摘 要：Based on the principle of speed superposition,the oscillation system for continuous casting mold synchronously driven by double servomotors can adjust all parameters online with high reliability and high bearing *** elastodynamic model of the oscillation system was presented to analyze the oscillation characteristics affected by multiple ***,the working principle of the system was illustrated,with the kinematic model of the system *** the elastic deformation of mechanical components,the lumped parameter method was used to establish the equivalent component and elastodynamic model of the oscillation *** on Runge–Kutta method,the oscillation response of the system was *** validity of the elastodynamic model was validated by comparing the simulated solution and experimental data,and the oscillation characteristics of the system were analyzed emphatically with model *** results showed that the first three harmonic frequencies of the eccentric shafts are the main cause of harmonic resonance,which has a strong relationship with the system *** increase in the fluctuation coefficients and the decrease in the phase difference enhanced the elastic oscillation of the *** elastic error tends to show linear growth with the increase in the friction force of the slab.
