Brakes and Detents

Rotational and translational friction and detents that limit, slow, or stop motion

Blocks in the Brakes and Detents library represent elements and frictional forces that limit, slow, and stop motion. Simscape™ Driveline™ brake blocks also have thermal variants that allow you to determine how heat generation affects the efficiency and temperature of driveline components. To determine if your system produces forces and torques that overcome the holding forces produced by brakes and detents, connect these blocks together just as you would assemble a physical driveline system.

Featured Examples

Fixed Caliper Disk Brake

Model, parameterize, and test a caliper disk brake. The example uses numerical data extracted from the tandem primary cylinder datasheet to identify an optimal design for the caliper disk brake. The example shows how to generate a compliance curve for the caliper disk brake.
