Ă propos de ce livre
Product Design Modeling using CAD/CAE is the third part of a four-part series. It is the first book to integrate discussion of computer design tools throughout the design process. Through this book, you will:
- Understand basic design principles and all digital design paradigms
- Understand computer-aided design, engineering, and manufacturing (CAD/CAE/CAM) tools available for various design-related tasks
- Understand how to put an integrated system together to conduct all-digital design (ADD)
- Provides a comprehensive and thorough coverage of essential elements for product modeling using the virtual engineering paradigm
- Covers CAD/CAE in product design, including solid modeling, mechanical assembly, parameterization, product data management, and data exchange in CAD
- Case studies and tutorial examples at the end of each chapter provide hands-on practice in implementing off-the-shelf computer design tools
- Provides two projects showing the use of Pro/ENGINEER and SolidWorks to implement concepts discussed in the book

Introduction to e-Design
Abstract
The e-Design paradigm employs IT-enabled technology, including virtual prototyping, early in product development to support cross-functional analysis of performance, reliability, and costs, as well as quantitative trade-offs in decision making. Physical prototypes of the product design are then produced using rapid prototyping and computer numerical control. e-Design has the potential to shorten overall product development, improve product quality, and reduce product costs (1) by bringing together product performance, quality, and cost early in the design phase; (2) by supporting design decision making based on quantitative product performance data; and (3) by incorporating physical prototyping to support design verification and functional prototyping. This chapter introduces the e-Design paradigm and the components it comprises, including knowledge-based engineering and virtual and physical prototyping. Designs of a simple airplane engine and a high-mobility multipurpose wheeled vehicle are offered as illustrations.

Conventional product development employs a design-build-test philosophy. The sequentially executed development process often results in prolonged lead times and elevated product costs. The proposed e-Design paradigm employs IT-enabled technology for product design, including virtual prototyping (VP) to support a cross-functional team in analyzing product performance, reliability, and manufacturing costs early in product development, and in making quantitative trade-offs for design decision making. Physical prototypes of the product design are then produced using the rapid prototyping (RP) technique and computer numerical control (CNC) to support design verification and functional prototyping, respectively.
e-Design holds potential for shortening the overall product development cycle, improving product quality, and reducing product costs. It offers three concepts and methods for product development:
âą Bringing product performance, quality, and manufacturing costs together early in design for consideration.
âą Supporting design decision making based on quantitative product performance data.
âą Incorporating physical prototyping techniques to support design verification and functional prototyping.
1.1. Introduction
A conventional product development process that is usually conducted sequentially suffers the problem of the design paradox (Ullman 1992). This refers to the dichotomy or mismatch between the design engineer's knowledge about the product and the number of decisions to be made (flexibility) throughout the product development cycle (see Figure 1.1). Major design decisions are usually made in the early design stage when the product is not very well understood. Consequently, engineering cha...
