Tyre Test Rig
Table of contents
Functional description
The tire test stand, designed as an external drum type, offers testing possibilities for motorcycle tires, car tires and light truck tires. The two main assemblies of the external drum tire test stand are the steel drum with the drive unit and the test stand structure with the force and torque transducers of the measuring hub and the actuators. The tire is pressed onto the drum with an adjustable normal force (wheel load) by means of a centrally arranged hydraulic lifting rotary unit. The test stand allows the variation of various parameters such as speed, wheel load, slip angle, camber, direction of rotation and inflation pressure. The very rigid test rig design with natural frequencies above the primary tire vibration frequencies allows a highly accurate and reproducible identification of tire vibration modes.
Main areas of investigation
Tire vibration behavior and fatigue
- Cleat crossing at different speeds
- Quasi-static and dynamic tire deformation
- Suitability for indirect tire pressure control
- Tests for high-load and high-speed strength
- Application tests
- Homologation tests
- Uniformity tests
Lateral force behavior
- Quasi-static and dynamic lateral force characteristics
- Temperature dependence of tire characteristics
- Comparative measurements of rolling resistance
- Investigations according to the TIME procedure
- Rut sensitivity, parking
Measured variables
- Forces and torques on the wheel in x, y, z direction (6-component measuring hub)
- Wheel position, speed
- tire deflection
- Tire tread temperature
- Inflation pressure (direct: sensor in the tire)
Miscellaneous
- Different drum surfaces possible: Steel, Korund, bolt on segments with different road surfaces
- Dynamic inflation pressure control (0..6 bar)
