Abstract

The invention discloses a perfusion core material parametric modeling analysis method based on an APDL language, and relates to the field. Comprising the following steps: step 1, constructing a geometric model of a basic surface of a minimum unit of a perfusion core material based on an APDL language, respectively determining material attributes of a core material model and a resin model, and defining unit types of the core material model and the resin model; 2, generating a finite element model of the minimum unit of the perfusion core material based on an APDL language; 3, based on an APDL language, multiple times of mirroring and copying are carried out to generate a complete perfusion core material finite element model; 4, defining a finite element model analysis type based on an APDL language, applying a load to the perfusion core material, and solving; and 5, finally, performing post-processing observation based on an APDL language, analyzing a calculation result, and outputting deformation, stress and displacement conditions of the perfusion core material. The method has the beneficial effects that parametric modeling of the perfusion core material is realized by using an APDL language, the efficiency is effectively improved, and errors are reduced.

Description

technical field [0001] The invention mainly relates to the technical field of chemical equipment, in particular to a parametric modeling and analysis method of perfusion core material based on APDL language. Background technique [0002] The disadvantages of the traditional composite material molding process in terms of technology and environmental protection have gradually become prominent with the increase in production capacity demand and the improvement of environmental standards, which largely hinders the promotion and application of composite materials. The vacuum infusion molding process came into being and has been widely used for its advantages of good performance, high efficiency and low cost. The process is mainly divided into two types: high permeability medium type and groove type. Compared with the high-permeability medium-type vacuum infusion process, the groove-type vacuum injection molding process does not require high-permeability medium and peeling materi...
