Investigation on the Mitigation Effects of a New Vibration Isolation Module
With the development of urban traffic in China , it has brought us lots of convenience , meanwhile ,it also can cause the environmental vibration. The paper presents the new vibration isolation module(patent number;ZL 2010 2 0147603. 1). Firstly,taking the soil vertical displacement into account and ignoring the radial displacement ,the dynamic equilibrium equation of pile and soil is established according to the principle of active vibration isolation under the 3d axisymmetric soil model condition. And then the displacements and stresses of radial inhomogeneous layers can be ob — tained, when the vertical concentrated harmonic load is applied on the pile top. Considering the continuity conditions between the layers and the boundary conditions of soil and pile ,the unknown coefficients in the expressions can be determined , and the analytical response solutions in frequency do -main is presented. Finally,each important parameter of influence on the the effectiveness of isolating vibration is discussed and optimized.
