Objectives and Approach

The objective of this project is to research, analyse, demonstrate and give guidelines for software tools to be used by designers and manufacturers of large mechanical systems such as cranes, large robots and other large mechanisms (such as windmills) to secure optimum functionality, accuracy, reliability and economy in their products.

The project will establish a design and analysis tool for complex mechanical systems combining technologies such as the Finite Element Method, dynamic analysis of flexible mechanisms and control system models.

The design tool will be based on existing commercial software, and new functionality will be specified by the application partners in the project.

The simultaneous simulation and result processing by utilising the latest high performance computer technology will partly replace the traditional separate result postprocessing. This will enable the user to supervise the simulation in a multi-window graphical environment and interrupt or communicate with the simulation as it proceeds. Simulation of aspects of product behaviour will be made with a precision which has hitherto been impossible to model.

The project will extend the results of several ESPRIT projects, particularly numbers 322 (CAD*I), 1561 (SACODY), 2195 (CADEX) and 2614 (NIRO).

Standard formats and protocols (eg STEP) will be used wherever possible and the system will be open-ended for the easy exchange of modules. STEP formats will be described so that all data exchange can take place with the help of the STEP formatter.

The tool will employ parallel processing techniques, based on substructuring, and may require optimisation on supercomputers.

The project will concentrate on:

Exploitation

The proposed European simulation system will create a competing alternative in a market presently dominated by the US.

The results will be exploited by the partners within their own organisations in their daily work, and by providing commercially available software and a simulation guideline document for the engineering community in general.
