Proposed Project:
Measurement Trailer for the Analysis of Tire-Friction Behavior

Faculty Mentor:   Prof. Dr. rer. nat. Hermann Winner
Graduate Student Mentor:Dipl.-Ing. Marcus Reul
Research Location:Technische Universität Darmstadt

Vehicle dynamics in longitudinal, lateral und vertical direction is highly influenced by the tire properties. For the understanding of tire behavior and for further improvements, the physical effects of the tire behavior have to be investigated. The knowledge of these properties is necessary for simulating vehicle dynamics and the interpretation of vehicle dynamic measurements. For the research of tire-friction behavior under real driving conditions, a measurement trailer was developed at the Chair of Automotive Engineering (FZD) at the Technische Universität Darmstadt. With this trailer, the friction behavior between different tires and road surfaces can be examined in driving tests under variable conditions of longitudinal slip, sliding speed, slip angle, camber, and wheel load. Compared to other methods, the construction of the applied braking torque allows braking the wheel in a range above the friction maximum without locking the wheel. Thus, this feature allows the measurement of the complete μ-slip characteristics. Tasks available include design and calibration or experimental work with the trailer on a test track.
