Abstract
This paper accurately predicts and quantifies the vibration response characteristics of a mirror bender system with the finite element simulation and experiment. The results show that the fundamental frequency of the roll angle vibration is 24.66Hz, and the fundamental frequency of the pitch angle vibrationis 116.21Hz. The overall error is within 11.15% in comparision with the first six natural frequencies obtained from experiments and simulations. The vertical support rod, being one of the weakest links in the overall structural stiffness, is a crucial factor limiting the increase in the natural frequency of the mirror system. Before and after the injection of cooling water, the pitch angle vibration was 123.63 and 199.04 nrad, respectively. An increase in the cooling water flow rate from 1 to 1.5 l/min has almost no effect on pitch angle vibrations. This study provides references and guidance for improving the stability of the mirror system.
