摘　　要：建立了基于Sim Mechnics的悬架模型,该模型能更真实的反映悬架特性,并且根据实际工程应用场合的不同,此模型还能方便的进行扩展或缩减,无需复杂的数学推导。应用此模型对汽车悬架在多种工况下进行了仿真,结果表明车身的俯仰或侧倾运动对汽车行驶加速度敏感,且加速度绝对值越大,车身俯仰或侧倾运动越剧烈;在转弯工况下对汽车转向角敏感。基于Sim Mechnics悬架模型的建立和仿真分析,为全车悬架的主动控制研究提供了更贴近工程实际的被控对象模型。The suspension model based on SimMechnics is built,which can be more actual to reflect suspension property.According to actual project application occasion,this model can be conveniently developed or reduced without complex mathematics derivation.Simulation applied this model in various operating mode,and the result showed that the roll or the pitch of auto body was sensitive for the vehicle travel acceleration,the acceleration absolute value bigger,and the roll or the pitch of auto body more violent.The suspension model based on SimMechnics was built and simulated,which offered the controlled object model keeping close to the reality of project for the whole vehicle suspension active control.
