This article studies the conditions for the occurrence of resonance phenomena in conical shells and their influence on the distribution of local stresses. The vibration characteristics of the shell under the influence of external dynamic loads, its natural frequencies, and the sharp increase in deformations and stresses in resonance cases are analyzed. In particular, the influence of changes in geometry, shell thickness, and boundary conditions on the formation of local stresses is studied. Based on the results of theoretical and numerical modeling, it was found that the resonance phenomenon has a significant impact on the strength and stability of the conical shell. The results obtained can be used to develop practical recommendations for avoiding resonance and reducing dangerous local stresses in the design of engineering structures.
