Why enroll

Brake noise remains one of the most challenging NVH issues in automotive engineering. This course provides a structured approach to brake noise diagnosis and control, combining traditional design methods with cutting-edge active noise control strategies.

Essential for NVH engineers, brake system designers, and vehicle dynamics specialists, this training will help professionals implement practical solutions for world-class braking performance in modern passenger cars and EVs.

Understand the need of modal decoupling at the design stage for brake-disc-pad- calliper to mitigate the noise in different frequency bands of harshness

Course details

This course delves into the complexities of brake noise, covering its various forms like brake squeal, judder, and rotor-induced vibrations.

Participants will explore Complex Eigen Analysis, Modal Decoupling solutions, and transfer path analysis to diagnose and mitigate unwanted noise. Special focus will be given to designing brake systems for noise elimination, including the role of vacuum pump noise during actuation.

The course will also introduce advanced active control techniques, such as Active Vibration Control and Active Noise Cancellation (ANC), demonstrating their applications in premium vehicles and EVs for superior in-cab quietness.

Frequently asked questions

A: Uniform oxidation mostly biases brake torque and doesn't sustain a squeal feedback loop. Hydrogen embrittlement needs plating processes and manifests as fracture, not noise drift. Chloride underfilm corrosion lifts the pad locally, reduces effective stiffness, and destabilizes the friction-induced mode. Thermal fatigue of the hat excites judder bands and sits well below squeal frequencies.

A: More clamp force raises energy input and can aggravate squeal modes. A floating architecture with compliance absorbs geometric error before it excites the pad-disc system. Disc runout control helps torque variation but doesn't isolate caliper-induced mode coupling. Higher control gain amplifies structural uncertainty and risks instability.

A: Actuators are isolated from the hydraulic force path and can't remove torque. Electrical saturation doesn't stay purely electrical because the control loop disengages. Saturation collapses the control authority, leaving the passive system intact but noisy. Disc thermal runaway is governed by braking energy, not the small actuator forces.

A: MMC doesn't guarantee alignment once assembled with mating parts. MMC allows geometric error to grow as size departs, which can stack unfavorably. Stiffness isn't defined by a GD&T modifier. Dynamic behavior is directly affected by alignment and constraint conditions.
