| Abstract: | Casting polyurethane material has good dynamic performance. In this paper, through the testing of the polyurethane material specimen, and the testing and the numerical simulation of the vibration isolators made of this material, the allowable stress of the polyurethane material is determined. On this base, a polyurethane vibration isolator which is able to bear 300kN loading is developed, and its first intrinsic frequency is found to be lower than 5Hz. |

| Keywords: | vibration and wave high loading isolator polyurethane anti-vibration |
