Method for obtaining vibrating performance of oil and gas field liquid storage pot structure

Abstract

The invention provides a method for obtaining the vibrating performance of an oil and gas field liquid storage pot structure. According to the method, a vibration table substructure experiment method is used for studying the oil and gas field liquid storage pot structure, a pot body part of a liquid storage pot serves as an experiment substructure for conducting an experiment, a basic part of the liquid storage pot serves as a numerical value substructure to complete the experiment in a computer, and therefore the influences on the size in a traditional technology are avoided. Compared with the prior art, the method can reflect the vibrating performance of the prototype structure of the liquid storage pot more accurately.

Description

technical field [0001] The invention relates to the technical field of vibration performance research of liquid storage tanks in oil and gas fields, in particular to a method for obtaining the structural vibration performance of liquid storage tanks in oil and gas fields. Background technique [0002] The shaking table experiment refers to the experiment carried out on the object or model under vibration to evaluate the anti-vibration ability of the product in the expected use environment. The design of oil and gas field storage tanks also takes into account their vibration performance. At present, scholars at home and abroad usually test the seismic performance of oil and gas field liquid storage tanks through full-structure shaking table experiments, while the prototype structure of oil and gas field liquid storage tanks is usually large. The disadvantage is that the traditional shaking table experimental method can only complete the small-scale model experiment. Due to t...

Problems solved by technology

At present, scholars at home and abroad usually test the seismic performance of oil and gas field liquid storage tanks through full-structure shaking table experiments. However, the prototype structure of oil and gas field liquid storage tanks is usually relatively large. When considering the structural interaction of oil and gas field liquid storage tanks, it is limited by the size and bearing capacity Insufficient, the traditional shaking table test method can only complete the small-scale model test. Due to the size effect, the data obtained from the test cannot be applied to the prototype structure in many cases, which easily leads to the result being difficult to reflect the performance of the prototype structure.
