ANSYS software-based horizontal storage tank stress evaluation method

Abstract

The invention discloses a horizontal storage tank stress evaluation method based on ANSYS software, and belongs to the field of storage tank stress analysis and evaluation methods. On one hand, the invention determines a stress analysis method based on finite element analysis and simulation software ANSYS Workbench to carry out simulation researches such as geometric modeling, grid division, boundary condition setting and result solving on the saddle of the horizontal storage tank and an opening pipe connecting area structure so as to obtain the stress distribution of the storage tank under the condition that the storage tank bears a load. And on the other hand, linear evaluation is conducted on the maximum stress point obtained through finite element analysis, strength checking is conducted on the result by referring to the'pressure vessel analysis design standard ', and whether the storage tank can continue to serve or not is judged according to the evaluation result. The method aims to form a reasonable method for analyzing and evaluating the safety performance of the storage tank, and help is provided for formulating corresponding measures.

Description

technical field [0001] The invention relates to the field of storage tank stress analysis and assessment methods, in particular to a horizontal storage tank stress assessment method based on ANSYS software. Background technique [0002] Storage tanks are special equipment for storing liquids, chemical raw materials, and other materials. They have the characteristics of simple structure, low cost, and fewer restrictions on use. The horizontal storage tank is a kind of storage tank with high frequency of use and wide application at present, and is usually used in gas stations, oil depots and other places. [0003] At present, the research on storage tank safety technology is not comprehensive enough, and the relevant system measures are not perfect enough. The safety status of storage tanks is worrying. The reliability of storage tanks is an important engineering problem that needs to be solved. From a safety point of view, due to the particularity of the storage tank storage...

Problems solved by technology

[0003] At present, the research on storage tank safety technology is not comprehensive enough, and the relevant system measures are not perfect enough. The safety status of storage tanks is worrying. The reliability of storage tanks is an important engineering problem that needs to be solved.

From a safety point of view, due to the particularity of the storage tank storage medium, the safety performance of the storage tank must be ranked first. Once an accident occurs, it will be a catastrophic accident; from an economic point of view, once an accident occurs in the storage tank, it will bring Huge human, material and economic losses
