This three-axis shaker rig does vibration testing for the full brake assembly. The computer is loaded with road and load profiles gathered from field tests, where trucks record the bumps and jolts they get out on the road. Those bumps and jolts are played back by computer-controlled hydraulic actuators. The brake is bolted to an 'axle' to simulate real-world conditions. The computer amps ups the frequency and amplitude of the vibration to accelerate the actual wear on the brake. A day-long trip can be simulated in less than a hour.
