Simulation of a rubber isolator with three-dimensional vibration reduction characteristics

Abstract

A new kind of rubber Isolator is proposed in this paper. Rubber and metal are combined to form an hour-glass shaped vibration control cell and the cell is arrayed form a vibration damping sheet. The finite element method is used to simulate the random vibration response of the electronic equipment and vibration damping sheet system. By using this method, the transmission curves, deformation and equivalent stress of the vibration damping sheet driven by the random vibration are obtained. It is found that this new sheet can satisfy the requirement of reducing vibration of the electronic equipment with broadband, multi-direction, lightweight, small deformation characteristics. It also has strong practicality and expansibility for other box structure with strong random vibration excitation.
