【摘要】：采用大止推圈摩擦副,针对两个物体在相互摩擦过程中,材料配合的相互耦合摩擦现象进行实验研究。选取模糊聚类分析法建立计算模型,研究对摩两表面品质相似度与摩擦因数的关系。实验结果表明:两对摩表面品质的相似度与摩擦因数之间明显相关;在干摩擦试验各参数相同条件下,随着对摩表面品质相似度的增大其摩擦因数也增大。计算得到的表面相似度与摩擦因数Pearson相关性大于0.8,证明所提出的表面品质相似度计算模型的正确性。
[Abstract]:A large thrust ring friction pair is used to study the coupling friction phenomenon of two materials in the process of friction. The fuzzy cluster analysis method was selected to establish the calculation model, and the relationship between the similarity of surface quality and friction coefficient was studied. The experimental results show that the similarity between the surface quality of two pairs of friction is obviously related to the friction coefficient, and the friction coefficient increases with the increase of the similarity of the friction surface quality under the same conditions of dry friction test. The correlation between the surface similarity and the friction coefficient Pearson is greater than 0.8, which proves the correctness of the proposed surface quality similarity calculation model.
