STUDY OF OSCILLATIONS NATURAL FREQUENCIES FOR EMPTY AND FILLED WITH ENVIRONMENTALLY HAZARDOUS LIQUID CYLINDRICAL ELASTIC TANKS

Abstract

Tanks for storing oil, drinking water and chemicals usually have the cylindrical shells form. The strength determination of such tanks is the actual issue, especially under the suddenly applied loads action in order to prevent ecologically dangerous effects on the environment and prevent emergency situations. These could be seismic impacts, or shock loads due to explosions, aircraft crashes, etc. Most often, these tanks are modeled as rigid shells. But in practice, these tanks based on the elastic foundation, which helps to reduce vibrations under external influences
