Background. An important task in the development of airborne radioelectronic facilities is the assessment of the resonant frequencies of the structure. The cylindrical shape of the structure is used less often than the rectangular one, moreover, in some cases it has greater rigidity. In addition, there are no engineering techniques in the literature for determining the natural vibration frequencies (EF) of cylindrical shells. The aim of this work is to develop a methodology for solving the problem of finding the minimum SCF of a freely supported circular cylindrical shell and an analytical expression for the frequency parameters of a cylinder with restrained ends is obtained.
