The authors propose a micro-vibration isolation system composed of springs and viscous dampers. Application of isolation systems in highly seismic areas like Japan requires confirmation of seismic safety as well as isolation capability. The study on the seismic safety of this system was described in a previous paper. This paper deals with the isolation capability of this system to micro vibration. A series of excitation tests using an exciter, a steel ball dropping and a running truck are carried out. Finite element analyses by a dynamic substructure method is conducted. Through these tests and the analyses, the isolation capability of this system is clarified, and the accuracy of the dynamic substructure method for predicting vibration transmission loss is validated.
