“…6 b), where the superimposed longitudinal shear force is directed towards the trailing edge. This sinusoidal-shaped force history is found in numerous experimental investigations of the longitudinal forces on complete rolling tyres [7,8,18,19,20] as well as in the investigation of a single tread block in rolling contact performed by Liu et al [21]. These references also present a measured amplitude ratio between longitudinal and normal force components which is in the same order of magnitude as that of the friction coefficients presented in Fig.…”

A novel test rig design is presented which enables detailed studies of the three force components generated in the impact and release phase of rolling contact between a tyre tread block and a substrate. The design of the compact internal drum test rig provides realistic impact and release angles for the tread block-substrate contact and enables force measurements at high rolling speeds with a high signal-to-noise ratio. Measurements of the rolling contact forces are presented for different values of rolling velocity, static pre-load and acceleration. It is demonstrated that this test rig provides results which contribute to the understanding of tyre-road interaction and can be used as input to modelling-based development of both tyres and roads aiming for improved handling, safety, energy efficiency and comfort.

“…An initial achievement involved designing and building a transducer which contains a transversal array of four sensing elements and which is placed in the rolling surface [15]. The transducer was designed for measuring stress distributions on three orthogonal directions in the contact patch of truck tyres under free rolling, traction or braking conditions.…”
