摘要

对CAE软件进行后处理二次开发是评估铁道车辆焊接构架疲劳强度的一种高效方法。文章以ABAQUS为平台，采用Python语言和ABAQUS/GUI工具包开发构架疲劳强度评估程序，对结果文件中的数据进行快速提取与处理，建立母材与焊缝局部坐标系，基于DVS 1612标准获得评估点在局部坐标系下的综合材料利用度并写入结果文件，实现构架疲劳强度快速分析与可视化。该方法为评估构架疲劳强度提供一种高效、可行的方法，也为ABAQUS后处理二次开发在其他领域的应用提供指导和参考。

Abstract

Conducting secondary development on CAE software for post-processing stands as an efficacious approach to evaluate fatigue strength in welded frames of railway vehicles. This paper presents a fatigue strength evaluation program for welded frames

employing ABAQUS as the platform and utilizing Python language along with the ABAQUS/GUI toolkit. This program is devised to rapidly extract data from result files

process them

establish local coordinate systems of base metal and welds

and generate comprehensive material utilizations at evaluation points in the local coordinate systems based on the DVS 1612 standard

and write them into result files

enabling rapid analysis and visualization of fatigue strength in welded frames. The proposed approach offers an efficient and feasible way for evaluating fatigue strength in welded frames. This study provides valuable insights for extending the applications of ABAQUS secondary development for post-processing in other domains.
