Investigation on Semi-active Controlled Vehicle Suspension Based on Adams-Matlab Co-simulation

A 1/4 vehicle suspension model with stochastic road excitation was built by ADAMS. A semi-active vehicle control strategy on revised Bingham model was designed by MATLAB. Then effects of passive control, semi-active on-off control and semi-active control on revised Bingham model were investigated based on ADAMS-MATLAB co-simulation. It is found that compared to passive suspension, the proposed semi-active control on revised Bingham model can reduce the vehicle suspension system’s body acceleration, suspension deformation, wheel force, and wheel by 27%,17.6%,9.7%,18.6%, but the semi-active on-off control can only reduce these parameters by 19.6%,9.2%,7.4%,9.3%. This shows that the proposed semi-active control on revised Bingham model is much better than the other two control strategies.
