Dynamic modification of structures involves the transformation of an existing model in the
new one, which has better behavior and higher accuracy in comparison with the existing. The
main objective of a dynamic modification of the construction is to increase the first natural
frequency, and that the gap between adjacent frequencies is as big as possible. This paper focuses
on the improvement of dynamic characteristics of a tubular collector in one substation. It is
shown how change of boundary conditions and the geometry of the cross section can improve
dynamic characteristics of the structure. In this analysis the finite element method is used for
calculating the natural frequencies, potential and kinetic energy in each node. In the particular
case of a tube collector is confirmed once again, what was well known, that the change in the way
of support (boundary conditions) is the most efficient way of dynamic modification. Additionally
is shown one way to increase the dynamic... stiffness while reducing the weight of the whole
structure by choosing the right cross-section.
