Scaled Test Stand Simulation for Studying the Behavior of Anti-lock Brake Systems on Bumpy Roads

The paper presents a design concept for a scaled-down test stand that allows studying of various possible anti-lock brake system algorithms, by considering a quarter car model traveling over an uneven road surface (a bumpy road, or a road with continuous variable friction coefficient), represented by a rolling inertial tambour track, in contact with an articulated braking wheel. The concept is transposed in a CAD model simulation where motion analysis can be conducted. Also a software application is designed for generating a road surface profile (for the CAD model) and verifying it against the real motion of a smart servo motor. The combined simulation results prove the viability of the concept and encourage the authors to further develop this scaled test stand.
