建立了一种新的二维模型，应用热-应力耦合场，通过有限元分析揭示了多孔PEEK复合材料的自润滑过程及孔隙率对摩擦学性能的影响。结果表明，采用热-应力耦合场分析方法，可以准确地计算出温度、位移和应力的数值分布。多孔PEEK复合材料的孔隙率是其自润滑性能的关键。通过实验验证，模拟结果与实验结果基本一致，最大误差小于7%。热-应力耦合场有限元分析是研究多孔聚合物复合材料自润滑性能的有效方法。
A novel two-dimensional (2D) model was developed and heat-stress coupled field was applied to reveal the self-lubricating process and effects of porosity on tribological properties of porous PEEK composites by finite element (FE) analysis. Results indicated that the numerical distributions of temperature, displacement and stress were accurately calculated by using heat-stress coupled field analysis. Porosity was crucial for the self-lubricating properties of porous PEEK composites. By experimental verification, the simulated results were consistent with the experimental results with the maximal errors less than 7%. The FE analysis using heat-stress coupled field was effective to study the self-lubricating behaviors of porous polymer composites.
