| Abstract: | Resonance is a problem in the rotor-bearing system.In the rotor-bearing system, the bearings are relatively independent and liable to change, and their physical parameters have a great influence on the dynamic properties of the structure.This paper establishes a mathematical model of trequency optimization for the system by means of mathematical planing,and,on the basis of sensibility analysis,proposes a solution for the redesign of dynamic modification in order to avoid resonance.Moreover, a practical example is given to illustrate its applications and effectiveness of the method. |
