Influence of construction features and the distribution and size of the payload on the coordinates of the center of gravity in passenger cars

Abstract The coordinates of the center of gravity are the main input geometric parameters in the dynamic models used to assess the stability, handling and braking performance of cars. At the same time, it is known that the location of the center of gravity depends on the design features of the car and the distribution and size of the payload. The use of averaged data on the load on the axles leads to significant inaccuracies when using existing dynamic models. This report presents the results of the study on the influence of the design features and the distribution and size of the payload on the location of the center of gravity in passenger cars and estimates the mistake that is allowed when not taking into account the displacement of the center of mass of the car.
