qualities as an engineer.
