The responsibility of the Mechanical
Engineering is to develop mechanical engineers through the curriculum which
blends the academic expectations of students with the ever-changing trends
in modern industries. The department attaches importance to the fundamentals
of science and electronic technology as it attempts to develop skilled
mechanical engineers. The research activities generally involve four fields
of engineering.
Strength of Materials
This division is concerned with the research
and analysis of the dynamic strength characteristics of materials. Specifically
, this involves the analysis of stress on parts in operation by applying
the fatigue characteristics of metal foils; the analysis of stress on joints
of different materials under impact loads; image processing and Moiré procedures;
impact fracture and sound elastic stress measurements; and fatigue improvement
for material within their long-life region, as in materials like high-strength
titanium alloy.
Thermal Engineering and Fluid Engineering
The thermal engineering field pursues research
in heat transfer for flowing fluids in parallel plates with melting and
solidification; energy analysis related to latent heat storage; and combustion
analysis and efficiency improvement for internal combustion engines. The
fluid engineering field promotes research in radial flow between two paralleled
plates; impinged jet studies; the three-dimensional boundary layer on a
body in revolution; statistical analysis of turbulence data; and investigations
into the hydraulic transport of solids through pipes.
Production Engineering
Production engineering concerns the workability
and the high temperature strength of materials. Workability research is
concerned with the behavior of materials in forming and cutting processes;
the mechanism of defect occurrence; the deformation of materials; and the
numerical simulation of deformation and fracture. The study of the high
temperature strength of materials and development of new materials is concerned
with improving stainless steel alloy design through oxide dispersion strengthening;
heat resistance characteristics of oxidation resistant materials at super-high
temperatures; high mechanical properties of composite materials with SiC
whiskers; the microstructure and toughness of stainless steel; and the
improvement in the toughness of spherical graphite cast iron. There is
also research work on the analysis of welding heat input in friction welding.
Mechanical Systems
In mechanical systems, research activity
is focused in robotics and mechatronics.
The main concerns here are control of robot
manipulators with ultrasonic motors by means of pulse width modulation
and fuzzy reasoning; robot hands with fingers using ultrasonic motors;
highsensitivity liquid manometers using a laser diode under fuzzy control;
and the variable control of torque transmission by utilizing the movement
of magnetic fluid.
