A methodology to simulate the performance of automotive brake systems
Författare
Summary, in English
Different simulation approaches can be employed depending on the specific aspects being evaluated. A macro-scale approach utilizing finite element analysis (FEA) can be applied to assess the global coefficient of friction (COF) of a disc brake system. The global COF can also be estimated by utilizing 3D friction pvT-maps, which are derived from analysing and filtering experimental data obtained from tests conducted on a reduced-scale dynamometer bench. Conversely, a meso-scale approach using cellular automaton (CA) simulation can be employed to analyse local contact behaviour on the disc and pad surfaces and to examine the influence of single ingredients of a friction material compound. This method is capable of investigating plateau dynamics and its impact on brake system performance.
