摘　　要：电磁铆接是一种电磁力驱动加载的铆接技术,其铆接驱动力是影响铆钉成形质量的关键因素。为了掌握电磁铆接驱动力的变化规律,运用数学建模方法,简化电磁铆接驱动力求解过程,建立感应式与自激励式电磁铆接驱动力数值计算模型,并通过试验验证了模型建立的可靠性。同时利用MATLAB App Designer对电磁铆接驱动力计算进行了可视化系统的设计,实现了对电磁铆接驱动力的简便计算。基于该系统,以自激励式电磁铆接为例,分析了电参数对铆接驱动力的影响规律。研究结果表明,放电电压和电容的增加以及回路电阻和回路电感的减少,有利于提高自激励式铆接驱动力的峰值和变化速率。Electromagnetic riveting is a riveting technology that is driven by electromagnetic force,and driving force is the most critical factor affecting the forming quality of rivets.In order to master the influence law of driving force in electromagnetic riveting,the mathematical modeling method is used to simplify the solution process of driving force in electromagnetic riveting process,and the numerical calculation model of driving force in inductive and self-excited electromagnetic riveting is established.And the reliability of the numerical calculation model was verified by the experiment.At the same time,the MATLAB App Designer is used to design the visualization system for the calculation of the driving force of electromagnetic riveting,and the simple and convenient calculation of the driving force of electromagnetic riveting is realized.Based on this system,the influence law of the electrical parameters of the self-excited electromagnetic riveting is analyzed.The results show that the increase of discharge voltage and capacitance,and the decrease of loop resistance and loop inductance are beneficial to improve the peak value and change rate of the electromagnetic driving force of electromagnetic riveting.
