The principal mechanics of a car brake system has not changed since more than 100 years, but brake noise vibration issues still remain challenging not only for the car manufactures and their suppliers, but also for the basic researchers at universities. In order to predict noise and vibration behavior of the brake system and furthermore design and evaluate countermeasures, simulation tools have been extensively applied. Despite its well-known disadvantages, the so called ‘Complex Eigenvalue Analysis’ (CEA) is the preferred tool for industry applications, because its fast calculation time and it’s easy to apply.
