摘要：
Considering the severe brake squeal noise generated at the brake pad/disc interface when the train brakes at low running speed, elastic damping shims and piezoelectric elements are designed into a sandwich-like damping aiming at reducing the brake squeal noise and harvesting energy from the friction-induced vibrations simultaneously. Braking tribology tests are performed using the self-developed high-speed train brake dynameter, meanwhile wear and transient dynamic analysis are conducted through finite element method. The influences of the sandwich damping on the surface wear of the friction block and the contact behavior at the brake interface, as well as the output voltage are comprehensively studied. The results indicate that the sandwich damping can effectively reduce the brake squeal noise due to its damping characteristics, meanwhile, significant voltage signal is detected during the brake process, indicating the satisfactory energy conversion performance of the sandwich damping. Based on the experiments and the finite element simulations, it is found that the damping shims can significantly reduce the eccentric wear of the friction block, thereby improving the contact behavior at the brake interface and reducing friction thermal concentration. The flexible damping shims can modify the contact state between the brake disc and friction block in real time, resulting in uniform wear on the pad surface. Therefore, the friction-induced vibration of the brake system is reduced. © 2024 Chinese Mechanical Engineering Society. All rights reserved.
