The Effect of Shape Factor on the Operation Periods of Anti-Vibration Rubber

Abstract

This research aims to study the shape factor affects on the rubber that resistant to the vibration. Three different shapes of rubber mounts(cylindrical , hexagonal and trapezoidal shapes)having the same volume was prepared. The anti-vibration models was manufactured depended on the pre-selected recipes according to specific specifications suitable for this purpose. In this work, actual application test in AL-Kufa cement factory was done to get knowledge about the efficiency of the manufacturing mounts. Furthermore, simulation for the three above  models  by ANSYS V.11 Program was done. The actual application result shows that, hexagonal model is the best because the higher operation periods while the simulation shows that ,there is a decreasing in the stress intensity of the hexagonal shape, this may be explain why it has longest operation period than the other two shapes.
