Abstract
The article discusses the results of experimental studies on the verification of new mathematical models of an opened thin-wall shell forced vibrations with a small attached mass and a rigidly clamped edges. Nowadays, the opened thin-wall shells are widely used in aircraft manufacturing, buildings and structures construction, in various industries. Various small masses (fuel tanks, radio equipment, air conditioners, etc.) are attached to open shells. At the same time, these structures are affected by various loads (wind, snow and vibration), which causes forced oscillations, which are composed of a shell and natural oscillations lead to resonance phenomena, in some cases, structural destruction and man-made disasters. According to the results of research, an experimental verification of the mathematical model of an open thin-walled shell forced oscillations with a small added mass and rigidly clamped edges was carried out.
