摘　　要：针对兼顾汽车行驶平顺性和馈能特性的需求,提出了一种新型磁流变互联悬架模型。先构建磁流变减振器力学与馈能的理论模型,并通过Simulink软件搭建磁流变减振器模型和磁流变互联悬架模型,分析影响馈能特性的主要参数;基于整车仿真模型,以30 km/h车速和一段C级路面为激励输入,对磁流变互联悬架与传统液压互联悬架进行对比仿真,分析互联悬架在实际路面激励下馈能特性和汽车行驶平顺性的变化规律。结果表明:磁流变互联悬架的减振效果更好;在满足车辆行驶平顺性需求的前提下,具有有效回收互联悬架振动能量和提高抗俯仰侧倾的能力。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.
