As a result of the 1st International Colloquium on Tire Models for Vehicle Dynamics Analysis in 1991, the international TYDEX Workshop working group was established. This workshop concentrated on the standardization of the exchange of tire measurement data and the interface between tire and vehicle models in order to improve the communications between vehicle manufacturers, suppliers, and research organizations. The development and knowledge of tire behavior is of great importance to both the tire and vehicle industries and will be intensified. Therefore the TYDEX Workshop received great interest from all parties to come to some kind of standardization. In the two expert groups, one of which focused on Tire Measurements — Tire Modeling and the other on Tire Modeling — Vehicle Modeling, the TYDEX-Format and the standard tire interface have been developed, which will be explained in this paper. Furthermore, a short overview of the European TIME project aiming at a standard tire testing procedure will be given, which is reliable and consistent with realistic driving conditions. Standard testing procedures are some of the important consequences of the TYDEX Workshop.

Manager Development, MSC Software Benelux B.V.Because accurate modeling of the tire-road interaction forces forms the basis for virtual prototyping analysis in the field of vehicle dynamics, tire modeling has always been a key item of the Automatic Dynamic Analysis of Mechanical Systems (ADAMS) product line. This paper briefly explains the current ADAMS offering in tire modeling and the approach taken for the TMPT benchmark program. When the TMPT benchmark program is considered as a test case for vehicle dynamics tire models, ADAMS has proved to have adequate functionality in the tire/road interface and to provide the user with a wide range of tire models to pass this test successfully.
