Aiming at the problem of excessive elastic deformation and inertia force in drive mechanism oftraditional die cutting machine,the force condition of the transmission rod in the driving mechanism based on kinematic principles,and a"I"shaped lightweight driving rod based on a fully symmetrical structure was proposed.The minimum elastic deformation and lightweight of the drive rod were taken as the optimization objectives,and the structural parameters of the drive rod were optimized by using the hybrid combination differential evolution(DE)and Jaya algorithm to improve convergence speed and optimize iteration accuracy.The experimental results show that the maximum deformation of the drive rod is reduced from 0.097 mm to 0.010 mm,and the total weight is reduced from 15.867 kg to 13.960 kg under the working condition of die cutting force of 3.43×106 N and rotational speed of 130 r/min.It is suitable for the die cutting equipment with high speed and high die cutting accuracy.
