摘要

用脉冲磁场处理对含高达 20 wt % 分散铜的聚合物摩擦复合材料的三声特性的影响。研究表明,在各种物理和机械特性中,动态机械特性对复合材料成分混合物的磁场处理具有显著的统计学响应。研究发现,在磁场强度为 20 kA/m 的单极和双极模式下,对复合材料的初始混合物进行磁处理,可使静摩擦系数和动摩擦系数之差减少 3.0-3.4 倍,而磨损率和制动效率损失在统计上没有明显变化。实验证实,摩擦时的声压级在 2 kHz 以上的频率范围内降低了 23-24 dB。

Effect of Treatment in a Magnetic Field on the Triboacoustic Characteristics of Copper-Containing Polymer Friction Composites

The effect of treatment with a pulsed magnetic field on the triboacoustic characteristics of polymer friction composites containing up to 20 wt % dispersed copper. It has been shown that among various physical and mechanical properties, a statistically significant response to magnetic field treatment of a mixture of composite components is demonstrated by dynamic mechanical characteristics. It was found that magnetic treatment of initial mixtures of composites in both unipolar and bipolar modes with a field strength of 20 kA/m leads to a decrease in the difference between the coefficients of static and dynamic friction by 3.0—3.4 times without a statistically significant change in the wear rate and loss of braking efficiency. A reduction in sound pressure levels during friction by 23–24 dB in the frequency range above 2 kHz has been experimentally confirmed.
