摘要
以VL型径向唇形密封结构为研究对象,采用数值仿真和试验研究相结合的方法,基于多尺度分析聚四氟乙烯(PTFE)密封材料的宏观和微观摩擦特性。结果表明,磷酸酯液压油润滑的PTFE密封材料的摩擦力较干摩擦平均下降28.7%,在磷酸酯液压油润滑下PTFE密封材料的宏观和微观接触压力和摩擦功密度均随着温度的升高而减小。
Taking the VL radial lip seal structure as the research object,using a combination of numerical simulation and experimental research,the macro and micro friction characteristics of polytetrafluoroethylene(PTFE)sealing material was studied based on multi-scale analysis.The results showed that,the friction force of PTFE sealing material lubricated by phosphate ester hydraulic oil was 28.7%lower than that of dry friction on average.Under the lubrication of phosphate ester hydraulic oil,the macro and micro contact pressure and friction work density of PTFE sealing material decreased with the increase of temperature.
