Firstly,The dynamics model of an SUV was established by using multi-body dynamics simulation software ADAMS/View.Secondly,the vehicle ride comfort experiment was carried out,the longitudinal,lateral and vertical vibration acceleration signals of the vehicle body were acquired by the data acquisition device when the vehicle passed the rough concrete pavement and the speed bump,respectively,and the accuracy of the model is verified by the acceleration vibration response of the vehicle.Final-ly.Based on ADAMS and isight co-simulation technology,multi-island genetic algorithm was used to optimize the stiffness and damping of the front and rear suspensions in order to improve ride comfort and stability.The suspension parameters obtained after optimization can not only improve the ride comfort,but also improve the driving stability of the vehicle,and the contradiction be-tween ride comfort and stability is well solved in the process of vehicle driving.
