High Fidelity Anti-Lock Brake System Simulation Using Abaqus and Dymola

Accurate simulation of an anti-lock brake system (ABS) requires detailed modeling of separate subsystems in dif-ferent physical domains. Creating refined models of the brake, wheel, and control components with a single analy-sis tool is difficult, if not impossible. The strategy of co-simulation can be adopted to meet this challenge; differ-ent simulation tools can be used simultaneously to create multi-disciplinary and multi-domain coupling. In this Technology Brief, a co-simulation approach using Abaqus and Dymola is used to achieve a realistic system-level simulation of an ABS. The tire, wheel, brake caliper mechanism, and road are simulated with a detailed Abaqus finite element model while the brake system con-trol algorithm and hydraulics and are simulated with Dy-mola.
