Abstract

The finite element method and by using computer mathematical apparatus ANSYS defined numerical value change of air pressure in the central part of bellows according to the displacement and the occurrence of stress. These results are important in determining application of boundary conditions for the bellows and pneumatic patch accidental impacts on depressurising tank and piping, which are corrosive fluids under pressure.
