Abstract：The installation of interference ft bolt is important for the interference ft long-life joining of aircraft. To optimize the electromagnetic force installation method of interference ft bolt, a fnite element model was developed to investigate the effects of key parameters on the interference ft bolt installation force in electromagnetic riveting method. The results showed that the charging voltage had a signifcant influence on the peak installation force, however, exhibited little influence on the force pulse width. Both the peak and pulse width of the installation force increased obviously with the increasing of the discharging capacitance at small discharging capacitance, however, the peak installation force was not sensitive to large discharging capacitance. The peak of the installation force decreased linearly with the increasing of the discharging resistance, while the pulse width of the installation force exhibited no relationship with the discharging resistance. Moreover, the peak of the installation force increased obviously with the early increasing thickness of the slave coil, then with the increasing of the thickness, the increasing rate of the peak decreased and fnally reached a constant. To obtain a suitable installation force in service, the large discharging capacitance and low discharging resistance are suggested, and the charging voltage is suggested to control the peak installation force.
