“…A car is a complex system, which is subjected to influence of varied dynamic forces and environmental conditions with a wide frequency range [17]. The literature distinguishes two main types of loads acting on a vehicle: static and dynamic [18][19]. In the first case, they are related to loading of the car body with a torsional moment, resulting from application of forces from the suspension system, from the surface and the bending moment, resulting from the weight of the vehicles, driver, passengers and transported load.…”

“…In the first case, they are related to loading of the car body with a torsional moment, resulting from application of forces from the suspension system, from the surface and the bending moment, resulting from the weight of the vehicles, driver, passengers and transported load. In the latter case, however, they are result of conditions related to the speed and acceleration of the car, as well as the conditions acting on a vehicle when taking a turn, driving on bumps, braking and accelerating [18][19][20].…”

This paper discusses impact of changes in the load size and distribution in passenger cars on geometry of the suspension and steering systems. It was found to have a major impact on the road safety. The research was carried out with the four most popular suspension system designs used in modern passenger cars, i.e. multi-link suspension on both front and rear axles, only on the front axle, only on the rear axle and a simple suspension design for both front and rear axles. Eight load variants were used for the tests. Changes in the following wheel geometry parameters were identified: toe-in and camber angles of all the wheels and castors for the front wheels. The numerical relationships were determined between the load distribution and sizes and changes in suspension and steering systems in passenger cars. It was found that cars with multi-link suspension in both front and rear axles adapt best to changes in weight and load distribution.

“…These are usually general remarks, stating that the manner of a car use affects the car body condition [14]. Nevertheless, the authors of [9] have analysed the effect of the passenger car mileage on changes in the floor panel geometry. According to their findings, the maximum permissible changes of the body geometry (3 mm) at some base points occur after 150,000 km [9]…”
