- Abstract:
- In order to demonstrate the superiority of the active suspension in improving the ride comfort of the vehicle, on the basis of establishing the 1/4 active suspension model of the vehicle and the stochastic road excitation model, the linear optimal control is used as the control strategy of the active suspension, and the design The linear optimal controller is used to establish the active suspension simulation model in the frequency domain and time domain by using MATLAB, and the active suspension is simulated in the frequency domain and time domain respectively on the random road excitation and compared with the passive suspension. The results show that : The active suspension can effectively reduce the body acceleration, tire dynamic load and suspension deflection, thereby significantly improving the ride comfort and handling stability of the car. The model establishment, optimal design and simulation analysis of this design are the further development of the active suspension. It provides a useful reference for research and practical application.
