Within the AXIOM program, dedicated tests were performed to evaluate the friction behaviour between plastic wheels and different contact surfaces.
The mechanical system required the rotation of an assembly to occur through friction-driven contact between the wheels and the supporting surface. For this reason, it was necessary to experimentally determine the friction coefficient in order to correctly predict the torque transmission and ensure reliable system operation.
A dedicated test setup was developed to measure the friction interaction between plastic wheels and multiple surface materials under controlled conditions.
The resulting experimental data allowed the identification of representative friction coefficient values, supporting the validation of the mechanical design and reducing uncertainties in the performance of the friction-driven rotation system.
