为探究制动片关键参数对制动系统动力学特性的影响,基于滑块-转盘结构的摩擦试验机展开试验研究。试验研究制动片关键参数(转速、压力、质量、制动半径等)及制动环境(干摩擦、湿润、泥沙)对制动系统稳定性的影响。同时,建立制动片制动系统动力学模型,利用自相关系数这一数学工具和试验结果进行对比。结果表明,制动片关键参数对制动系统动力学特性有明显影响;在不同的制动片质量、摩擦学参数、制动片半径、制动环境的情况下,制动摩擦力信号的混沌特性出现扩大或缩小的趋势,可以通过调整制动片关键参数来抑制混沌振动。该研究可以为制动片系统的制动策略优化与降噪抑振提供一定参考。
To explore the impact of key parameters of brake pads on the dynamics characteristics of the braking system
the test research based on a friction testing machine with a slider-disc structure was conducted.The test research of the impact of key parameters of brake pads (rotation speed
pressure
mass
braking radius
etc.) and the braking environment (dry friction
wetness
sand) on the stability of the braking system was carried out. At the same time
a dynamics model of the brake pad braking system was established,compared with test results using the mathematical tool of autocorrelation coefficient. The results show that the key parameters of brake pads have a significant impact on the dynamics characteristics of the braking system; under different conditions of brake pad mass
tribological parameters
brake pad radius
and braking environment; the chaotic characteristics of the braking friction force signal show a trend of expansion or contraction; the chaotic vibration can be suppressed by adjusting the key parameters of brake pads. This study can provide reference for optimizing the braking strategy and reducing noise and vibration in brake pad systems.
