摘要

利用定制试验装置，研究圆形双摩擦块不同相对位置分布对制动系统摩擦学行为和动力学行为的影响，并采用有限元方法分析了摩擦块表面接触应力分布特点，探讨了不同相对位置分布与界面接触行为、摩擦磨损以及stick-slip振动之间的关联。综合试验结果和仿真分析结果表明：双摩擦块制动系统不同相对位置分布显著影响了制动系统界面接触压力分布及摩擦块表面磨损特性，使系统产生不同形式的stick-slip振动。在本试验下，沿摩擦盘径向分布的两个摩擦块表面磨损轻微，接触压力分布相对均匀和具有较小的stick-slip振动幅度。因此，合理的设计摩擦块间的排布可以有效抑制盘块摩擦界面stick-slip振动，减轻摩擦块的磨损，减小系统部件振荡，从而提高摩擦系统稳定性。研究结果对汽车和火车（特别是高速列车）制动器的设计有较重要的参考价值。

Abstract

The influence of relative positions of two circular friction blocks on the tribological behaviour and dynamic characteristics of a simplified and customized experimental brake system of a pads-on-disc configuration was studied. The contact stress distribution characteristics of the friction blocks were analyzed by using the finite element method, and the relationship between different the relative positions and interface contact behaviour, friction and wear, and stick-slip vibration was discussed. The results of comprehensive test and simulation showed that the different relative positions of the two friction blocks significantly affect their interface contact pressure distribution and the wear characteristics, resulting in different forms of stick-slip vibration. It was found that the surface wear of the two friction blocks oriented along the disc radius is slight, the contact pressure is relatively evenly distributed and the stick-slip vibration intensity is low. It was also found that a sensible arrangement of friction blocks can effectively suppress the stick-slip vibration at the friction interface, mitigate wear of friction blocks, reduce the oscillation of system components, and improve the stability of the friction system. This work contributes to an improved design of brakes for automobiles and trains (in particular, high-speed trains).
