虽然对制动器尖叫声的研究已超过一个多世纪,但仍未找到有效对它抑制的方法。科学界一致认为尖叫声是由于转子模式和衬片模式的耦合造成的,商业制动器的复杂性表明有效解决这个问题的设计方面的障碍。为此,一些研究人员着重于显示类似不稳定性的杆与盘的研究。本文基于伪消声原理推荐一种被动消声器,对杆与盘完全抑制尖叫声的发生。 Although the study of brake squeal has been more than a century, but no effective way to suppress it. The scientific community agreed that the screams were caused by the coupling of the rotor pattern and the lining pattern, and the complexity of commercial brakes has shown an obstacle in designing effectively to solve this problem. To this end, some researchers have focused on the study of rods and disks showing similar instability. In this paper, we propose a passive muffler based on the principle of pseudo-muffling to completely suppress the occurrence of screaming on the pole and the disk.
