【Abstract】 For the purpose of taking into account the ride comfort and energy regenerative characteristics of vehicle,a new type of magnetorheological interconnected suspension model was proposed.First,the theoretical models of the magnetorheological absorber mechanics and energy regeneration were constructed.Then,the magnetorheological absorber model and magnetorheological interconnected suspension model were constructed through the Simulink software to investigate the main parameters that affect the energy regenerative characteristics.Based on the vehicle simulation model,with vehicle speed of 30 km/h and one segment of Cgrade road as input,a contrast simulation was conducted on the magnetorheological interconnected suspension and the traditional hydraulic interconnected suspension to investigate the characteristics of energy regeneration and the car ride comfort under the excitation of the actual road.The results show that the vehicle with the magnetorheological interconnected suspension has a remarkable vibration damping effect against the traditional suspensions.Moreover,the magnetorheological interconnected suspension can effectively regenerate the vibration energy of the interconnected suspension and improve the ability of anti-pitch and roll while meeting the ride comfort requirements of vehicle.更多还原
