在橡胶制品的设计和开发中，评估摩擦系数对接触载荷的依赖性是很重要的。特别地，由于压力分布根据滑动体的尺寸和接触表面的图案而变化，因此期望能够考虑这些影响的简化且准确的评估方法。在这项研究中，我们提出了一种预测方法，橡胶试样之间的任意形状的任意粗糙度和光滑的硬表面之间的粘附摩擦，通过结合：（1）考虑粗糙度的影响的摩擦理论;（2）基本的摩擦测试;（3）有限元分析。此外，我们验证了所提出的方法的有效性，通过比较的预测结果与测量结果之间的半球形PDMS试样和PMMA平板和PDMS块试样与凹槽表面和平面棱镜之间的摩擦。结果表明，预测精度的摩擦系数的接触载荷依赖性是相当不错的。
In the design and development of rubber products, it is important to evaluate the contact load dependency of the friction coefficient. In particular, since the pressure distribution varies depending on the dimensions of sliding bodies and the pattern of the contact surface, a simplified and accurate evaluation method that can take these influences into account is desired. In this study, we proposed a prediction method for the adhesive friction between rubber specimens of arbitrary shapes with arbitrary roughness and a smooth hard surface, by combining the: (1) friction theory considering the influence of roughness; (2) basic friction test; and (3) finite element analysis. Further, we verified the effectiveness of the proposed method by comparing the predicted results with the measurement results of friction between a hemispherical PDMS specimen and a PMMA flat plate and between a PDMS block specimen with a grooved surface and a flat prism. Results show that the prediction accuracy of the contact load dependency of the friction coefficient is reasonably good.
