为研究大型载重货车对路面的动作用力,建立了五自由度三轴货车动力学模型,以路面随机不平度为激扰,研究车辆动载荷和动载系数随路面等级、车速、载重量、悬架参数的变化规律.结果表明:路面等级下降、提高车速都会使三轴货车各轮动载荷和动载系数增大;减小平衡悬架阻尼和增大平衡悬架刚度,则对三轴货车的中间轮和后轮的动载荷影响比较大;提高载重量,车辆各轮对路面的总作用力增大.

The 3一axle vehicle model was established for the study of vehicle dynamic load that the trucks acton the road．Based 0n the road roughness，the change law of vehicle dynamic load and dynamic load coeffi—cient，which are effected by road level、vehicle velocity、weight and suspension parameters，were studied．Itwas found that when the road level is degraded or the vehicle speed is higher，the dynamic load and the dy—namic load coefficient of each wheel are to increase．The reduction of the balanced suspension damping or theincrease of the balanced suspension stiffness would cause the dynamic load of the middle and the rear wheels toincrease．When the weight is added，the total 10ad acting on the road is raised．
