“…In the literature, a number of dynamometers ('dynos') have been presented to study either brake performance or tire-ground interaction . A limited number of dynos have been conceived for studying the ultimate brake force that the brake may provide to the tire and that the tire may apply to the ground [7,9]. Unfortunately, in [7] the tire-road friction coefficient is replaced by magnetic powder clutch.…”

The paper investigates the dynamics of the tire and brake during hard braking or wheel locking, from the view point of a brake manufacturer. A new test rig, named BRAD (BRembo Automotive Dynamometer) is presented which measures the forces acting both at the brake and at the tire-ground interface. Lateral forces are not measured. In the test rig, the ground is represented by a drum. The features of the test rig are presented. The measurement accuracy is declared. The first result is that, near wheel locking, a substantial part of the braking power is generated by the tire and not by the brake. The test rig quantifies such a partitioning of brake power, which is important for current and future electric motorsport activities. Some 30% of the braking power is due to tire during hard braking. The second result is that, due to such important braking power at the tire, the tire is heated up, which increases considerably the maximum friction. This implies that brakes interact with tires near wheel locking. The new test rig enables to study such an interaction.

“…In [10], a brake&wheel test rig is presented, the focus is mainly on tyre characteristic measurement, brake development is not dealt with. In [11] a relatively simple test rig is introduced with flywheel and magnetic powder clutch to simulate friction at the wheel-ground interface. The focus is on ABS performance.…”

“…Research has been done to solve such issues of the roller braking test bench and flat-bed braking test bench for braking performance testing. 26–30 Based on the working principle of the ABS and the rotational inertia of flywheel, Zhou et al 27–29 designed a vehicle ABS test bench, which is composed of motors, magnetic powder clutches, flywheels, vehicle braking system, and corresponding software operation system. By controlling the real-time transmitted torque of the magnetic powder clutches, the ABS system of a full vehicle could be tested on the test bench.…”

Brake-by-wire systems are one of the key components in intelligent/unmanned vehicles that have attracted worldwide attention. Testing and evaluation of brake-by-wire systems are a significant step during the development of the technology of vehicular braking and further the advancement of intelligent/unmanned vehicles. Using the test bench to simulate different road adhesion coefficients (i.e. road surfaces) and to complete the testing and evaluation of the vehicle braking systems is of great significance and importance. A test bench for simulation of vehicular braking of 1/4 vehicle is presented and investigated in this article. It is composed of a motor, two rollers, a 1/4 vehicle suspension system, a magnetic powder clutch, a flywheel, sensors, a signal acquisition and processing system, and a controller. The wheel and vehicle speeds are simulated by the rollers and flywheel speeds, respectively. The translational kinetic energy of 1/4 vehicle is simulated by the rotational kinetic energy of the flywheel. The signal acquisition and processing system is used to acquire and process the experimental signals, such as rotational speeds and torques during tests. The magnetic powder clutch with adjusted applied currents in the test bench is used to real-timely simulate roads with different adhesion coefficients. Based on the working principle of the test bench and the fundamentals of vehicle dynamics, the prototype of the test bench is established and the simulation approach of the translational kinetic energy of 1/4 vehicle is investigated. The mathematical model of the real-time simulation about roads with different adhesion coefficients based on the magnetic powder clutch with real-time controllable transmitted torque is established. With the built 1/4 vehicle braking systems based on the test bench and road, and the corresponding established models, the comparison and analysis of the simulation results of various road surfaces are conducted. Experiments are sequentially implemented to verify the feasibility and effectiveness of the test bench.
