Hardware and Virtual Test-rigs for Automotive Steel Wheels Design 2020-01-1231
The aim of this paper is to study in deep the peculiar test-rigs and experimental procedures adopted to the fulfilment of the principal requirements of automotive steel wheels, in particular regarding fatigue damaging. In the discussion, the standard requirements, the OEM specifications and the dimensional and geometric tolerances are approached. As result of an increasingly necessity to improve the performance of the components, innovative virtual test benches are presented. Differently from their traditional precursors, virtual test-rigs gives an extended view of the physical behaviour of the component as the possibility to monitor stress-strain distribution. In the first section, the state of the art and the specifications are listed. Secondly, the adopted hardware test-rigs as the experimental tests are described in detail. In the third one, the new generation of virtual test-rigs are discussed. Finally, an experimental to numerical results comparison is performed focusing on the obtainable details.
