The housing of an energy transformer’s tank has a very robust structure, due to a load caused
by 98% vacuum that can occasionally occur throughout its entire lifetime. This master’s
thesis presents the study of a transformer’s tank and its main structural elements, what is
included in optimization of the tank’s shape. The analysis of the load includes determination
of the critical values and an analytical calculation of the stress-strain state. The definition of
the cost function is the tank’s mass, which is mathematically determined using known
parameters dependent on the design variables. Using the analysis of the threshold values the
steps of optimization of the tank’s design by curving its shorter length. The thesis concludes
that the optimized tank mass can be reduced for 17,6 % in comparison to the non-optimized
one for equal load conditions.
