摘要

临界距离理论适用于计算复杂结构的蠕变疲劳寿命，但在工程实践中该方法的计算效率很低。为解决这一问题，使用 Python 语言对Abaqus软件进行二次开发。所开发软件可以使用临界距离法计算结构的蠕变疲劳寿命，并提供多种功能以提高分析效率，包括模型信息提取、材料参数导入和计算结果输出等。通过对某型高压涡轮叶片进行分析计算验证了软件适用性。结果表明该软件可以有效简化临界距离法的步骤，实现对复杂结构蠕变疲劳寿命的高效计算，具有一定工程价值。

Abstract

The critieal distance theory is suitable for caleulating the creep-fatigue life of complex structures

but the calculation efficiency of this method is very low in engineering. To overcome this shortcoming

Python language was used for the secondary development of Abaqus software. The developed software can calculate the creep-fatigue life of the structure by using the critical distance method. To improve analytical efficiency

various functions were developed in the software

including model information extraction

material parameter import and calculation result output

ete. The applicability of the software was verified by analyzing a high-pressure turbine blade. The results show that the software can efficiently calculate the creep-fatigue life of complex structures by simplifying the steps of the critical distance method

and it has certain engineering value.
