Cooperating graduate schoolThe Graduate School of Mechanical Engineering initiated cooperation with the National Institute of Advanced Industrial Science and Technology (located in Tsukuba) on June 1, 2006. We are working together on research and education of energy systems relating to fluid machinery and flow control. Master's course students can conduct research at the National Institute of Advanced Industrial Science and Technology at the same time as studying at Tokyo Metropolitan University. See the section on cooperating guest faculties for research projects.

Mechanical Structure and Materials Engineering

Materials and Manufacturing Processes—The aircraft engine and the turbine rotor blade of the power generation gas turbine are received flue gases that exceed 1500°C and rotate at high speed. To improve fuel efficiency and reduce emissions from gas turbine, Turbine Entry Temperatures (TETs) of the aero engine have risen to 1700°C. But engine designers are looking for TET of 1800°C in order to increase engine efficiency. Materials developments in all turbine components, combustors, blades, and discs, are critical to achieving this. The Ni based superalloys are used for the turbine blades and rotors used under such a severe environment. The single crystal blade of excellent Ni based superalloy in the creep property is put to practical use in the aircraft engines. We focus on understanding the fundamental mechanisms determining the mechanical properties of aero engine materials. A polycrystal Ni based superalloy of the turbine disk material and a heat-resistant Ti alloy of the compressor disk material are also being researched.

Composite engineering—We have studied a damage tolerance design for high pressure composite vessels of fuel-cell cars and the laminated structure of fiber reinforced plastics to facilitate a highly reliable design for composite structures. We also promote research such as the multi-functionalization of fiber-reinforced composite material by using interphase control, the optimum design of medical fixation devices using bioabsorbable plastics, the material design of green composites, and the development and assessment of metal matrix composites via the squeeze casting method.

Nondestructive Materials Proof Engineering—Based on ultrasound, especially the evaluation of microfractures, and via the use of acoustic emission techniques, we have developed a hybrid proof test featuring a cross between nondestructive inspections and proof tests. In addition, we have also studied bioceramics for artificial joints, the assessment of long-term reliability for biocomposites, and thermal shock fractures for ultra-high temperature ceramics and CMC (ceramic matrix composites). Moreover, we have developed high performance materials by using surface modifications on the material, such as the implantation of high energy ions and coating.

Fluid engineering—We attempt to clarify the new drag reduction in the laminar flow area by using a highly water repellent wall, combining the wall-microstructure and water repellency. We have also investigated and analyzed fluid behavior in close proximity to the wall (nanoscale area from the surface) by using evanescent wave illumination. We try to reduce turbulent drag and clarify the rheological character by using surface-active agents and polymeric aqueous solutions. We have developed a flow control device enabling the use of a plasma actuator. We try to reduce turbulence and clarify the mechanism by using a soft surface structure.

Heat and mass transfer in microscale—Simultaneous imaging of temperature and concentration in microchannels using near-infrared spectroscopy: This is a remote, marker-free, and convenient method. The principle is based on the temperature dependence of the near-infrared absorption band of water. The laboratory is investigating chemical reactions, thermogenesis, mass diffusion, and thermal diffusion at merging points and interfaces in microchannels.
Mechanical System Engineering

Control Engineering—Since nonlinearity in our systems and time-delay in systems such as information delay or other factors affect the uniformity of system behavior, it is important to establish a system control theory that includes nonlinearity, time-delay and other such factors. We have primarily studied nonlinearity and system control theory construction for nonlinear systems, including time-delays. That study also includes the control theory for Networked control systems (NCS), the theoretical analysis for synchronization and anticipatory synchronization in the late-binding complex systems, as well as the technological application of the same.

Biomechanics and Rehabilitation Engineering—My research interest is gaining an understanding of the biomechanical characteristics of human movement, such as walking, and its practicalapplication, particularly to rehabilitation engineering. Examples of my research topics are as follows: biomechanical analysis of human movementusing motion captured data and a musculoskeletal model; a computer simulation model synthesizing human motion; development of a system and equipment for rehabilitation engineering. These studies related to human are conducted as a good application of mechanical system engineering. That is, a theory of human body dynamics is expressed using a multi-body dynamics.
