For concept and design of modern suspension systems many different demands have to be considered. Beside package and lightweight construction especially the real scopes of a suspension system, kinematics and compliance, are getting more and more important to fulfill all technical needs coming from the automotive market. In particular the development of suspension systems for Sports Utility Vehicles (SUVs) has to satisfy very high demands and strong characteristics criteria coming from the On-Road and Off-Road driving. As many different load cases have to be taken into account, an analytic approach can only be used for first concept steps to design a SUV-suspension system. After that it is necessary to verify and tune all suspension and bushing characteristics by the use of multibody simulation tools like e. g. ADAMS. Therefore adequate models of all suspension components have to be available [6].

This paper is looking both at testing and simulation of tyres under stationary and dynamic operation conditions. The new dynamic ika tyre test rig will be introduced and its particular advantages in tyre testing are explained. First results are shown and the reproduction of measured tyre properties with an efficient tyre model is demonstrated.

In this paper, a new kinematics and compliance test rig will be presented. Particularly the design and construction of the test bench is explained. Moreover a typical measuring procedure will be presented in which a certain driving situation is going to be simulated at the test bench. It will also be shown how to validate the computer model of a vehicle for the simulation tool ADAMS with the results of the test bench. By simulating a certain driving maneuvers with ADAMS, the influence of the compliance steer on the road performance of a motor vehicle will be shown in conclusion.
