Dampener resource of seismic isolation absorber system of circular tanks for liquid hydrocarbons storage

摘要

The aim is to estimate fatigue resources of rubber-metal dampener, a part of the seismic isolation of spherical tanks for liquid hydrocarbons storage based on the calculation of the damage measure packages using modern finite element analysis, in particular, ANSYS. Thus performed: The calculation of the stress-strain state of the dampener during deformation. The fatigue curve of the tested dampener. Total measure of the dampener damage during operation was determined. An example of the proposed method application indicating the ability to provide the required resources of rubber-metal dampener in operation in the seismic isolation spherical tanks system is determined.
