- Abstract:
-
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.
