Abstract

The invention discloses a strength calculation method of a heat exchanger, electronic equipment and a computer readable storage medium, a model of the heat exchanger comprises a tube bundle model and a tube plate model, the tube plate model is provided with a tube plate tube distribution area, and the tube bundle model is arranged in the tube plate tube distribution area in a penetrating mode; the method comprises the steps that based on the principle that bending rigidity and tensile rigidity are equivalent, equivalent treatment is conducted on a tube bundle model to obtain an equivalent cylinder model, and equivalent treatment is conducted on a tube plate tube distribution area to obtain an equivalent solid circular flat plate model; according to the principle that the Poisson effect is equivalent to the axial load, equivalent loads of the tube bundle model and the tube plate model are obtained; a finite element stress analysis model is established according to the equivalent cylinder model, the equivalent solid circular plate model and the equivalent load; and strength calculation is carried out on the heat exchanger according to the finite element stress analysis model. According to the scheme provided by the embodiment of the invention, the analysis difficulty can be reduced and the calculation time can be shortened under the condition of ensuring that the finite element stress analysis result is accurate.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a method for calculating the strength of a heat exchanger, electronic equipment and a computer-readable storage medium. Background technique [0002] A heat exchanger is a device that transfers heat between materials at different temperatures. It can maintain or change the working temperature and phase state of materials. It is widely used in various fields of industry and agriculture such as oil refining and chemical industry. Among them, the shell-and-tube heat exchanger is one of the most widely used and most used heat exchanger forms. [0003] Generally, the strength calculation of a shell-and-tube heat exchanger includes four parts: the tube box, the shell, the tube bundle, and the tube sheet. The national standard GB / T151-2014 and the American TEMA standard both give the design and calculation principles of heat exchangers with most engineering application paramete...
