Vibration reduction and energy harvesting were achieved by installing a piezoelectric cantilever beam (PZT-beam). Experimental work was carried out on a self-developed tribology and dynamic behavior simulation test device. Finite element (FE) model and numerical simulation model were established to analyze the effect of the PZT-beam on the dynamical response, system stability and the vibration energy harvesting performance of the brake system. The experimental and simulation results show that friction-induced vibration (FIV) can be reduced via a PZT-beam, and the vibration energy can be converted into electrical energy through the deformation of the PZT-beam. The PZT-beam can significantly reduce the real part of the complex eigenvalues of the brake system without significantly changing the unstable vibration frequency and mode shape.

通过安装压电悬臂梁 (PZT 梁) 实现了减振和能量收集。在自行研制的摩擦学和动态行为模拟试验装置上进行了实验工作。建立有限元（FE）模型和数值模拟模型，分析PZT梁对制动系统动力响应、系统稳定性和振动能量收集性能的影响。实验和仿真结果表明，PZT梁可以减少摩擦引起的振动（FIV），并且可以通过PZT梁的变形将振动能量转换为电能。PZT 梁可以显着减少制动系统复特征值的实部，而不会显着改变不稳定的振动频率和振型。
