Numerical Simulation and Parameter Analysis of Electromagnetic Riveting Process for Ti-6Al-4V Titanium Rivet

Electromagnetic riveting process (EMR) is a high-speed impact connection technology with the advantages of fast loading speed, large force and stable rivet deformation. In this work, axisymmetric sequential loose electromagnetic-structural coupling simulation models were conducted to perform electromagnetic Ti-6Al-4V titanium rivet, parameter analysis setup was performed based on coupled results. addition, single-objective optimization problem punch displacement using Hooke–Jeeves algorithm. Based adaptive remeshing adopted in air meshes, deformation calculated structural field well transferred model. Thus, results presented higher accuracy speed than numerical The maximum relative difference (EMF) driver plate radial shaft 34.86% 13.43%, respectively. showed that outer diameter height had significant first-order effect response displacement, while platform height, transition zone angle, width amplifier strong interaction effect. Using obtained optimal parameters, effectively improved from 6.13 8.12 m/s 32.46% increase. Furthermore, increasing 3.38 3.81 mm would lead an 80.55% increase shaft. This indicated efficiently by
