Digital Prototyping gives conceptual design, engineering, manufacturing, and sales and marketing departments the ability to virtually explore a complete product before it’s built. Industrial designers, manufacturers, and engineers use Digital Prototyping to design, iterate, optimize, validate, and visualize their products digitally throughout the product development process. Innovative digital prototypes can be created via CAutoD through intelligent and near-optimal iterations, meeting multiple design objectives (such as maximised output, energy efficiency, highest speed and cost-effectiveness), identifying multiple figures of merit, and reducing development gearing and time-to-market. Marketers also use Digital Prototyping to create photorealistic renderings and animations of products prior to manufacturing. Companies often adopt Digital Prototyping with the goal of improving communication between product development stakeholders, getting products to market faster, and facilitating product innovation. Digital Prototyping goes beyond simply creating product designs in 3D. It gives product development teams a way to assess the operation of moving parts, to determine whether or not the product will fail, and see how the various product components interact with subsystems—either pneumatic or electric. By simulating and validating the real-world performance of a product design digitally, manufacturers often can reduce the number of physical prototypes they need to create before a product can be manufactured, reducing the cost and time needed for physical prototyping.〔Aberdeen Group, “The Transition from 2D Drafting to 3D Modeling Benchmark Report,” September 2006, p. 6.〕 Many companies use Digital Prototyping in place of, or as a complement to, physical prototyping. Digital Prototyping changes the traditional product development cycle from design>build>test>fix to design>analyze>test>build.〔Jeff Rowe, “Virtual Reality,” Cadalyst, March 2, 2006.〕 Instead of needing to build multiple physical prototypes and then testing them to see if they’ll work, companies can conduct testing digitally throughout the process by using Digital Prototyping, reducing the number of physical prototypes needed to validate the design. Studies show that by using Digital Prototyping to catch design problems up front, manufacturers experience fewer change orders downstream.〔Aberdeen Group, “The Transition from 2D Drafting to 3D Modeling Benchmark Report,” September 2006, p. 7.〕 Because the geometry in digital prototypes is highly accurate, companies can check interferences to avoid assembly issues that generate change orders in the testing and manufacturing phases of development.〔Aberdeen Group, “Complementary Digital and Physical Prototyping Strategies: Avoiding the Product Development Crunch,” February 2008, p. 11.〕 Companies can also perform simulations in early stages of the product development cycle, so they avoid failure modes during testing or manufacturing phases. With a Digital Prototyping approach, companies can digitally test a broader range of their product’s performance.〔 They can also test design iterations quickly to assess whether they’re over- or under-designing components. Research from the Aberdeen Group shows that manufacturers that use Digital Prototyping build half the number of physical prototypes as the average manufacturer, get to market 58 days faster than average, and experience 48 percent lower prototyping costs.〔Aberdeen Group, “The Transition from 2D Drafting to 3D Modeling Benchmark Report,” September 2006.〕 ==History of Digital Prototyping== The concept of Digital Prototyping has been around for over a decade, particularly since software companies such as Autodesk, PTC, Siemens PLM (formerly UGS), and Dassault began offering computer-aided design (CAD) software capable of creating accurate 3D models. It may even be argued that the product lifecycle management (PLM) approach was the harbinger of Digital Prototyping. PLM is an integrated, information-driven approach to a product’s lifecycle, from development to disposal.〔John Teresko, “The PLM Revolution,” ''IndustryWeek'', February 1, 2004.〕 A major aspect of PLM is coordinating and managing product data among all software, suppliers, and team members involved in the product’s lifecycle. Companies use a collection of software tools and methods to integrate people, data, and processes to support singular steps in the product’s lifecycle or to manage the product’s lifecycle from beginning to end. PLM often includes product visualization to facilitate collaboration and understanding among the internal and external teams that participate in some aspect of a product’s lifecycle. While the concept of Digital Prototyping has been a longstanding goal for manufacturing companies for some time, it’s only recently that Digital Prototyping has become a reality for small-to-midsize manufacturers that cannot afford to implement complex and expensive PLM solutions. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Digital prototyping」の詳細全文を読む スポンサード リンク
