Test on the Vibration Isolation Efficiency of Spring Vibration Isolated Turbine-Generator Foundation

Abstract:

For the defects of simplified calculation method of vibration isolation efficiency to the spring vibration isolation foundation. In this paper a test method of vibration isolation efficiency was proposed.Through building a 1:8 model of spring vibration isolated turbine-generator foundation, this paper study the vibration isolation efficiency by measuring the acceleration.The test results and the simplified calculation’s results were slightly different as the latter ignoring the influence of high modes.The test results show that the test method is feasible.
