Title: |
Modelling procedures of engineering structures in terms of data
management and optimisation for structural analyses using the finite
element method
|
|
|
Abstract: |
The present
work demonstrates a creation methodology of the virtual prototype, a
common task in the field of Finite Element Analysis (FEA) and
Computer Aided Engineering (CAE). Highest priority has been given in
the design of the appropriate routines and tools that target to
both, high quality modelling data management and introduction of
automation in the structural analysis of models derived from complex
engineering structures. More specifically, the tools that have been
developed and are suggested to work in conjunction with a
pre-processor will introduce a whole new classification of the
required processes belonging to the virtual prototype development.
The ultimate target has been the creation of the Common Geometrical
Model that will act as the basis and starting point for the creation
of all Common Models in every structural analysis task.
Additionally, the need of common mesh management and minimisation of
time spent on repeating common tasks is fully satisfied by the
suggested Mesh Management Utility. All the aforementioned advances
are accompanied by an organised and well-structured way of storing
the modelling data in a central Product Data Management system
(PDM). The latter is a modelling data comparison tool as well as a
tool responsible for the automated substitution of all
sub-structures in an existing model. As a result, the virtual
prototype developing - creation time is reduced dramatically,
leaving the developers - engineers with available time to focus on
the behaviour of the examined structure under all desired structural
analyses |
