Abstract:

Aiming at the problem of periodic vibration load of rotating machinery under unbalanced condition，the metal rubber isolator model is designed which is suitable for periodic vibration of rotary machine according to the design principle of vibration isolator. The metal rubber block was prepared referring to the actual parameters of ZDT-2Y/2W-3 rotary vibration test-bed. Finally, a finite element analysis method based on ANSYS is developed for the identification of metal rubber materials under the vibration condition of the rotating machinery using orthotropic damping parameters, at the same time, evaluating the method according to the material fourth strength theory. The results show that the finite element simulation method can be applied to the vibration isolation of metal rubber under the unbalanced state of rotating machinery.
