摘要：

聚合物材料滚动摩擦时，其独特的黏弹性质使其弹性滞后效应比其它材料显著得多。为探索弹性滞后效应对聚合物滚动摩擦阻力的影响规律，利用电磁加载的新型斜面法考察了聚四氟乙烯（PTFE）、聚甲基丙烯酸甲酯（PMMA）、聚醚型聚氨酯（PEUR）等工程塑料与淬火45#钢配副时的滚动摩擦阻力，利用CETR UMT-2型试验机考察了PTFE，PMMA，PEUR的蠕变、松驰行为。基于标准线性固体模型，从弹性滞后效应的角度推导了聚合物滚动摩擦阻力的表达式，对比分析了实验数据和模拟计算结果。结果表明：同样实验条件下，PEUR的滚动摩擦阻力最大，PTFE次之，PMMA最小，三者的比值约为1：0.51：0.28。模拟计算结果与实验数据基本吻合，可以说明弹性滞后效应是聚合物滚动过程中摩擦阻抗的主要来源。研究结论为从黏弹性角度研究聚合物的滚动摩擦行为提供了一条新的途径。

Abstract:

Owning to the unique viscoelastic properties, the elastic hysteresis effect of polymer materials is much greater than that of other materials in the rolling friction. In order to explore the influence rule of elastic hysteresis effect on rolling friction force of polymer materials, a new inclined plane method using electromagnetic loading was adopted to evaluate the rolling friction force between engineering polymer like PTFE, PMMA, PEUR and hardened 45# steel. In addition, the creep and relaxation behaviors of PTFE, PMMA and PEUR were investigated by CETR UMT-2 equipment. Based on the standard linear solid model, the expressions of rolling friction force were derived in terms of the elastic hysteresis effect, and the experimental data and simulation results were compared and analyzed as well. The results showed that the rolling friction force decreased in order of PEUR, PTFE and PMMA with the ratio of about 1:0.51:0.28 under the same experimental conditions. The simulation results were in good agreement with the experimental data, which indicated that the elastic hysteresis effect was the main source of friction resistance in polymer rolling process. Moreover, the conclusion of this research has explored a new approach for studying the rolling friction behavior of polymer from the view of viscoelasticity.
