This paper presents an overview of actual approaches in virtual engineering, mainly from the design point of view. The evolution of the market has necessitated the reduction of time-to-market, essentially because the product life cycle is shorter, but also because it is very important to proceed more rapidly from an initial conception to a mass production object. As a result of newly evolved software DOI: environments, knowledge-based systems, and product data management, processes for integrated design and manufacturing for new products have emerged. Owing to this evolution of virtual engineering technologies, it has become possible today to validate parts representative of mass production within a very short time. This paper provides an overview of the actual methods and tools in all the components that affect the speed and efficiency of product development, in particular all the possibilities available to the designer, from the earliest stages of a product's life cycle.

Abstract In recent years increasingly pressure has been applied on aircraft component suppliers to reduce design lead-time and design cost of aircraft components. To achieve this reduction in lead-time and cost, advanced automation tools that automate part of the engineering process can be used. Knowledge based engineering (KBE) tools are one such automation tool type and automate part of the engineering process based on existing knowledge within a company. In this paper the development process and use of a KBE application to design machined ribs in an industrial setting is discussed. The development of the KBE tool has resulted in the standardisation of the design methodology. Furthermore it has reduced machined rib design lead-time in a project to develop a bussines jet empennage by 40%.

The development of control software for mechatronic systems requires data and information from all design domains in order to create the required integrated functionality. This paper proposes a method that combines function modeling and multi-domain modeling primitives to generate control software. Provided a function model based on the Function-Behavior-State modeling paradigm and performance requirements, a knowledge-based engineering application instantiates a virtual product model and control software for a target platform. Object-oriented modeling techniques provide for the development of primitive libraries, which represent both hardware and software components, while integrated design rules ensure that components are correctly placed and connected. Requirements are translated to software specific parameters. A case study of a mobile robot shows that for specific applications both target and simulation control software code can be generated from the same input, and a generated virtual product model can serve as a simulation model in order to validate functionality.

The Internet and World Wide Web (WWW) are now evolving as an important communication technology and a major information resource provider for industry. This paper discusses the development and implementation of a knowledge-based gear design and manufacturing system over the Internet to create new integrated design and manufacturing environments. By providing access to an interactive web-based support system, any designer with a WWW browser becomes a potential user of this on-line design system. Once connected, the designer follows the system instructions and submits the necessary input data on the appropriate web pages. The server receives a request from a client and invokes a CGI (Common Gateway Interface) program that processes the information provided through the user Interface. The CGI parses the data and has the ability to remotely run the knowledge-based gear design system that integrates knowledge about all aspects of gear design and manufacturing and provides powerful reasoning and decision-making capabilities for reducing the time between gear tooth creation, detailed design and manufacturing process specification via the Internet. When the execution is completed, full specifications definition, geometry, kinematic-loads and stresses are determined through Finite Element Analysis (FEA) within ANSYS, VRML models of the gear pair and gearbox assembly including gears, shafts, bearings and housing are exported according to the designer requests and sent back to designer on the web browser. To accomplish this, a combination of HTML, JavaScript, VRML, CGI Script and C++ is used. Finally, an example on spur gear design utilizing a parallel gearbox design model configuration is discussed.

<p>BAHASA INDONESIA:</p><p>Tulisan ini menunjukkan beberapa pemikiran sebagai berikut: <em>Pertama</em>, desain <em>integrated twin towers </em>dilakukan dalam rangka menyongsong perubahan IAIN menjadi UIN Sunan Ampel. Dalam desain <em>integrated twin towers </em>posisi keilmuan agama dan umum tidak dicampur menjadi satu, tetapi dibiarkan berjalan sendiri-sendiri, dan pada saat tertentu dipertemukan untuk saling berdialog. Dalam desain <em>integrated twin towers </em>keilmuan agama tidak bermaksud mengintervensi keilmuan umum, karena keilmuan umum dianggap sudah mapan, jadi biarkan berjalan secara wajar pada posisinya; yang penting di antara kedua keilmuan itu bisa saling berkomunikasi.<em> Kedua, </em>desain Islamisasi ilmu dilakukan dalam rangka mengkritisi keilmuan umum yang notabene banyak bersumber dari Barat dan bersifat sekuleristik, materialistik, dan individualistik. Dalam proses Islamisasi ilmu, keilmuan Islam berupaya mengintervensi keilmuan umum dalam rangka memfilterisasinya sehingga keilmuan tersebut menjadi Islami. Jadi Islamisasi ilmu berarti memberikan wawasan (<em>world view</em>) keislaman kedalam keilmuan umum.<em></em><em> Ketiga,</em> meskipun ada perbedaan di antara desain integrasi keimuan berbasis Islamisasi ilmu dengan <em>integrated twin towers, </em>namun juga ada persamaannya. Perbedaannya<em> </em>terletak pada proses (epistemologi)-nya. Dalam prosesnya, desain Islamisasi ilmu berusaha mengintervensi kajian keilmuan umum dengan pendekatan kajian keagamaan; sedangkan dalam desain <em>integrated twin towers </em>keilmuan agama tidak bermaksud mengintervensi kajian keilmuan umum. Persamaannya<em> </em>terletak pada kurikulum (ontologi) dan tujuan (aksiologi). Dalam hal kurikulum, keilmuan yang dikaji adalah bidang kajian keilmuan agama dan umum. Sementara dalam hal tujuan, Islamisasi ilmu dan <em>integrated twin towers </em>sama-sama bertujuan untuk mengintegrasikan keilmuan agama dan umum, mendialogkan, mengkomunikasikan, dan mensinergiskannya; sehingga menjadi keilmuan yang utuh-integral-integratif.</p><p> </p><p>ENGLISH:</p><p>This paper shows some idea as follows: First, integrated design of the Twin Towers as the changing action from IAIN to UIN Sunan Ampel. The religion and general knowledge’s position of Twin Towers’ integrated design is not mixed into one, but it works individually, and at the certain time are united in mutual dialogue. Second, Islamize design is done in order to criticize the general knowledge which has western sources and are secular, materialistic, and individualistic. In the process to Islamize the knowledge, Islamic knowledge tries to intervene the general knowledge in order to filter it so the knowledge will be Islamized. Consequently, to Islamize knowledge is to give an Islamic concept into general knowledge. Third, there are the similarities and differences between integrated design knowledge based on Islamic knowledge and integrated Twin Towers. The difference is in its epistemology process. The similarity is in the curriculum (ontology) and objective (axiology). In the curriculum, the examined knowledge is religion and general knowledge. While the objective, Islamize knowledge and integrated Twin Towers aims to integrate religion and general knowledge, to dialogue, to communicate, and to synergy, so it can be a knowledge which is intact-integral-integrative.</p><p> </p>

In structural design, the preliminary synthesis stage derives judgmental knowledge from engineering heuristic and experience which are usually expressed in symbolic form. On the other hand, detailed design involves extensive numerical processing. An integrated computer-aided design system should be able to handle both symbolic and numerical processings. It must also be able to integrate engineering databases and CAD packages within a single environment. The knowledge-based system approach provides a venue for achieving all these requirements. This paper presents a prototype knowledge-based system for lattice design that can perform several essential tasks including preliminary synthesis, numerical model generation, nonlinear finite element analysis, code compliance checking and member sizing. The system user is guided throughout the design session by interactive graphical user interfaces which facilitate the design process.
