Application of Digital Mockup Technology

Abstract. As we all known, it is a hard and risky task to use a real physical tunnel boring machine prototype in experiment for the reason that it is expensive, complex and used in an special operating environment. Based on virtual reality technology, the function simulation of digital mockup using VR system is proposed, the function simulation of full-face Tunnel Boring Machine (TBM) based on Division Mockup is finished and verified by the consistency between theoretical study and actual simulation results. This paper provides the basis for design and improvement of product in order to reduce the production costs and time-to-market.

Realistic Visualization

The integration of ergonomic simulation in Digital Mockup and Virtual Reality requires an adapted digital man model design. Virtual ANTHROPOS was developed for the needs of this technology. Beside a realistic visualization of the human being (skeleton, different bodytypes, consideration of clothing), complex animation algorithm and automatic behavior simulation are necessary. Increased ergonomic functionalities allow the fast analysis of workplaces and products. In cooperation with universities and companies Virtual ANTHROPOS was integrated in different Virtual Reality platforms and is used to analyze, design and sale cars and airplanes.

Geometric Primitives

The model of extracting a skeleton of mechanism is established from an existed three-dimensional CAD product model. Using assembly features, a recomposition of assembly information is carried out. At same time, geometric primitives are defined and classified. And according to the information, kinematic pairs are distinguished and matched. Using the given methods, a prototype system extracting and drawing a skeleton of mechanism is developed. Extracting a skeleton of mechanism from digital mockup has been realized primarily, which can deal with rotation pair, sliding pair, gear pair and multi-pair components consisting of these kinematic pairs. Finally, the paper demonstrates the feasibility of extracting a skeleton of mechanism by an application instances.

Digital Mockup

Digital mockups have become an integral part of the design of aircraft engines and their environment (nacelle, pylon). In this paper, we show that the conventional physical mockup is not a necessity any more. In fact, the experience of the CFM56-7 design shows that the adjustments required to compensate for the absence of a physical mockup have brought with them a considerable amount of flexibility and reactivity. Thus the deletion of tile physical mockup means a lot more than the corresponding direct savings it generates. Relying solely on the digital mockup is a major change in the design process, and greatly contributes to the global quality of the product.
