Abstract

The invention provides a sealing strip creating method and device. The method comprises the steps that at least one path of a to-be-created sealing strip in a CAE model is acquired; for each path, llnodes on the path and associated components on the path are obtained; the attribute information of a to-be-created sealing strip on the path is obtained. The method is advantaged in that according tothe attribute information, all nodes on the path and associated components on the path, each unit and a local coordinate system on at least one node of the path are created, and each unit and the local coordinate system are stored into a corresponding collector, and thereby automatic creation of the sealing strip is realized, manual creation of the sealing strip is avoided, and reliability of thesealing strip is improved; creation efficiency is improved, and credibility and comparability of finite element analysis results are ensured.

Description

technical field [0001] The invention relates to the technical field of computer aided engineering, in particular to a method and device for creating a sealing strip. Background technique [0002] At present, the automobile sealing strip is one of the important parts of the automobile. It is used to fill the gap between the various components of the automobile, and has the functions of shock absorption, waterproof, dustproof, sound insulation, and decoration. When using finite element software to perform finite element analysis on auto parts, it is often necessary to consider the influence of sealing strips on the stress transfer between parts, as well as the isolation effect on vibration and noise. [0003] At present, most of the industry adopts the method of manually creating elastic elements and mass elements step by step to simulate the stiffness and quality of the sealing strip. The work efficiency is low, and different operators have different processing results, which...
