Abstract

Passive suspension hydraulic shock absorber of a certain minicar is being improved design. Step motor added to adjust settable orifice in valve core bar of shock absorber. For validate feasibility of improved control, simulation model and bench test are being carried out. An efficient modeling method based on software AMESim and MATLAB/Simulink is bring forward aim at relieve complexity of traditional modeling method on vehicle Semi-Active Suspension (SAS). AMESim has abundant sub-library models, and MATLAB has powerful numerical calculation function. Combine AMESim model and MATLAB/Simulink controller model by S-function and to co-simulate. Results of co-simulation and experiment show the modeling method is simple and feasible. And it provides an effective modeling method for vehicle chassis system dynamics.
