在制动器噪音研究领域已被工程师们和科学家们普遍公认,盘式制动器的尖叫声起因于因摩擦力导致自激振动造成不稳定性,自激系统当时发生振荡,达到极限周波。Papp等在2002年基于一个十分简单的模型阐述了摩擦力实际工作(即尖叫声的激励)的先决条件。本文作者为激励机理起因的研究采用-多自由度系统,用观测的衬片上的平均摩擦力功率和典型稳定分析相比较,基于这些理论研究开发了一测量技术探测抑制尖叫声的参量的范围(例如,对制动压力和相当的尖叫频率)。
It has been generally accepted by engineers and scientists in the field of brake noise research that the screams of the disc brakes are caused by the instability caused by the self-excited vibration caused by the friction force. The self-excitation system then oscillates and reaches the limit cycle. In 2002, Papp et al. Described the preconditions for the actual work of friction (the screaming stimulus) based on a very simple model. The authors used a multi-degree-of-freedom system to study the causes of excitation mechanisms. Based on these theories, a measurement technique was developed to detect the range of parameters that suppress the squeal, using the average frictional power on the observed linings (For example, brake pressure and equivalent screaming frequency).
