摘　　要：对空间太阳阵导线电阻对焊进行可行性分析,通过有限元建模仿真,开展焊接热场-温度场-应力场数值模拟。结果表明,空间太阳阵导线电阻对焊过程包含受弹塑性变形影响形成面接触的预压过程与电热温度场与焊接应力场间接耦合的焊接过程,通过提取焊接温度场分布的数值模拟计算结果可以快速直观的分析焊接温度场分布的合理性、焊接形成过程中焊接参数的变化趋势,为空间太阳阵导线电阻对焊的工程应用提供理论支撑。Feasibility analysis of space solar array wire welding was carried out, and welding thermal field, temperature field and stress field were numerically simulated through finite element modeling and simulation. The results show that the welding process of space solar array wire includes the pre-pressing process of surface contact affected by elastic-plastic deformation and the indirect coupling process of electro thermal temperature field and welding stress field. By extracting the numerical simulation results of welding temperature field distribution, the reasonable distribution of welding temperature field can be quickly and intuitively analyzed. The changing trend of welding parameters during welding process provides theoretical support for the engineering application of space solar array wire welding.
