相比普通导线扩径导线更加经济、环保，采用有限元方法对扩径导线进行应力分析能够为其应用提供技术支持。针对扩径导线有限元建模问题，以JLXK/G1A-530(630)/453号扩径导线为例，研究扩径导线空间结构，确定股线的接触位置，并进行了参数化的有限元建模。结果表明：提出的有限元建模方法通过接触位置确定，可减小接触的面积，从而可减少接触非线性计算的时间；采用参数化建模可研究不同结构参数的扩径导线，减少建模工作量。

Compared with ordinary conductor, the expanded conductor is more economic and environmentally friendly. The finite element method can provide technical support for the stress analysis of the expanded conductor. To solve the problem of the finite element modelling of the expanded conductor, this essay took JLXK/G1A-530 (630) 45 3 expanded conductor as an example, and confirmed the contact position between strands based on the study of the space structure of the expanded conductor. Then parameteric finite element modelling was carried out. The result shows that the time spent on contact nonlinear calculation can be reduced with the confirmation of the contact position between strands, which can reduce the area of contact. Accordingly, the parametric modeling can help to study expanded conductor with different structural parameters and reduce the workload of modelling.
