刹车尖叫仍然是设计工程师和科学家的一个挑战。由于避免制动噪声的成本原因，对于广泛的工业范围，只有被动措施才有意义。许多针对尖叫声的对策都是基于阻尼的引入，例如使用阻尼器。在制动尖叫建模的文献中，制动盘的结构特性通常不被考虑。然而，分析和实验表明，圆盘的刚度特性是重要的，并且圆盘的双模式的分裂具有稳定效果。这些知识可用于制动转子的结构优化。本文的目的是开发潜力，并讨论一些数学困难。此外，转子的不对称性和尖叫的关系的实验证据。
Brake squeal is still a challenge for design engineers and scientists. Due to cost reasons for the avoidance of brake noise only passive measures are meaningful for a broad industrial range. Many countermeasures against squeal are based on the introduction of damping, for example by using shims. In the literature on the modeling of brake squeal, the structural properties of the brake disc are most often not considered. It has however been shown analytically and experimentally that the stiffness properties of the disc are important and that splitting of double modes of the disc has a stabilizing effect. This knowledge can be used for structural optimization of brake rotors. The goal of this paper is to exploit the potential and to discuss some mathematical difficulties. Furthermore, experimental evidence for the relation of rotor asymmetry and squeal is given.
