Mechanical Engineering

The responsibility of the Department of 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 field 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 acoustoelastic stress analysis; 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.
