Motion Test Lab Brake Tester

Brake Tester With Computer

The purpose of the system is to measure the braking force available from the DUT (brake caliper assembly) as the servo drive rotates the shaft/rotor disk when it is actuated.

The Motion Test Lab brake test system mechanical structure is built around a vertical servo driven shaft assembly coupled through a torque transducer to the rotor of the brake device under test: an electrically actuated disk brake assembly.

The rotor and caliper assemblies are coupled to the top of the shaft system which protrudes through the floor of a thermal chamber. The caliper assembly is mounted to a fixture plate on the floor of the chamber to simulate actual “on-vehicle” operating conditions.

The LabView software in the test system is set-up as a recipe-based application so that the customer can run different shaft speed/chamber temperature cycles during disk brake performance validation runs across several model lines. DUT performance data is collected and stored locally, then transferred to a corporate SQL database.
