Analysis about Isolation Floor Consisting of FPS System and Dish Spring

Article Preview

Abstract:

A theoretical analyzing approach about the compound floor isolation system consisting of FPS and dish spring is derived. It starts from the Lagrange equation, with the coupling effect of the horizontal vibration and vertical vibration being included. Computation results show that for the proper specifications the floor isolation system may exhibit good effectiveness in mitigating the acceleration of the unfixed objects or equipments in both horizontal and vertical direction, while the extra displacement could be limited to be in a manageable range. The expected parameters for mitigating the accelerations agree with that for displacements in a partial domain. The specification of a floor isolation system needs low friction coefficient on the slide 0.05<μ<0.1, a reasonable slide radius 0.5<μ<1.0m, a relatively low stiffness coefficient and relatively high damp coefficient of the dish spring.
