Numerical Simulation Analysis for the Influence of Ageing on the Viscoelastic Damping Materials

  • Using the finite element analysis( FEM) numerical simulation software of PANTRAN/NASTRAN,the vibration levels of the stand treated with certain type of viscoelastic damping materials of unaged and used for 10 years were analysed.According to the results,the vibration acceleration levels of the materials of unaged and used for 10 years changed for about 5d B in the frequency range of 0—500 Hz and the vibration levels change for about 10 d B when the frequency was lower than 300 Hz.
