Quantitative Treatment and Testing of Rotational Degrees of Freedom

Objective



Objectives and content
The basic research project QUATTRO aims at solving the
critical issues which today prohibit the consistent use
of rotational degree of freedom (RDOF) information
(moments, angular displacements) in test-based and hybrid
(test-numerical) structural dynamics modelling. By
neglecting them, as it is the current practice, CAE
techniques such as substructuring, FEM updating and load
analysis, which are in use in many industrial sectors
(automotive, components, household, production,...) often
fail to yield the expected results, leading to suboptimal
designs or even product failures.
Therefore, the following activities will be realised:
to systematically analyse and quantify the errors in
structural dynamics analysis due to neglecting RDOFS.
to critically assess the accuracy and applicability
limits of available RDOF techniques which are inadequate
for the targeted applications.
to develop and evaluate novel methods for exciting,
measuring and modelling RDOF data with the required
accuracy.
to develop and publish guidelines to the use and the
measurement of RDOF data in the CAE process.
Furthermore, the realised findings will be evaluated in
a number of "typical" industrially relevant applications
and a round-robin test will be performed.
The outcome will hence not only consist of feasible and
enhanced techniques and tools, but also a recommended
"best practice" for the whole of the European industry
will be realised.
The partnership to realise these objectives consists of 4
universities, leading the research in this field through
complementary technologies, and two industrial companies
(one end-user: a manufacturer of a variety of components
and products and one IT-SME commercialising advanced CAE
tools). Together they combine the required methodology,
application and analysis know-how.

Fields of science (EuroSciVoc)

CORDIS classifies projects with EuroSciVoc, a multilingual taxonomy of fields of science, through a semi-automatic process based on NLP techniques. See: The European Science Vocabulary.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Call for proposal

Procedure for inviting applicants to submit project proposals, with the aim of receiving EU funding.
