基于新型斜面法的聚合物滚动摩擦阻力研究
Research on rolling friction force of polymer based on new inclined plane method
摘要
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 addi-tion ,the creep and relaxation behaviors of PTFE ,PMM A and PEUR were investigated by CETR UM T-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 simula-tion 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 experi-mental data ,which indicated that the elastic hysteresis effect was the main source of friction re -sistance 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 .关键词
