摘要

The operational stability plays a predominant role in the design of all components of a vehicle. Forces and torques introduced into the components as a result of external excitations have a significant effect on the service life of these components. We know from the classical calculation of the service life that the frequency of the load alternations and the amplitude are the main factors affecting material fatigue. This is important as the consistent application of lightweight construction means that all components are not designed for permanent strength but are dimensioned for a certain defined service life. On the other hand, this means that the component can only endure a finite number of load alternations. A significant proportion of the excitations affecting a vehicle come from the unevenness of the road. These excitations are passed on to the wheels via the tires and then to the chassis and finally to the car body - and to the occupants too of course. This is why it is so important to know the tire properties influencing this transfer mechanism. When designing the parts of the chassis and the body, it is important to assume "reasonable" and "realistic" overall load configurations in order to avoid over dimensioning the components. This would make them extremely heavy and in turn affect their operational stability.
