摘　　要：针对采用一体化设计、整体式车身结构的多轴车辆,建立刚柔耦合虚拟样机模型,对多轴车辆的平顺性进行研究。基于驾驶室连接方式、驾驶室结构形式和驾驶室顶部连通形式3个设计要素,分析整车在不同载重和不同工况下的平顺性。分析表明,带有斜支撑桁架结构的驾驶室能够有效降低车辆行驶时驾驶室的加权加速度均方根值;顶部不连通的结构形式驾驶室舒适性更好;通过优化驾驶室结构形式和顶部连通形式,车辆在空载和满载情况下的平顺性得到了较大的改善,能够更好地满足使用要求。For multi-axle vehicle which use integrated design and integral body structure,rigid-flexible coupling virtual prototype model is established,which analyzes ride comfort of distributed driving multi-axle vehicle.On base of different connective with cab and body and different cab structure,ride comfort of vehicle is given with different load and different run case.Root mean square value of vibration acceleration of the truss structure cab with inclined support is effectively reduced.Comfort of the cab with no-connectivity top structure is better.Through optimize cab's structure form and top link shape,ride comfort of vehicle improves better on case of empty-load and full-load,which can satisfy the demands.
