Abstract Rapid prototyping is becoming a key factor in speeding up the product development process. This paper presents a concept of electronic prototyping called virtual prototyping. The idea is to integrate product modelling with computer simulation, realistic visualization and virtual reality techniques to make the product data model a virtual prototype. In contrast to physical prototypes, a virtual prototype is made very fast, can be manipulated and modified directly and the data is reusable. A preliminary implementation of our concept is available at IGD.

Abstract With the introduction of virtual prototyping into the product development process, simultaneous product/process design is enabled. The research reported in this paper illustrates an integration of product and disassembly process design via virtual prototyping. In this context, a virtual prototype is an information model consisting of a product model and one or more process models. Virtual prototype generation is a hybrid process consisting of both automated and interactive tasks. Simultaneous product/process design is accomplished by formulating the integrated product/process design problem as a multiobjective optimization problem in which product/process requirements are evaluated via virtual prototyping. Solution of the integrated product/process design problems is achieved through the application of the MORPS algorithm. Application of the use of virtual prototypes is presented in the simultaneous product/process design of an automotive center console.

And Function

Virtual prototyping technology as a key technology for agile manufacturing can deal with multidisciplinary knowledge across different fields. In the complex product development process, the exchange between heterogeneous data in heterogeneous environment is a universal problem encountered, which increases the complexity of collaborative parallel design of virtual prototype. Taking the product models as carriers and the different function requirements as clues, the knowledge structure and expression of product information in various fields was studied. By adopting component object model technology, direct geometry access technology, behavioural modeling technology and parametric design thinking, the interaction among tools in various function units was realized, and the effective integration of information and function in multi-fields was accomplished, the parameter-driven virtual prototype architecture of complex product based on the integration of information and function was created. The feasibility of this architecture has been verified by the actual engineering. This plan provides an effective way to carry out virtual prototype projects for enterprise.

One of the most recent techniques used by manufacturing companies to improve the product development process is computer simulation. Numerical simulation is an effective method for predicting formability of metals, and the use of computer simulation enables a significant increase in the number of tool designs that can be tested before hard tools are manufactured. Based on dynamic explicit finite element software, finite element simulation of sheet metal forming was performed to investigate the applicability of applying hydrostatic pressure on blank in multi point discrete dies. Simulation results show that using the hydrostatic pressure on blank is apposite for the process of multi point discrete dies.

Purpose A novel development process aims at finding solutions for lightweight stiffened shell structures and their efficient production. To respect the strong interdependency of structural design and production planning, particularly observed for composite structures, it is of high interest to start considering production effects in early development phases. This integrated approach requires an integrated representation of structure and production. The purpose of this study is to investigate the scope of relevant data and to find a structure for its representation. Design/methodology/approach The development task is analyzed and a system of so-called solution dimensions is presented, which covers all important aspects of stiffened shell structures and their production. An integrated product data model is developed to cover all of the solution dimensions. Findings The product data model consists of five coherent partial models. It is explained how these models are defined and how they are connected to each other. An academic example of an aircraft fuselage panel is used to demonstrate the definition process. It is shown how even complex structural concepts are defined systematically. Practical implications It is explained how this integrated product data model is used in a software project for the development of aircraft fuselage structures. Originality/value The presented approach for the definition and representation of stiffened shell structures enables the developer, e.g. of aircraft fuselage, to respect the crucial criterion of manufacturability from early development phases on. Further, new design approaches, e.g. as inspired by topology optimization, can be considered.

The paper presents advantages and disadvantages of CAD and BIM technology in the engineering environment. Specific attributes of these technologies have been compared to gain the sense of what they represent in the design and planning process. Through the practical design of the project of the cogeneration plant block, it was noted that CAD environment is more acceptable in the detailed design process. On the other hand, BIM environment, compared to CAD, is less flexible in the process of detailed design but provides a more complete data model at the level of the entire product development process.
