- Work collaboration is today normal practice in developing modern products. Engineering collaborative work involve a number of team members that need to share and exchange design ideas working with engineering analysis tools, such as mechanical computer aided engineering systems. This work presents a data mediation approach, using active database technology, which enables exchange of engineering information among distributed team members in a timely manner. The distributed data is automatically synchronised between different places using a database management system that support event-condition-action (ECA) database rules. Only the updates introduced at one location are distributed to the other locations, minimizing the information transfer and enhancing the performance. Members working at different locations can therefore interactively manipulate the same set of information at the same time

- Computer-based tools and methods have become important means of design, simulation and manufacturing in the product development process. Today, many companies function as global enterprises where practically all work is distributed and coordinated worldwide. Consequently large amounts of heterogeneous and distributed engineering data are produced. Furthermore, Computer-based analysis activities within different analysis domains normally need to combine, exchange, and share relevant product data to each other. Product development thus requires product information to be communicated between computer-based tools in such a globally distributed and heterogeneous computing environment. This paper presents how modem database technology can be used to facilitate the integration of product data, specifically information concerning multibody system (MBS) analysis. Through the examples provided, this paper shows how to use multi-database facilities to integrate MBS data between different engineering analysis tools through network; How to access MBS data by using a CORBA-based client-server model. Furthermore, it shows how to use database query language to pose queries to retrieve MBS information that is stored in the embedded database.

A system for information management in simulation of manufacturing processes
- 2002
-
In: Proceedings of the Third International Conference on Engineering Computational Technology. - Stirling : Civil-Comp Press. - 0948749849 ; , s. 131-132

Conference paper (peer-reviewed)abstract
- The usage of virtual prototyping has had great impact on the product development process during the last decade. It has evolved from mainly being applied to high-priced and low series products to include advanced analyses on everyday products This includes analysis of many of the processes that are performed in manufacturing of a product, such as cutting, welding and heat treatment. The focus of this project is to support the use of simulation tools for the manufacturing process with efficient information management. A system is being developed using database technology were it is possible to handle information prepared for and generated by simulation of analysis models for various types of manufacturing processes

A system for information management in simulation of manufacturing processes
- 2004

Journal article (peer-reviewed)abstract
- A system has been developed to manage simulation information of manufacturing processes, such as mesh information, boundary conditions and process parameters. The goal is to enable information sharing and exchange to make it possible to simulate a whole chain of manufacturing processes, and thereby predict how a modification in one manufacturing process affects the characteristics of the final product. The system has been used to predict successful simulation of a cutting process using mesh information and process parameters. An object-relational database management system is embedded in the system that uses a conceptual EXPRESS schema as database schema. The database management system is lightweight main-memory resident and incorporates an extensible and object-oriented query language. Uniform storage using database technology enables information manipulation independently of any specific simulation tool.

Computational database technology for component mode synthesis
- 2004
-
In: Advances in Engineering Software. - : Elsevier BV. - 0965-9978 .- 1873-5339. ; 35:10-11, s. 735-45
-
Journal article (peer-reviewed)abstract
- The present work show how object relational database management system technology can be used to support an finite element analysis process that includes component mode synthesis using the Craig–Bampton method for calculating reduced mass and stiffness matrices. A general object-oriented model for accessing matrix data independent of matrix representation is presented. The model is used to express the calculations of the reduced stiffness and mass matrices in a declarative query language and thereby letting the database decide how to execute the operations and manage the memory.
