3D solid model to replace the center layer model
The

of
the
center

model.
The
user
must
first be thin-walled plastic products abstract into approximate
plane and curved surface, the surface is called the center layer.
In
the
center

to
generate
two- dimensional
planar
triangular meshes, the use of these two-dimensional triangular
mesh finite element method, and the final result of the analysis
in the surface display. Injection product model using3D solid

abstraction
of
the
center

is
a
very difficult job, extraction process is very cumbersome and
time-consuming,
so
the

it
has
become

HSCAE3D is largely accepted3D solid / surface model of
the STL file format. Now the mainstream CAD/CAM system,
such
as
UG,
Pro/ENGINEER,
CATIA
and
SolidWorks,
can

is

Finite

methods
Injection molding products are thin products, products in
the thickness direction of size is much smaller than the other
two
dimensions,
temperature
and
other
physical
quantities in
the thickness direction of the change is very large, if the use of
a simple finite element and finite difference method will cause

of

finite element method, the thickness direction by using finite

method,
were
established
and

Numerical analysis and artificial intelligence technology
Optimization

concerns,
the traditional CAE software while in computer simulation of
a
designated
under
the
conditions
of
the
injection
molding
conditions,
but
is
unable
to
automatically
optimize
the
technical parameters. Using CAE software personnel must be
set to different process conditions were multiple CAE analysis,
combined
with
practical
experience
in
the
program
were
compared between, can get satisfactory process scheme. At the
same
time,
the
parts
after
the
CAE
analysis,
the
system
will
generate
a
large
amount
of
information
about
the
project
( product, process, analyzes the results ), which often results in
a variety of data form, requiring the user to have the analysis
and understanding of the results of CAE analysis ability, so the
traditional
CAE
software
is
a
kind
of

tools,
can
provide
users
with
intuitionistic,
effective
engineering conclusion, to software users demand is too high,
the influence of CAE system in the larger scope of application
and popularization. In view of the above, HSCAE3D software
