Modal analysis of the protective shell of the tank taking into account the sequential occurrence of defects in the welded seams of the wall

Technical research and development

“…But to ensure trouble-free operation of welded shell structures, it is necessary to constantly control the parameters of their stress-strain state, dynamic characteristics and the process of destruction of welds. At present, there is a tendency to develop systems for structural monitoring of structures, an important stage of which is the theoretical justification and the choice of diagnostic methods to determine the current state of structures in real operating conditions [122][123][124]. The primary task for such a substantiation is to develop a diagnostic model of the structure in order to determine the dependences of the parameters that characterize its technical condition, from many parameters of defects or damage.…”
