Design And Study Of The Non-Uniform Speed Friction&Wearing Testing System

Study of tribology has great social and economical significance. Friction and wearing is a long time process which is very complex. The classical friction and wearing theory deems that the change of friction speed would alter friction only slightly, so, the influence of changing friction speed on friction is always neglected in the traditional study.Although the change of friction speed influence friction little on it's numerical value, a continued and periodical change of friction speed can result in the deterioration of friction condition. The accumulation of this deterioration will induce some kinds of failure of friction couples, such as fatigue failure.The most powerful tool of tribology study is experiment and all kinds of friction testing system is designed and manufactured for friction test. But at present, none of these friction testing systems can change friction speed continuously and real-timely. For the sake of validating the influence of changing friction speed on friction and wearing state, and also for study the friction couples materials'...
