摘要:
为了研究重型卡车动态参数对驾驶员舒适性的影响,以路面随机不平度为激扰,以驾驶室座椅垂向、驾驶室的俯仰角和侧倾角的加权加速度均方根值为目标函数,建立了13自由度的三维动力学模型.采用Matlab/Simulink软件对整车模型进行仿真计算,分析了不同系统参数,如悬架、轮胎、驾驶室悬架和驾驶员座椅悬架的参数对驾驶员座椅垂向振动、驾驶室前后和左右晃动的影响.研究结果表明:悬架系统中刚度和阻尼参数的最佳匹配对车辆平顺性的影响非常明显;随着悬架系统和轮胎刚度的增加,车辆平顺性从优向劣转变,而随着悬架系统阻尼的增加,车辆平顺性呈现从劣转优现象.该研究为重型卡车悬架系统设计提供相应的理论依据.
Abstract:
In order to study the influence of heavy vehicle dynamic parameters on ride comfort with random road excitation, a 3D dynamic model with 13-DOF(degree of freedom)is established for simulation, and the weighted r.m.s acceleration responses of the vertical drivers seat, pitch and roll angle of the cab are chosen as objective functions which uses Matlab/Simulink software to simulate and calculate the objective functions. The influence of the different vehicle dynamics system parameters on the vertical vibration of drivers seat, pitch and roll of the cab which include the stiffness and damping of vehicle suspension, tires, cab suspension and the drivers seat suspension are analyzed in this paper. The results show that the influence of the stiffness and damping parameters in the suspension systems on the vehicle ride comfort is very obvious. The vehicle ride comfort is going to be worse with the increase of the stiffness of the suspension systems and tires. And the vehicle ride comfort is improved with the increase of the damping of the suspension systems. This study can provide a theoretical basis for the suspension system design of heavy trucks.
