An exclusive sports car manufacturer required a systems integrator to design and build a carbon composite brake bedding system (Brake Conditioning Rig). This would help with determining the rate of wear on the brake pads as well as the degree of heat generated.
The brake callipers and disc for each wheel are fitted prior to running the test. When the rig is in a safe condition, a predefined brake bedding schedule is run. This consists of numerous iterations of spinning the disks up to a predefined speed, then applying the brake callipers to bring the brake disks to rest. Actuating the brake calliper pistons is achieved with a compressed nitrogen gas system controlled by a current output demand from within the test schedule.
The solution requirements were achieved by using the Siemens S7 1500 PLC, where standard and safe I/O are better integrated. The overall design was simplified and the objectives of the project were achieved as follows:
