ANSYS Workbench: Create Application-specific ANSYS Solutions with
this New Open Platform
In the product development process, the idea of
using enginnering simulation tools to "guide" the product design has long been
viewed as a means to improve product quality, reduce manufacturing costs, reduce
time to market, and most importantly, create innovative products. Now as the
barriers of price and performance begin to subside, attention in the market is
turning toward implementing engineering simulation into the entire product
development process. To download this complete white paper, fill out the Request

Assembly Analysis: Considering Techniques for
Accuracy
Assembly analysis is one of the most complex techniques for
accurately predicting how a multi-component structure will perform. Through the
automation of proven techniques, engineers can realize the benefits gained by
properly performing assembly analysis. However, the user needs to understand the
capabilities, limitations, and risks of performing assembly analysis. This
discussion reviews the most common techniques used by computer-aided engineering
software developers. Before investing in software to perform real-world assembly
analysis, take a look at the company that develops the underlying technology.
Are they known for their nonlinear analysis capabilities? Can they take
multiphysical effects into consideration at once? Do they have clients that have
used their software successfully to solve real-world assembly analysis problems?
Before you start spending your money and (more importantly) your time on
assembly analysis software, take the time to ask the experts. Consult with your
company's professional analyst or contact a local engineering analysis
consulting firm. With DesignSpace from ANSYS, Inc., you can treat components
independently, meshing each only to the level of detail your analysis requires.
Enterprise-wide Solutions: Product Design, Analysis and Management
Through Engineering Teamwork
A new class of enterprise-wide engineering
analysis software allows design engineers to perform finite-element analysis
(FEA) more routinely throughout product development, and also streamlines the
process in which dedicated analysts handle advanced studies. In this way,
analysis can be seamlessly integrated into a continuous design process, rather
than interjected as a point solution for isolated problems. Using these tools,
an engineer developing parts on a computer-aided design (CAD) system can easily
check the design at any time to gain insight into product behavior and perform
窶忤hat-if?窶・simulations to explore options and arrive at a superior design
early. Moreover, Web-enabled reporting functions allow engineers to quickly
transfer project information throughout the organization. And links to dedicated
analysts facilitate more efficient detailed analysis when needed.
Process Compression: Technologies and Strategies for Faster
Product Development
Numerous factors contribute to the success of a
manufacturer and the products it produces. Time to market, efficiency of
operation, product quality, engineering innovation, and market-driven designs,
among others. The linchpin holding all these elements together is the product
development process, from the early conceptual stages of design through release
to manufacturing and beyond, with engineering activities often devoted to
retrofits, upgrades, and other engineering changes throughout the entire product
lifecycle. Product development certainly isn't the only function of significant
importance in the manufacturing enterprise, of course. Activities in marketing,
sales, procurement, production, testing, field service and many other areas are
critical to success in the market. Indeed, input and feedback from all these
groups plays a huge role in current team-based product development initiatives.
And it is in product development, especially in the earliest stages of the
cycle, where some of the most important decisions will be made with the greatest
impact on the product窶冱 cost, performance, manufacturability and
marketability.
Leveraging the Design Chain
In the product development
process at most mid-sized and large companies, designs are defined in an
engineering department and passed along in serial fashion (i.e., a??thrown over
the walla??) to other design chain groups, each with an important perspective
and insight into how the product should be configured. Manufacturing may find a
faster, less costly way to fasten a housing to a frame, for example. Or
marketing might want a more ergonomically contoured handle. Any suggested
improvements or problems along the way send the design back to engineering.
Bringing Simulation to Surgery: Improving The Success Rate of Hip
Replacements
Joint replacement surgery is one of the most successful
procedures in medicine because it can relieve pain and permit patients to return
to productive lifestyles. However, there are times when joint replacements need
to be redone because of loosening or wear. One way to enhance the conventional
joint replacement process is to evaluate the effects of an operation prior to
surgery. What is the correct type of implant for this patient? Where, precisely,
should it be placed? How should it be installed and secured? Surgeons currently
cannot address these issues except by trial and error and clinical experience,
which can take years to develop. Yet their decisions may determine the success
or failure of these operations.
Analysis in Action: The Value of Early Analysis
One of the
driving forces in manufacturing companies is the continuing demand for reduction
in product development time and cost to maintain profitability and
competitiveness. Over the years, this requirement has prompted organizations in
a wide range of industries to find different ways to make product development
more efficient. Advancements in the entire spectrum of computer-aided design,
manufacturing, and engineering (CAD/CAM/CAE) tools in particular have automated
many design, engineering, and analysis tasks to shorten development cycles,
mostly as labor savings to minimize overhead costs.
Leveraging Simulation: The Design Innovation Process
In
todaya??s turbulent economy and brutal global markets, manufacturing companies
are doing all they can to maintain their competitive edge by developing
innovative designs. Products must stand apart from others, breaking new ground
in performance, size, shape, capacity, durability, value or other attributes
that compel consumers to select one product over another from a store shelf, or
OEMs to do business with one supplier over another. In many cases, companies use
design innovation to improve on existing products. Other times they create a
whole new class of products and dominate a market segment as competitors
scramble to catch up. Automotive industry analysts note that Chrysler, for
example, came out with the first minivan in 1983 and has never lost its market
lead since introducing this innovative vehicle class. In a world economy of
radical change, product innovation has emerged as a key market differentiator
across nearly all manufacturing industries and market sectors including
automotive, aerospace, telecommunications, industrial machines, business
equipment, discrete parts, and consumer products.
Mechanical Design Synthesis: New Processes for Innovative Product
Development
Despite the best efforts at many manufacturing companies,
some new products a?“ and ones that are redesigned a?“ flop in the market, often
totally missing what customers want, need or are willing to pay for. Some
industry observers estimate that 35% to 50% of newly launched products miss
their target markets. Such lack of success, even in a single product line, can
have a huge negative impact on corporate profits, and in some cases, can
threaten the survival of companies desperately trying to hang on in the face of
fierce competition.
Putting Analysis to Work: Multiphysics Tools for MEMS
One
of the hottest technology growth areas is microelectromechanical systems (MEMS),
which also is called micromachines and microsystems in Asia and Europe. Made
with semiconductor construction techniques, these devices have tiny parts
measured in microns (millionths of a meter) and are frequently combined with
integrated circuits on a single chip to provide built-in intelligence and signal
processing. These small, intricate devices must perform accurately and reliably,
often in the hostile environments of vehicles and industrial machines. As a
result, engineers developing MEMS must rely on finite element analysis (FEA)
software to study these microstructures in determining stress, deformation,
resonance, temperature distribution, electromagnetic interference, and
electrical properties. Leading organizations which use FEA technology in the
development of MEMS devices include Analog Devices Inc. (Norwood, MA), Lucas
NovaSensor (Fremont, CA), and the engineering consulting firm, Colibri Pro
Development AB (Stockholm, Sweden). Extensive research activities also are
underway at educational institutions around the world such as the Technical
University of Berlina??s Microsensor and Actuator Technology Center (Berlin,
Germany).
Analysis in Action: Reducing Time to Market in Electronic
Packaging
Companies getting products to market faster than others
generally capture greater market share. Time-to-market is especially critical in
the highly competitive electronics and semiconductor market, where product
designs, pricing, and distribution strategies see some of the most rapid and
revolutionary changes of any manufacturing industry. As a major player in this
market, Motorola initiated a corporate-wide cycle-time reduction program in 1992
to address these time-to-market issues. The ambitious goal of the initiative is
to reduce cycle times ten-fold by 1997 by refining the product development
process, working collaboratively in project teams, and harnessing the latest
technology. The initiative has been implemented successfully throughout
Motorolaa??s Semiconductor Product Sector, which manufactures over 40,000
products ranging from components supporting pagers and cellular telephones to
discrete consumer and automotive applications. As part of this business, the
Hybrid Power Modules Operation in Phoenix, Arizona, designs and manufactures
power modules for improving electric motor operating efficiency in numerous
industrial applications, commercial products, and electric vehicles.
