摘要:
在传统摩擦材料中引入导热层,在保证制动效果的前提下,既降低了材料的摩擦热,又提高了材料的性能。采用MPX-2000型磨损试验机和有限元模拟考察双层摩擦材料不同导热层厚度(1.5、3.0、4.5、6.0和7.5 mm)与不同导热系数(2、4、6、8 和10 W/(m·K))对表面最高温度的影响,利用扫描电子显微镜(SEM)对摩擦材料的磨损表面形貌进行分析。结果表明:引入导热层后,摩擦表面最高温度(18 ℃)和磨损率(29.6%)均降低。同时研究发现,增加导热层厚度摩擦材料的接触面温度降低,导热层厚度越大,导热系数影响的效果越明显。
Abstract:
To ensure the brake performance,a heat-conductive layer was added to traditional friction materials, it accelerated heat transfer and improved the performance of the friction materials.The MPX-2000 friction tester and the finite element method were used to investigate the effects of heat-conductive layer thicknesses(1.5,3.0,4.5,6.0 and 7.5 mm)and thermal conductivity(2,4,6,8 and 10 W/(m·K))of double-layer friction materials.The friction surface was characterized by scanning electron microscope(SEM).Results showed that the friction materials with heat-conductive layer decreased the maximum contact temperature(18 ℃)and wear rate(29.6%).The increase of the thickness of heat-conductive layer decreased the contact temperature.The thicker the heat-conductive layer was,the greater the influence of the thermal conductivity was.
