Dynamic Brake Test Rig

The Dynamic Brake Test Rig is used to measure the system response parameters of an automobile disc brake (natural frequencies, vibration, transverse and whirl rotor motion). The test rig currently available in METL is capable of speeds up to 150 rpm, or about 10 mph equivalent vehicle speed . The test rig’s main components include a 5 HP drive motor, a 33:1 three stage belt system for speed reduction, a flywheel, a complete single-wheel disc brake system from a 1998 Ford Crown Victoria (master cylinder, brake line, anchor bracket, caliper, pads and rotor), a variable speed frequency control drive, and data acquisition system using Labview.
