【Abstract】 Friction has a significant effect, even dominant one in some cases, on the dynamic behavior of mechanical systems. Thorough investigation on friction dynamics is very important to avoid negative influences of friction on dynamical systems and make reasonable use of its beneficial effect. This paper outlines recent advances in the research of friction dynamics in mechanical systems. The friction model in common use, researches on the friction related self-excited, forced vibration and vibration control are presented. Besides the research methods, investigations on applications of friction dynamics are emphatically discussed, including the braking noise vibration, vibration energy dissipation and friction vibration control in a variety of fields.更多还原
