What is a Digital Mock Up (DMU)?

aircraft digital mockup

Digital mockup or DMU is a concept that allows the description of the product, usually in 3D, for the entire life cycle. Digital mockup enriched by all the activities that contribute to describe the product. The product design engineers, manufacturing engineers, and support engineers work together to create and manage the DMU.

The digital mockup allows engineers to create a virtual assembly of aircraft components.
No need anymore to test empirically the interminable use physical mockups and prototypes. The digital mockup is the only point of reference for the product in the company.

The smallest details can be visualized and take into account in the design. The digital mockup also ensures that data can not be lost, everything is stored in a single computerized repository, rather than spread among multiple images. Everything is integrated by a digital mockup, the structure is completed and the system (cables, tubes, equipment installation, etc.) defined upstream in the finest detail, which greatly facilitate programming machine tools and assembly robots. A direct link was established between design and production, which will continue to be strengthened during the following years.

One goal is to have the essential knowledge of the future or the product is supported for replacing physical prototypes with virtual, using 3D computer graphics techniques. As an extension it is also often referred to as Digital Prototyping or Virtual Prototyping. The second definition refers specifically to the production of physical prototypes, but they are part of the concept of DMU. DMU allows engineers to design and configure complex products and validate their design without ever needing to build a physical model.

Among the techniques and technologies that make this possible are: the use of lightweight 3D models with different levels of detail using data structures such as JT lightweight XVL and PDF enables engineers to visualize, analyze, and interact with large amounts of product data in real-time on standard desktop computers. Direct interface mockups for Digital and PDM systems. Active digital mockup technology that unites the ability to visualize the assembly mockup with the ability to measure, analyze, simulate, design and redesign.

CATIA V5 Tutorials Mechanism Design & Animation

The tutorials are written so as to provide a hands-on look at the process of creating an assembly, developing the assembly into a mechanism, and simulating the motion of the mechanism in accordance with some time based inputs. The processes of generating movie files and plots of the kinematic results are covered. The majority of the common joint types are covered. Students majoring in engineering/technology, designers using CATIA V5 in industry, and practicing engineers can easily follow the book and develop a sound yet practical understanding of simulating mechanisms in DMU.
