填料和纤维配比对摩擦材料摩擦磨损性能影响
|
摘要
制备填料和纤维组分含量不同的两种摩擦材料,通过变速变压实验分析不同配比对摩擦材料摩擦磨损性能的影响规律,为摩擦材料的研发提供理论依据。利用X-DM调压变速试验机在不同温度、不同压力、不同转速下进行摩擦磨损试验,比较两种摩擦材料摩擦因数和磨损失重的差异,并用正交表分析两种材料对温度、压力和转速变化的敏感度。结果表明,含增摩填料较多的摩擦材料摩擦因数低,摩擦因数稳定性好,磨损大且对温度变化敏感,适合在低温工况下使用;含增强纤维较多的摩擦材料摩擦因数高,磨损小且磨损稳定,适合在中高温工况下使用。
Two kinds of friction materials with different contents of fillers and fibers were prepared. The effects of different ratios on the friction and wear properties of friction materials were analyzed through variable speed and variable pressure experiments, which could provide theoretical basis for the development of friction materials. The friction and wear experiments were carried out on the X-DM variable-speed pressure-regulating test machine at different temperatures, pressures and speeds. The differences in friction coefficients and wear weightlessness between the two friction materials were compared. The sensitivity of the two materials to temperature, pressure and speed changes was analyzed by orthogonal table. The results show that the friction material with more friction-increasing fillers has low friction coefficient, good stability of friction coefficient, large wear and sensitivity to temperature change, and is suitable for use at low temperature. The friction material with more reinforced fibers has high friction coefficient, small wear and stable wear, and is suitable for use at medium and high temperature.
