Abstract：[Objective]In order to analyze the influence of different driving arrangements on the dynamic performance of the parallel rotary forging press and improve the comprehensive dynamic performance of the rotary forging press,the driving arrangement of the parallel rotary forging press was selected and analyzed and scaled.[Methods]The parallel mechanism was introduced into the rotary forging press as a motion actuator,and a general model of the rotary forging press was established by using an inclination angle between the static platform and the slideway as a variable parameter to represent the variable driving arrangement.Based on the intensive analysis of the impact of different driving arrangements on the dynamic acceleration performance of the mobile platform,the average acceleration and the dexterity were used as dynamic performance indicators,and a multi-objective optimization method was used to obtain the mechanism size with the optimal comprehensive performance.A Jacobian matrix and acceleration of the general model were derived.Based on the acceleration performance curves,the acceleration results at different inclination angles were compared and analyzed.[Results]The results show that the comprehensive dynamic performance of the rotary forging press optimized by the structural size is the best under the vertical driving arrangement.
