The parameters of the dynamic vibration absorber used to suppress the excessive vibration of the rotor system were designed to optimize the vibration suppression. The dynamic equation of the dynamic vibration absorber-rotor coupling system was established by using the finite element method

and the response expression of the half-numerical half-resolution of the coupled system was obtained. The design optimization strategy was used to find the best design variable of the dynamic vibration absorber by combining the coordinate solution of the response solution and the bounded boundary. The sensitivity of the dynamic vibration absorber to the optimal deviation of different parameters was analyzed by comparing with the existing optimal design method of dynamic vibration absorber. The results show that the optimized the dynamic vibration absorber can reduce the amplitude of first order resonance by 45.4%

which shows the effectiveness of the method; this method is 11.2% and 9% higher than that of two effective conventional optimization methods

which can optimize the optimization effect of the dynamic vibration absorber; compared with the damped optimal deviation

the vibration suppression performance of the dynamic optimized vibration absorber has a higher sensitivity the optimal deviation of stiffness.
