Abstract: Effects of reinforcing layer thickness, Young's modulus and damping of connection joints on the vibration reduction of composite stand are investigated in numerical simulation methods. The results indicates that increasing reinforcing layer thickness or reducing Young's modulus favors the vibration reduction performance of composite stand, while vibration reduction is not affected obviously by increasing the connection joints damping. A vibration experiment with a selected typical connection form stand revealed that the values of insertion loss of experiment are almost consistent with simulation calculated value, which verified the correctness of simulation results.
