The spectrum of the natural frequencies of the triangular plates with the holes, the material of such is aluminum, and the systems of conjugated multilayer shells of revolution, which can be as calculated schemes in the design of hulls in typical rocket of space technology, is obtained. A comparative analysis of the results obtained on the basis of numerical and experimental approaches was carried out. On the basis of the conducted researches the analysis of regularities of deformation of the considered mechanical objects depending on features of their geometrical form, constructive and structural inhomogeneity, physical and mechanical properties of material, acting loads, etc. is carried out.
