Testing and simulating tires on a wet surface: a novel approach
Virtual engineering is vital in automotive development and now requires a wider range of simulations, including non-dry surfaces. Thus, Siemens DISW, together with GCAPS and GM, is developing a novel physics-based wet tire model. Here, wet measurements executed with GCAPS’s wet test rig, with tires supplied by GM, are discussed, and physical trends identified. The wet tire model – an extension of MF-Tyre/MF-Swift – is then shown to replicate measurements, offering a new domain for simulations.
