In order to shorten the time, the flow drill screwdriving connection of aluminum alloy materials E170 and SF36 was studied.The experiments was designed by using the response surface method (RSM). The regression equation between three process parameters of tightening torque, deceleration threshold and tightening speed and step time of final tightening was established.The impact between the three parameters and the step time was analyzed through quadratic response surface.By setting the minimum step time of final tightening as the optimization goal, the optional parameters were obtained.Comparative experiments indicate that after using the optimized parameters,the joint connection quality is basically not affected, but the tightening time is only 46.6% of the original time, and the optimized parameters are effective.
