Σύνοψη

This project outlines a general procedure for modal
testing, the main purpose of which is to find the mode
shapes of vibrations of the aeroplane model and thus by
studying these deficiencies suggest improvements to the dynamics of the structure.
It was neces~ary first to study the theory behind
vibrations in structure in order to acquire more
knowledge and be able to interpret the experimental
results more thoroughly.
To obtain these mode shapes a testing had to be
conducted on a simple construction of an aeroplane
model. The testing layout involved many components
which had to be studied theoretically before applying
them in practice, and this is the purpose for including
the chapter of Mobility Measurement Techniques as well
as a brief description of the most important testing
equipment.
The results obtained from the testing were further
processed using a computer program to obtain the
required form in order to enable the drawing of the
mode shapes.
From the mode shapes acquired from the testing some
suggestions were made for improving the structure, such
as strengthening the structure to specific points where
deficiencies were detected. Moreover some suggestion on newly developed high strength materials (like Keflar,
Carbon, Titanium, Aluminium-Lithium) as well as high
performance fibers and plastics.
