摘要
探讨了丁腈橡胶在三元复合驱液中的摩擦过程特征、材料匹配性的影响和橡胶变形量对摩擦副启动摩擦阻力的影响。研究表明,三元复合驱液良好的润滑性能改善了橡胶的摩擦性能,但改善的摩擦性能未达到消除摩擦弹性滞后的程度,且三元复合驱液对橡胶的疲劳寿命影响很大;作为具有弹性性能的橡胶体,其与摩擦副间的启动摩擦阻力因数随初始变形量的增加而增大,但当其处于匀速摩擦时,其摩擦过程虽然也反映出自身的周期波动特点,但其平均摩擦因数处于稳定状态,且反映了介质的润滑性能。
The frictional characters, the influence of material compatibility, the effect of NBR deformation on the starting frictional drag of friction pairs used in ASP flooding are investigated. The study indicates that good lubrication of ASP flooding improves the friction performance of NBR, but it is not to the extent of eliminating the friction elastic hysteresis,the influence of ASP flooding on NBR fatigue life is severe, but when it is in even friction, its average friction factors is stable and reflects the lubrication performance of medium, although its cyclic fluctuation of itself is reflected in the friction process.
