摘要： 为研究碳刷研磨装置的研磨精度，以自主研制的碳刷研磨装置为平台，基于Archard模型构建了碳刷研磨成形去除模型，并得到了碳刷研磨成形去除率预测公式，从而获得了横、纵向所需去除长度不同的碳刷的研磨次数。然后，基于所研制的碳刷研磨装置，开展了碳刷研磨成形正交实验以及碳刷研磨成形去除模型验证实验。结果表明，对碳刷研磨成形效果产生影响的因素按影响程度从大到小排序，依次为压下弹簧弹性系数、砂纸目数、砂轮步进电机脉冲频率；基于建立的去除率预测公式所获得的碳刷研磨次数较为准确，可保证碳刷的研磨效率。研究结果为不同型号碳刷研磨装置的进一步研发提供了理论指导和实验依据。
Abstract: In order to study the grinding accuracy of the carbon brush grinding device, taking the self-developed carbon brush grinding device as the platform, the carbon brush grinding and forming removal model was constructed based on the Archard model, and the prediction formula of carbon brush grinding and forming removal rate was obtained, so as to obtain the grinding times of carbon brushes with different removal lengths in the transverse and longitudinal directions. Then, based on the developed carbon brush grinding device, the orthogonal experiment of carbon brush grinding and forming and the verification experiment of carbon brush grinding and forming removal model were carried out. The results showed that the factors affecting the grinding and forming effect of carbon brush were sorted in descending order of the influence degree, followed by the elastic coefficient of compression spring, the mesh number of sandpaper and the pulse frequency of grinding wheel stepping motor; the carbon brush grinding times obtained based on the established removal rate prediction formula were more accurate, which could ensure the grinding efficiency of carbon brushes. The research results provide theoretical guidance and experimental basis for the further development of different types of carbon brush grinding devices.
