高速摆动条件下PTFE编织复合材料干摩擦热行为研究
Study on Friction Thermal Behavior of PTFE Braided Composites Under High-speed Oscillating Conditions
摘要
Abstract
The dry friction test of polytetrafluoroethene (PTFE) braided composites under high-speed Oscillating conditions has been carried out on the special high-speed tribo machine and 9Crl8Mo as counterpart, the influences and the variation rules of friction heat has been studied. Results show that friction temperature increases with the increasing of load; and the temperature decreases with increases in frequency of short duration in the initial friction stage, later increases with increased frequency, and finally reach temperature dynamic balance; the friction coefficient rises slowly in small range before a sharply reduces with the increase in time, ultimately,it maintains a relatively stable state, and has certain corresponding relationship with friction temperature; The main abrasion mechanism of friction pair is adhesive wear, and temperature is an important factor that influences friction process and the wear mechanism.关键词
