Abstract:A finite element simulation method of random vibration for metal rubber damper was put forward. The orthotropic anisotropy damping material was used to simulate metal rubber, and the related simulation parameters were determined through the sine sweep experiments of the metal rubber damper. The finite element simulation of metal rubber damper random vibration was done via ANSYS Workbench. Simulation results was compared with the experimental ones. Results show that the proposed finite element simulation method can well simulate metal rubber damper random vibration and the calculation results with high accuracy.

Key words: metal rubber damper;random vibration;finite element simulation; orthotropic anisotropy damping material
