Abstract：In order to improve engineering vehicle road comfort and road-friendliness, co-simulation model with ADAMS/Simulink/AMESim and multi-objective optimization function were established based on 7-DOF whole vehicle interconnected hydro-pneumatic suspension model with considering of the nonlinear characteristic of all components and four-wheel road signal correlation. Co-simulation optimization was achieved by genetic algorithm. The results show that total weighted RMS acceleration of vehicle body decrease by 42.5% and road-friendliness factor decrease by 4.5% compared with the former in the case of speed 60km/h. Road comfort has been greatly improved and road-friendly factor has been slightly improved. Vehicle ride comfort and road-friendliness can be both improved by multiple software co-simulation based on genetic algorithm. The work presented in this paper can be used for the simulation research of multi-axis chassis performance improving in the future.
