Abstract

In order to compensate for the lack of active control force in the passive suspension of automobiles, a linear motor type active suspension based on the traditional passive suspension structure was designed. Adding linear motors to the passive suspension can increase the damping force of the active suspension and reduce the vibration of the vehicle. Firstly, the structure of the linear motor was designed. Secondly, Ansys/Maxwell magnetic field analysis software and control variable method were used to optimize the structural dimension parameters of each part of the linear motor. The results showed that the fluctuation of electromagnetic thrust of the linear motor was reduced by 83%, while the steady thrust was increased by 10%. Finally, the simulation model of linear motor active suspension is built in Matlab/Simulink, and fuzzy PID is used to control the linear motor active suspension system. The analysis is carried out in time domain and frequency domain respectively. The results show that: Compared with the passive suspension, the body acceleration, suspension dynamic deflection and tire dynamic load of the linear motor active suspension are effectively inhibited, and the power spectral density of the body acceleration is also greatly reduced, which effectively improves the ride comfort and handling stability of the vehicle.
