In this paper, the main purpose is the calculation of mass transfer due to road roughness in different maneuvers including of the vehicle accelerating and braking. To achieve this goal, the damping model of a full car for 10 degrees of freedom, based on the vibrations in MATLAB software was Simulated. Vertical displacement of the wheels on uneven roads based on ISO classification at a constant speed of 70 km per hour and the general direction of the vehicle was 1,000 meters. The following, using inverse dynamics analysis in MATLAB Simulink, the forces acting on each wheel of the vehicle during various maneuvers was obtained. Finally, using of force histories resulting in the wheels of to cross the road roughness, as well as accelerating and braking, rate of mass transfer from back to front in the braking maneuver and rate of mass transfer from the front to the rear of the vehicle in the accelerating maneuvers was obtained.
