A REQUIREMENT

Whether data is output from a test or a calculation, it is important to know how the results were obtained. In the case of tests, this information concerns knowledge of instrumentation, test parameters such as scanning speed on sine tests, specimen installation conditions during tests on a test-bed, and measurements for determination of irregular movements during a test on a vibrator. In the case of calculations, it concerns the description of the model, including boundary conditions and loads, as well as software related parameters and the methods used to produce these results. This information may be
essential for analysing a complex phenomenon, and it is precisely at this point that its
defects are perceived. Frequently, analysts want to compare the results of tests and
calculations. They then need easy-to-use tools, so that they can give their full attention to analysis of the physical phenomenon.


AN OFFER

A database:

The Dynaworks® application, which is based on an object-oriented database, is perfectly suited to efficient management of this data. In effect, Dynaworks® enables data to be organised in accordance with the user's own working methods, by defining a customized database schema. This schema identifies the objects to be manipulated and defines the relations between them. For example, a Project consists of Tests and Calculations.
The functions available enable all test and calculation results associated with a project to be found quickly.

Interfaces for importing data:

Dynaworks® offers users interfaces for importing data. Interfaces with several
acquisition systems exist, in particular an interface for use with Nicolet recorders. Dynaworks® can also import universal files. The datasets traditionally used in mechanics are supported. Dynaworks also has interfaces with simulation software applications, such as Matlab® and Nastran®. In effect, it is possible to run a Matlab® process from the Dynaworks® analysis window and then use Matlab® functions, importing and exporting data between Matlab® and Dynaworks®. The interface with Nastran® imports the finite elements model, as well as the results of calculations such as fundamental modes and responses, temporal and frequential, obtained by direct and modal solutions.

Tools for visualisation, analysis and animation of modal deformations:

When all this data is in the database, Dynaworks® offers tools for visualising responses and animating modal deformations and test responses. Whether data is from a test, a finite elements calculation by Nastran® ,or a simulation application such as Matlab®, it is analysed using the same tools in a single environment. This environment, based on an object-oriented relational database, ensures traceability, provides a secure area for data that can be shared via a network, and offers tools enabling the user to process data output from either tests or simulations, thereby reducing operational costs.
