From the results of the past experiments, it is reported that the friction force and coefficient of frictional isolators are strongly dependent on the sliding velocity and pressure.In addition to them, the temperature is also the important factor for the property of materials.In this study, based on the tribology theory, a numerical model for frictional isolators, which consist of PTFE and SUS, is proposed. Compared with the experimental results of the shaking table tests, it is found that the model can simulate well the behavior of frictional isolators under variational normal pressure, sliding velocity and displacement.
