TRW Uses New Simulation Method to Simulate Brake Squeal Problems Early in Design Process - Article
Friction-induced brake squeal has been a challenging issue for the automotive industry for decades and has become particularly important as other sources of noise have been reduced or eliminated. Up to now, TRW and other brake producers have relied upon a brake squeal simulation method in which interfaces between brake pads and rotors and other components were manually modeled prior to performing fi nite element analysis (FEA). The weakness of this approach is that it requires assumptions of how the components will contact each other that must be validated by physical testing. This takes considerable time and money and delays the product development process.
