摘要
运用多体动力学软件ADAMS/Car模块建立了包括前后悬架系统、轮胎系统、转向系统的整车模型,设计了虚拟仿真试验台用于随机路面的输入测试。运用该试验台对所建立的整车模型进行平顺性仿真,得到相应数据之后,保持路面情况、轮胎激励、车辆载重、悬架阻尼不变,只改变悬架刚度,仿真车辆在不同悬架刚度下的平顺性,得到悬架刚度对平顺性的影响。仿真结果表明,对于特定车辆要选用合适的悬架刚度才能给车辆平顺性提供保障。
By using multi-body dynamics software ADAMS/Car module ,the model of a vehicle system including the front and rear suspension system ,tire system ,steering system was set up ,the virtual simulation test rig for random road input test was designed . Using the test rig ,the ride comfort of the established vehicle model was analyzed ,to get the corresponding simulation data .Keeping the pavement ,tire motivation ,vehicle load ,suspension damping constant ,only changing the suspension stiffness ,the simulation of vehicle ride comfort under different suspension stiffness was carried ,so as to achieve the influence of suspension stiffness on the ve-hicle ride comfort .The conclusion is that we should choose suitable suspension stiffness for a particular vehicle to guarantee the vehi-cle ride comfort .
