A Novel Semi-empirical Dynamic Brake Model for Automotive Applications
Artikel i vetenskaplig tidskrift, 2020

In this work, the authors propose a semi-empirical dynamic brake model with the intent of improving the simulation fidelity of Model-, Software-, and Hardware-in-the-Loop environment in vehicle dynamics studies. This model has been parametrized and validated for three passenger cars’ brake systems composed of ECE linings and cast iron discs. The proposed model outperforms the State-of-the-Art by accounting for changes in the interfacial properties and thermal state at the brake pad-disc contact. This work is the result of a joint collaboration between Technische Universität Ilmenau (Ilmenau, Germany) and Volvo Cars (Gothenburg, Sweden). The results show that the braking time, disc temperature and local contact pressure play a fundamental role on the contact area dynamics and, hence, on the friction coefficient.
