Steam load loading method, system and equipment for finite element simulation and medium

Abstract

The invention discloses a steam load loading method, system and device for finite element simulation and a medium. The method comprises the steps: determining the temperature distribution information of the center point of each unit in a concrete model, and calculating the steam pressure distribution information of each unit in the concrete model; converting the steam pressure distribution information into three-way principal stress of a corresponding unit, writing the three-way principal stress into a blank result file to obtain a steam pressure stress field result file, and importing the steam pressure stress field result file into the concrete model to obtain a static balance analysis result; extracting a node force result of each unit in the concrete model; establishing a node set of the concrete model, and correspondingly applying a node force result to each node of the concrete model as a load. According to the method, the temperature field of the concrete model is converted into the equivalent node force field through the steam pressure field, the equivalent load is applied to the steam pressure field, the precision is high, and the actual value of the steam pressure can be reduced to a great extent; the application process is independent, geometric models do not need to be modified, and the simulation effect is good.
