摘　　要：在飞机蒙皮锤铆中,铆钉的变形需要几十次冲击才能实现,锤铆活塞初速度载荷加载循环问题为分析过程带来了困难。提出利用ABAQUS中Python极强的扩展性,通过二次开发得到连续锤铆过程自动分析的软件方法。通过对初速度、分析时间、冲击次数等输入参数的调整,自动完成锤铆仿真分析,使铆钉达到变形要求。与手动单次迭代方法比较,所提出的软件方法及相应仿真程序在保证镦头成型要求情况下极大地提高了锤铆仿真分析的效率,为后续研究工艺参数优化与铆接质量评价等问题带来指导与便利。与锤铆工艺试验的对比分析,验证了仿真结果的正确性。In the aircraft skin hanuner riveting, the deformation of the rivet needs several tens of impacts to realize, and the problem of the initial speed loading cycle of the hammer rivet piston brings difficulties to the analysis process. This paper proposes a software method of automatic analysis of continuous hammer and rivet process by secondary development using the extremely extensibility of Python in ABAQUS. Through the adjustment of input parameters such as initial speed, analysis time and impact times, the hammer and rivet simulation analysis is completed automatically to make the rivet meet the deformation requirements. Compared with the manual single iteration method, the proposed software method and the corresponding simulation program greatly improve the efficiency of hammer riveting simulation analysis under the condition of guaranteeing the heading forming, and bring about the further research on the process parameters optimization and riveting quality evaluation guidance and convenience. Compared with the hammer riveting technology test, the simulation results verify the correctness.
