导磁制动副摩擦磁化行为及机理研究

Friction Induced Magnetization Behavior and Mechanism of Magnetic Conductive Brake Pair

  • 摘要: 利用盘式制动器模拟制动试验台,研究了由磁性有机摩擦片与HT250制动盘构造的导磁制动副在制动过程中的摩擦诱导磁化行为,探讨了制动初速度和制动压力对摩擦磁化的影响规律及作用机理. 结果表明:制动初速度增大将会导致摩擦面温度升高,致使热退磁效应出现,进而使导磁制动副摩擦磁化感应强度减小,这是削弱摩擦磁化的主要因素;随着制动压力的增大,摩擦面温度略微增加但变化不大,但摩擦表面的摩擦磨损程度逐渐加剧,铁镍元素总含量明显上升,导致导磁制动副摩擦磁化磁感应强度增大,从而摩擦磁化获得增强. 研究结果不仅可以为磁控摩擦制动技术的发展提供理论支撑,也可为其他宏观机械和微纳系统界面摩擦磁化研究提供有益理论参考.

     

    Abstract: The friction induced magnetization (FIM) behavior of a magnetic conductive brake pair consisting of magnetic organic friction material and HT250 brake disc was studied on a simulated test bench of disc brake. The influencing laws and mechanisms of initial braking speed and braking pressure on the FIM were investigated and discussed by experiments. The results show that by increasing initial braking speed a significant rise of temperature on the friction surface was observed and thermal demagnetization effect reduced the magnetic induction intensity. The initial braking speed might be a major factor for reduced FIM. However, the surface temperature increased slightly with the increasing braking pressure. And the degree of wear damage increased gradually, which resulted in a significant increase of amount of elements iron and nickel on the worn surface. The magnetic induction intensity was then increased, indicating that the braking pressure may be of great significance for enhanced FIM. It is believed that the research can provide not only important theoretical basement for developing of magnetic field controlled braking technology, but also valuable reference for investigation of surface FIM in related macro machinery and micro-nano systems.
