Dynamic Characteristics of Magnetic Levitation Rotor System of Vehicles
In response to the dynamic coupling problem of the magnetic levitation rotor system of vehi-cles,the Euler angular coordinate transformation method was used.Based on a seven-degree-of-free-dom vehicle dynamics model and a five-degree-of-freedom rotor dynamics model,a dynamic coupling model of the magnetic levitation rotor system of vehicles was established.The effectiveness of the model was verified,and the dynamic characteristics of the system under different road excitation and magnetic levitation bearing control parameters were studied.The experimental results show that there is a dynam-ic coupling effect in the magnetic levitation rotor system of vehicles,and the vertical excitation frequen-cy and rotor rotation frequency of the vehicle appear in the dynamic response.The amplitude of the ve-hicle system and the magnetic levitation rotor system increases with the increase in road excitation am-plitude and decreases with the increase in road excitation frequency.Increasing the proportional and differential coefficients within a certain range will reduce the amplitude of the system.
