This paper mainly focus on vibration friction and discuss the dynamic characteristics of the friction under the vibration working condition. It is rather valuable to study such a special kind of friction vibration in engineering. Many practical projects have already proved that under the vibration working condition, the friction force between workpieces can be reduced obviously. Wear and damage of the machine parts can be obviously decreaed.The work efficiency can be improved greatly. The Characteristic of friction under the vibration working condition is described in the paper firstly. Two fundamental experiments illustrate the basic features of vibration friction. With the nonlinear dynamics and tribology of vibration friction, some key machinery is introduced in the paper briefly. The study of vibration tribology is attracting more and more interest of investigators.
