Mechanodesign

mechanodesign1This program functions in close cooperation with the “Master of Mechanophysics” course. Sights are set on educating research engineers who will play important roles in sustainable manufacturing in the 21st century. Education and research are conducted with one eye on “sustainability,” “intelligence,” and “robustness.” Practical research is conducted in such a way that the essence of various tasks and the demands of society are appropriately understood, and that new values are created through solutions based on state-of-the-art technologies. By means of this practical research and graduate school education, the following are put into practice: education and research pertaining to “practical value creation,” whereby it is possible to design innovations in which full use is made of advanced engineering knowledge on a cross-sectional basis.
We train competent mechanical engineers and researchers who are familiar not only with mechanical engineering but also with wide-ranging state-of-the-art technical fields, and who have the ability to deal with the creation of new values through cross-sectional use of the above, and who can play globally active roles. Sights are set on training competent persons who actively oversee needsoriented manufacturing activities for “creating new values through practical approaches” as project leaders in corporate design or manufacturing departments

Laboratory Information

Fracture and Strength of Advanced Materials laboratory Metal Forming laboratory
There have been significant advances in the efficiency of all kinds of mechanical products in an attempt to reduce greenhouse gas emissions and to suppress energy costs.
Improving the efficiency of aircraft and automobiles, however, is only possible with the use of enhanced high strength and high function materials.
From this perspective, we conduct research on the strength and functionality of cutting edge aluminum alloys, titanium alloys, stainless steels and composites, as well as dissimilar material bonding and surface modifiers, and then use dislocation dynamics simulations to explicate fatigue phenomena.
Expertise gained through this research is returned to society by the acquisition of intellectual property rights and through academic society activities, and we also work hard to support industrial manufacturing activities.
We particularly expect our master students to acquire the essential understanding by taking turns to read and explain theories to each other and by making presentations to academic societies, so that they can go on to become top-class engineers and researchers.
Metal forming is the deformation of a material to create a new and different shape.
Metal forming can be subcategorized into raw material manufacturing techniques such as rolling, extrusion and drawing, sheet forming for metal sheets; and bulk processes such as forging, separation, joining and forming. Our group mainly focuses on thin sheet metal forming and our main activity is the development of new metal forming techniques. We also conduct research on understanding shearing and other process mechanisms, as well as related metal forming and melting and bonding processes. Research activities of master students consists mostly of experimentation. In this research, students are responsible for the whole range of activities, from design, processing and manufacture of the test equipment, components and test pieces, performing the experiments, and finally through to collating the test data.
Precision Manufacturing laboratory Micro/Nano Processing laboratory
While extremely ancient, gears are the optimum mechanical element in the field of mechanical engineering. We focus on gears and conduct research on gear cutting, finishing, and surface treatment while also conducting research on accuracy and performance evaluation. We have also expanded our research to cover challenges being faced in designing for strength and tooth profile design. Our main research projects are shown below:
① Development of hypoid gear tooth cutting condition setting systems using artificial intelligence;
② Research related to evaluation of DLC film sliding and rolling strength;
③ Development of tooth contact evaluation systems using artificial intelligence;
④ Research related to durability performance evaluation of plastic gears;
⑤ Development of face gear design systems;
⑥ Mechanical system vibrational analysis;
⑦ Development of gear failure precursor detection systems; and
⑧ Development of vibration control systems using neural oscillators.
We conduct education and research on micro/nano processing, which is a key technology for the creation of cutting edge machinery and instrumentation.
We provide education in the specialized knowledge related to the micro-processing that supports cutting edge manufacturing, while also conducting research in microscopic electrical discharge processing, nano-forming, and mirror finishing processes. In the area of microscopic electrical discharge processing, we are working hard to find the minimum possible processing dimensions and are now trying to manufacture the smallest possible diameter machining tool. We then use these tools to conduct research in micro-processes such as drilling, end-milling, and ultrasonic processing. We are also progressing with research on creating miniaturized surface structures using electrical discharge processing and nano-forming. We are involved in research into micro-processing methods to create miniaturized surface structures that can control the surface functions of a substance.
Production Systems Engineering and Informatics laboratory Robotics laboratory
People may be surprised to hear, but knowledge in the field of computer science algorithms is extremely important for improving the basic theories of production and logistics management. Some examples are theories to explain the difficulty in calculating the real nature of an issue, and ways to evaluate algorithm design and computational complexity. Many recent cases have been identified where if it is difficult to calculate an optimum solution in polynomial time, an approximate solution not so far from the optimal solution can be calculated more efficiently by effective use of a combination of problem structure. In the Laboratory of Production System Science, we focus on scheduling theory and conduct our education and research using an algorithmic approach to issues related to the optimization of process and routing plans. Robots function in a wide variety of environments and they can do this by mechanically incorporating and then controlling the dynamic functions of a variety of organisms to handle these changes in environment.
We center our research on robotics and system control engineering. We have taken the dragonfly as an example organism and are developing a robot that can fly in the same way, while using system control theory to conduct research on the issues confronting the control of lightweight multi-joint manipulators. We also conduct research on flying robots that travel in the air and along the ground with the same mechanisms. In addition, we conduct research based on limit cycles, brain and neuroscience, nonlinear system theory, probability system theory, and optimized control engineering to approach the challenges from theoretical, software and hardware perspectives and achieve mechanical devices with smooth and adroit movements.
Measurement System laboratory Smart Structural Systems and Structural Intelligence laboratory
To achieve a rich and content human society, we need to be able to quantitatively evaluate a huge range of physical phenomena and function, such as the performance of everyday industrial products and their manufacturing processes, or even more importantly, the state of health of us humans ourselves.
Here at Measurement Systems, we focus on 3D measurements, photo-application measurements and image processing measurements, and conduct education and research on new optical measurement techniques to better understand complex phenomena concerning mechanical and biological materials and flows.
More specifically, we are developing digital optical image measurement methods where we use computers to perform optical theory analysis on images observed with laser illumination, and then automatically measure the spatial information of the target object. We are also developing measurement applications for electron speckle imagery, and multi-dimensional flow measurement using moving image analysis.
Founded on technologies based on vibration mechanics theory, we conduct research on intelligent structural systems that can adapt to the surrounding environment, as well as having self-diagnostic capabilities. More specifically, by embedding nerves (sensors) and muscles (actuators) into the structures, we are researching adding such capabilities as controlling vibration and noise, recovering unused energy from the environment (energy harvesting), as well as monitoring structural health. Furthermore, we are working on smoothly and effectively utilizing nonlinear and passive characteristics in the interaction between materials, structures and the surrounding environment, as well as energy conversion mechanisms, to create smart structural systems.
