Abstract

Purpose

The contact and lubrication performances, which were previously estimated assuming a Gaussian surface, are insufficient due to the non-Gaussian surface characteristics of the honing liner. The purpose of this study is to analyze the liner honing surface and examine its effects on the contact and flow performance.

Design/methodology/approach

The fast Fourier transform (FFT) method was used to generate the liner honing texture. Subsequently, an elastoplastic contact model based on boundary element theory was constructed and simulated for the honing surface. The results were compared with those obtained using a Gaussian surface. In addition, flow factors of the honing surfaces were also compared.

Findings

The contact pressure and flow factors demonstrate significant disparities when dealing with non-Gaussian surfaces. In the deterministic model, the pressure exhibits considerably diminished magnitudes and a more evenly distribution. Moreover, when the gap between surfaces is narrow, the discrepancy in flow factor across different directions on the real honing surface becomes more prominent compared with the Gaussian surface.

Originality/value

The model incorporates the influence of the non-Gaussian honing surface, thereby enabling more accurate prediction.

非高斯珩磨表面对接触和流动特性影响的研究

目的由于珩磨衬垫的非高斯表面特征，以前假设高斯表面估计的接触和润滑性能是不够的。本研究旨在分析衬板珩磨表面，并研究其对接触和流动性能的影响。设计/方法/途径采用快速傅立叶变换（FFT）方法生成衬板珩磨纹理。随后，根据边界元理论构建了弹塑性接触模型，并对珩磨表面进行了模拟。模拟结果与使用高斯表面得到的结果进行了比较。研究结果在处理非高斯表面时，接触压力和流动因子表现出显著差异。在确定性模型中，压力的大小大大减小，分布更加均匀。此外，当表面之间的间隙较窄时，与高斯表面相比，实际珩磨表面上不同方向的流动因子差异会变得更加突出。原创性/价值该模型考虑到了非高斯珩磨表面的影响，因此能够进行更准确的预测。同行评议本文的同行评议记录可在以下网址查阅：https://publons.com/publon/10.1108/ILT-07-2023-0198/。
