A new concept of a tire and suspension evaluation system based on the real-time vehicle dynamics analysis with measured tire force is discussed in this paper. A testing machine was developed by authors following this concept, in which a six degree-of-freedom motion platform was used to realize various contact conditions of the tire. It is well known that the tire characteristics are important factors for the dynamic analysis of an automobile, and the suspension setting has a strong influence to the contact conditions of a tire. Therefore, it is important to evaluate the tire characteristics including the effects of the suspension system. The test results with developed testing machine were compared with the running test results using an actual automobile, and the advantage of the new concept and developed tire-suspension testing machine was discussed.
