Software
Development. I am experienced in
several programming languages: C for
DOS, MS Visual C++ for Windows, Borland C++ for Windows and Java, and know very
well about Data Structure, Computer Graphics, and the data formats especially
used in RP technology, STL and CLI. Until now, and
has developed four integrated software, all of them fulfill the functions
of data processing, machine monitoring and process control, etc.
Every software system has an easy-to-use user interface.
Electromechanical Product
Development. Electromechanical product is a kind of integrated system, which
is the synthesis of computer, microprocessor, mechanics, electronics, sensing
techniques etc. Until now, I have
successfully developed four integrated electromechanical systems; each of them
is composed of several subsystems, for instance, position sensing and control
system, temperature sensing and control system, force and displacement sensing
and control system and so on.
Research on Product Development
Methodology. Product development works on its distinct principles, which can
apply to various development activities. Based on his comprehensive knowledge
background and abundant experiences of software design and electromechanical
product development, I have deeply studied the product development methodology
and developed a theory named “ Product Development Kinetics”.
Research on Technology of Rapid Prototyping. Rapid Prototyping is a kind of advanced manufacturing technology, which can produce 3-D parts directly from CAD model. Three of the four integrated systems which I have designed are RP&M system and are experienced in RP software design, RP system development, process study and material research.
Experimental system of 3-D
Welding. As a Postdoctoral
Fellow in Southern Methodist University,
Large Scale RP&M System ---SSM-1600.
While studying as a Ph.D. candidate in
Multi-functional RP&M System ---MRPMS. While
Studying for my Ph.D. degree in
Tension Test Machine for Metal
Sheets. While studying for master degree in
Selective Chemical Liquid
Deposition for Mini-structures and Microsystems (SCLD-MEMS). This
is an innovative manufacturing technology to make micro-electromechanical
component and system. SCLD-MEMS integrate chemical liquid deposition, rapid
prototyping technology, systems and control, and mini-structures and
micro-systems in one automatic process. Droplets of organometallic compounds
solutions are injected through a precise nozzle, and decompose to produce solid
materials when touching a temperature-controlled hot substrate. By controlling
the motion of the nozzle and the spray time, a desired 3-D shape microstructure
of deposited material can be formed through layer-by-layer scanning technique,
in this way a functional MEMS component can be made.
I am the leading researcher of this project.
An Innovative Bionic Manufacturing
System for 3-D Bone Scaffold and Tissue Structure. This project is aimed to
make composite bone scaffold, which integrates biomaterials research, bionic
modeling, solid freeform fabrication, systems and control, and bone scaffold
tissue engineering in one intelligent system. The Bionic Manufacturing System is
based on the following principles: First a CAD model of bone is created based on
the images of computed topography (CT) or magnetic resonance imaging (MRI) and
bionic internal structure modeling using revere engineering; then a special
designed sucrose material is used to create a skeleton which has the negative
structure of bone Extra-Cellular Matrix(ECM) voids using Solid Freeform
Fabrication technology (SFF); and then composite of polymer and ceramic is cast
into the sucrose negative skeleton and air-solidified; the sucrose skeleton is
then removed using water; and finally the bio-composite scaffold is sintered at
low temperature to improve the mechanical integrity and strength. I am the
leading researcher and co-PI of this project.
