Numerical Simulation for Vibration-isolating Effect of Two Vibration-isolating Slots

Xiudi Li

Abstract

This paper makes some numerical simulations about vibration-isolating effect of two vibration-isolating slot and compares the vibration-isolating effect of single vibration-isolating slot with that of two vibration-isolating slots by taking advantages of ANSYS/LS-DYNA3D.Some relative cases of two vibration-isolating slots are analyzed.It is suggested that the vibration-isolating effect of two vibration-isolating slots is better than the single in the case of same digging.And the vibration-isolating effect can be improved by making the distance between two vibration-isolating slots and setting the deeper before.
