The fly mechanism and motion characteristics of the birds were analyzed. By the bionics principle, a new bionic flapping wing mechanism was proposed in order to imitate the motion of bird wing. The virtual prototype of this mechanism was established through ADAMS, then the kinematic simulation analysis was applied to the prototype in order to validate the feasibility of this mechanism. And a computational fluid dynamics software, named Fluent was employed to analyze the aerodynamic force of bionic wing. These results shorten the period of manufacturing of flapping wing mechanism, and can provide theoretical basis for the research and manufacture of bionic flapping wing robot.

This paper summarizes vibration control methods in the process of machining, and the current research progresses, in view of the difference in vibration control technologies and methods, from several aspects such as the eliminating vibration control technology, the isolating vibration control technology, and absorbing vibration control technology, etc .Simultaneously with the continuous improvement of the traditional control method, the organic combination the new material technology and intelligent control methods will also be the future trend of development.
