Title: |
Developing methodologies for morphing constructions analysis models
and optimizing them after the morphing process
|
|
|
Abstract: |
The goal of
this dissertation is to examine the implementation of morphing, as
it is known in the world of computer graphics, in mechanical
constructions models that are built with finite elements. Τhis idea
came up from the analysts engineers' need, for a tool that will
allow them to apply modifications directly into the finite elements
mesh, in order to improve the geometry of their models, thus
minimizing the need to use drawing data. Most known morphing
methodologies were developed and applied, based on this framework,
while a great deal of organization and functionality problems of
this process, were conformed. Emphasis was given in morphing
complicated structures, like those of car bodies. Solutions that
reassure the re-usability of this process as well as the utilization
of its parametric possibilities were introduced and the cooperation
with an optimization system was achieved. Finally, a significant
part of this dissertation was devoted in the development of an
automated method to improve and correct the morphed mesh quality.
This stage is essential for the creation of good and solvable
models, while a necessary requirement is the recognition and the
preservation of the most important model features. The use of
morphing as a modification tool, inside a preprocessing system, can
reduce the optimization time of a virtual prototype and
significantly speed up the developing cycle of a structure |
