%X In this paper,the secondary mirror vibration absorption,a effective way in some cases to control the primary mirror/secondary mirror vibration,is presented based on the studying on the vibration of the structure of large optical system.And the vibration suppression effect on the secondary mirror under a wider frequency range excitation is analysed and the damping ratio is a decisive factor.Then the optimal design of the structure of a vibation absorber is presented.The absolute amplitudes nondimensional response of the secondary mirror with a vibration absorber is just one 6th of the absolute amplitudes nondimensional response of the secondary mirror without vibration absorber under the same excitation (0.1g shock).
