VIBRATION
ABSORPTION
FOR FLEXIBLE LINKAGES UNDER
THE IMPULSE EXCITATIONS*
Abstract: A vibration absorber for the suspending beam subjected to the impulse excitation has been developed following the suppose, which is for solving the problems of vibration existed in the systems like the robotics and gun. The isolation and absorption theory for the vibration of the rigid bodies and the elastic beams have been employed and developed to analyze the absorber after simplifying the excitations exerted on the beam, the vibration absorption principles are expressed in terms of waves of propagating so that the design of absorber can be proceeded by analysis of the transmission and reflection coefficients matrices. The form and structure of the absorber, the design method based on the experiments, and the nonlinearity of the absorber have also been discussed. The test and experiment of the isolation vibration show the effectiveness of the new equipment. The vibration absorber is a solution to the vibration at the end of the beam subjected to the impulse excitation.
