- Abstract
Considering that the suspension acts as an important way to transfer the forces and moments acting between the wheel and the frame, the performance of the suspension will directly affect the smoothness of the electric wheeled vehicle. In order to verify the practicability of this mathematical model, the frequency response function from the input of the front wheel road surface roughness displacement input to the seat vibration acceleration is established using the MATLAB software programming language, and the rear wheel road surface roughness displacement input is input into the powertrain pitch angle vibration displacement. Inter-frequency response function and simultaneously, the SIMULINK platform is used to simulate the time-domain response of the basic seat, the center of mass of the vehicle body, the vertical acceleration of the center of mass of the powertrain, and the time domain response of the pitch angle of the vehicle body and the powertrain. Bench test and simulation results show that: the fault suspension under the control of the active fault-tolerant controller lags behind its performance level after some time and can quickly recover to the same performance as the fault-free automotive semi-active suspension level.
