Brake vibrations are a typical example of NVH (noise, vibrations harshness) problems in automotive industry. Costs of development processes of automotive brakes are nowadays dominated by optimization with respect to the NVH behavior. The aim of this project is to optimize brakes with respect of being calm and smooth, i.e. the opposite of being noisy, showing vibrations and harshness by using deliberately introduced damping. The project intends to model the influence of different damping ressources in brakes especially focusing on shims.Such devices are used especially in automotive disk brakes for the suppression of squeal. But so far, the state of the art of understanding of the working principle as well as the modeling is very weak. The project aims to experimentally investigate and to model the behavior of shims. These models are introduced into large FE codes of complete brakes and the stability behavior of the entire system is investigated.

制动器振动是汽车工业中NVH（噪声、振动粗糙度）问题的典型例子。 汽车制动器开发过程的成本目前主要由NVH行为方面的优化决定。该项目的目的是优化制动器的平稳性和平稳性，即通过使用故意引入的阻尼，与噪音相反，显示振动和粗糙。该项目旨在模拟制动器中不同阻尼资源的影响，特别是集中在阻尼器上。这种装置特别用于汽车盘式制动器，以抑制尖叫声。但到目前为止，对工作原理的理解以及建模的艺术状态非常薄弱。该项目的目的是实验研究和模拟的行为。这些模型被引入到大型有限元代码完整的制动器和整个系统的稳定性行为进行了研究。
