Abstract: Based on comprehensively and systematically study and analysis of eight-bar linkage vibration mechanism, a new theory and method is presented to study and analyze the vibration mechanism. The properties of vibration are calculated. This presentation provides a theoretical base for study and redesigning the mechanical vibration system. A numerical solution as an example of a high vibration mechanism is gave. The validity of the theories and method presented is verified. This method is also suitable for other mechanical equipment's vibration character.

Key words: Model analysis, Oscillation response, Vibration characteristics, Vibration mechanism
