摘要

在列车制动盘表面加工出不同角度分布的沟槽,探究带沟槽的制动盘表面对界面摩擦学行为和振动噪声特性的影响。结果表明:本研究中选取不同角度分布的沟槽都能在一定程度上提高制动盘材料的摩擦磨损特性并降低界面摩擦噪声,其中45°角度分布的沟槽降噪效果最佳。进一步的,利用有限元分析软件ABAQUS对试验结果进行数值模拟分析,结果表明沟槽的存在可以打断、分散接触界面的应力分布并对接触应力进行重新排布,从而抑制摩擦尖叫噪声的产生。

Abstract

An experimental study was performed to investigate the effect of grooved brake disc on the tribological behaviors and friction-induced vibration and noise characteristics. The test results show that every kind of the grooved disc samples has good potential in improving the friction and wear behaviors of the interface, and cutting 45° grooves on the disc surface can significantly reduce the friction noise. Moreover, a numerical analysis was performed to simulate the experimental process by using the finite element software ABAQUS. It is found that the grooved discs can significantly disturb the contact pressure distribution on the pad surface and consequently reduce the squeal.
