Burning
Rubber to Get Wheels Made
|
Wheel maker American Racing Equipment Inc. of
Rancho Dominguez, Calif., will implement product planning technology to
help meet the company's aggressive 2003 product introduction schedule,
said Andy Paskin, director of product engineering at the company. The
aftermarket wheel manufacturer offers more than 100 alloy wheel styles.
The new software application, called ActiveProduct, will link everyone
involved with product design and engineering.
Another software module, called ActiveProject, will allow tooling and
mold suppliers to become involved in the design process at an earlier
stage than they could previously, which helps them know about and anticipate
design changes, Paskin said.
With the software, users can track the activities of design team members
and make sure the members have access to the most up-to-date information
about design changes.
The technology is manufactured by Framework Technologies of Burlington,
Mass.

Plant Design Software To Grow This Year
|
Plant design software and services will grow by
7 percent, to more than $479 million this year, according to the market
research and analysis firm Daratech of Cambridge, Mass.
Despite a global recession and economic and political uncertainties, process
and power plant operators are stepping up their investments in information
technology. The aim: to help cut costs and head counts by using the plant
design software to wring inefficiencies from power projects. The software
also helps power operators collaborate with suppliers and customers and
secure technology infrastructures, the research firm said.
Driving these new levels of investment are the pressures on top management
to reduce the cost of production assets and control project risks, all
in a shorter project-execution time frame, according to the research firm.
With revamps of existing systems making up the bulk of today's
contracts in the process industries, the need for power operators to use
software models for accurate costing, scheduling, procurement, and on-time
delivery is spurring investment in laser scanning and in technology for
coordinating and integrating the resulting data with three-dimensional
design models from the project phase, the firm said.

NIST
Brings Quantum Computers Closer
|
Scientists at the National Institute of Standards
and Technology in Gaithersburg, Md., say they've developed a way
to increase control of the quantum bits, or qubits, that may some day
store and process data using the principles of quantum mechanics.
Qubits represent information as ones and zeros as digital bits do in today's
computers. The NIST team demonstrated a way to precisely control a computational
operation, which they call a logic gate. They can control the operation
between two qubits 97 percent of the time, compared to just 80 percent
with previous techniques. With further improvements in logic gate reliability,
universal computation on a large scale should be possible, the scientists
say.
The scientists used ions, or charged atoms, as qubits, for their experiment.
To increase control of quantum bits, the NIST scientists used lasers to
manipulate beryllium ions trapped in a vacuum; they spin up or down to
represent one or zero. The quirks of quantum mechanics allow ions to exist
in blends of the two spin states and also to become entangled so that
the properties of two ions are intertwined. Qubits, therefore, are able
to represent multiple values simultaneously and to link values in logical
ways.
It is the qubits' capability to be intertwined that would allow
a quantum computer to perform tasks like factoring very large numbers
that are impossible with today's technology. The NIST experiments
focused on manipulating qubits to control their entanglement and thus
the computation process.

Renault Formula One Team Uses CAD
|
The Renault Formula One Team of Enstone, England,
recently installed CAD software specifically geared for composite design
and manufacturing to help design the composite parts used on its race
cars.
 |
| The Renault Formula One Team uses a CAD application,
called FiberSim, to help design race car parts that are made of composite
materials. |
Because composite materials are strong and lightweight, many Formula
One race car designers use them for the monocoque, nosebox, panels, rear
wing, and other areas of the vehicle. But weaknesses can be introduced
into the parts when they're manually assembled, said Alan Duerden,
CAD support engineer for the Renault team.
Also, the parts must meet stress and load conditions mandated by the Federation
Internationale de l'Automobile of Paris, a world motor sport governing
body. The CAD software, called FiberSim from Vistagy Inc. of Waltham,
Mass., helps engineers ensure that the parts they design are strong enough
to withstand shifts during assembly and to meet the federation's
standards, Duerden said. The software allows engineers to test for strength
as they design.

Chrysler Goes With Fatigue Analysis
|
The Chrysler Group of Auburn Hills, Mich., has
implemented new fatigue software that identifies and prioritizes potential
automobile durability issues and predicts the life of components and structures
used within a vehicle. The Chrysler Group is the North American-based
business unit of DaimlerChryler AG.
The software, Fe-Fatigue, from nCode of Southfield, Mich., helps visually
point Chrysler engineers to part areas that might fail due to fatigue.
The information is then delivered to the automaker's physical testing
and virtual prototyping groups so they can make necessary changes in part
design.
The software includes features for fatigue analysis of spot and seam welds,
vibration-induced fatigue, and temperature corrections for applications
such as engine components.

Seeing Oil Inside a Rock
|
Brazilian oil supplier Petrobras is using medical
X-ray technology and visualization software to model oil flow inside the
porous rocks of petroleum reservoirs to ensure that oil fields aren't
abandoned before oil is fully tapped. Oil fields are sometimes abandoned
even though as much as 70 percent of the oil remains, according to Petrobras.
Contrary to the image of the oil geyser, most oil doesn't sit underground
in big pools. The source is usually within rocks or sandy soil. The trick
is in getting it out of the ground. Most oil recovery involves pumping
chemical-infused water into the ground to force oil out of the rocks.
But this method extracts only about 30 percent of the oil inside a rock.
 |
| Engineers at Brazilian oil supplier
Petrobras use medical X-ray techniques and visualization software
to get an idea of the oil remaining inside porous rocks before abandoning
oil fields. |
The rocks from which oil is extracted are like tricky sponges, according
to Petrobras engineers. Traditionally, engineers determined rock permeability
and porosity with a procedure that measures how much water is injected
and how much oil gets out under specific conditions of temperature and
pressure.
They now use medical tomography equipmentsimilar to that used
to X-ray human bonesto scan a rock sample that's been injected
with water. They then construct a 3-D model of the rock from the scans
and use computer simulations to numerically characterize the properties
inside.
The computer simulation data is then loaded into visualization software
called EnSight from Computational Engineering International of Apex, N.C.,
which generates 3-D animations that show fluid behavior inside the rock.
The visualization software gives Petrobras engineers a visual analysis
of the permeability and porous properties inside the rock sample. They
also use the software to share findings with other members of the team
who can easily see and understand what's happening inside the rock.

Data Acquisition Links GM Test Stations
|
To tie several discrete testing stations into
one data analysis environment, General Motors Powertrain, a manufacturer
of engines, transmissions, castings, and components for General Motors,
has standardized on one data analysis system.
Linking the isolated testing stations via one system lets engineers evaluate
test data from laboratories around the world, which saves engineering
hours and cuts costs, according to the engine maker. GM Powertrain engineers
use the Technical Test Data Environment from Quantum Controls of Detroit
for the data analysis environment. Quantum Controls is partnered with
data analysis software and hardware provider National Instruments of Austin,
Texas, which provides the Diadem software used in the Quantum hardware.
With the software, engineers view standard reports and conduct data analysis
tasks that show the results of tests for temperatures, pressures, revolutions
per minute, fuel efficiency, and emissions.
Previously, GM Powertrain engineers couldn't benefit from the work
produced in multiple laboratories because of incompatible data formats
and the fact that local data storage software applications weren't
compatible. With the new system, engineers can access and analyze data
from any location, according to the powertrain company.
The software converts the product-specific names into universal names
and converts data into standard international units. Engineers use this
acquired data to generate graphs and create portable document format file
reports that can be stored on a server for access via the Internet.

Reading CAD Files In FEA Applica-
tions
|
Dana Corp.'s commercial vehicles systems
group in Kalamazoo, Mich., makes and tests bus and motor home steering
axles, drive axles, suspensions, brakes, and other components for the
vehicle's original equipment manufacturers. The company recently
purchased CAD model repair software that ensures CAD files passed back
and forth between systems are complete and uncorrupted.
The software, called CADfix, from ITI TranscenData of Milford, Ohio, helps
improve data exchange between Dana Corp.'s CAD and finite element
analysis systems. The company uses CAD software from PTC of Waltham, Mass.,
and analysis software from Ansys of Canonsburg, Pa.
"In order to avoid file corruption between systems, we were having
to defeature CAD models to such an extent that the FEA results lacked
an adequate level of accuracy," said Prasad Mangalaramanan, the
lead computer-aided engineering specialist at the Dana Corp. division.
Often, engineers must decrease the number of features included in a CAD
file before that file can be adequately read by FEA software. The Dana
Corp. division formerly used the neutral file-sharing initial graphics
exchange specification, or IGES, format that allowed CAD files to be more
easily passed to FEA software. But even using the neutral format, many
features on complex CAD files couldn't be transmitted into the
FEA software.
"We needed a way to mesh complex CAD components without spending
too much time in defeaturing, to retain as much of the original geometry
as possible, and to improve the accuracy of our FEA analysis,"
Mangalaramanan said.
The new CAD model repair software meets the division's needs, he
added.

Music Systems Maker Cuts Prototype Time
|
Executives at Bang & Olufsen in Struer, Denmark,
a maker of music systems, televisions, loudspeakers, and telephones, recently
announced a new business strategy: more new products and shorter time
to market.
Though the strategy mirrors the quick pace of product development in today's
speeded-up marketplace, it meant that engineers at the company had to
find a way of reducing the number of prototypes needed before the final
product met approval. To help with that goal, the company implemented
a new CAD system that allowed engineers to design a product, analyze results,
and make changes to the digital design before producing an actual prototype.
 |
| Bang & Olufsen of Denmark, which
makes stereos and telephones, uses CAD software from PTC to track
design modifications and to design products like the BeoLab 2 subwoofer.
|
Bjarne Frandsen, a technology specialist at Bang & Olufsen, helped
to implement the new design software, Pro/Engineer, from PTC of Waltham,
Mass. The CAD software ensures that all modifications are tracked within
the system, he said.
"Even though we work in groups where every individual member is
kept constantly up to date on what the other team members are doing on
specific products, it's important that we can always be sure the
latest version of the latest modification appears on everyone's
screen," Frandsen said. "This applies in particular to those
projects that involve teams whose members work in different parts of the
world."
Design ideas introduced at brainstorming sessions are now often simulated
and tested within the CAD software to ensure their viability before a
design continues or becomes more specific, he added. Engineers have used
the new software to design the company's BeoLab 2 subwoofer and
the BeoVision 3 wide-screen television, he added.
