Development of gel-structured electro-rheological fluids and their application to mechanical damper elements

摘要

Electrorheological fluids (ERF) are functional fluids whose viscoelastic property varies according to the intensity of the applied electric field. The disadvantages of ERF are the sedimentation of ER particles and the requirement of seal mechanism. In order to solve these problems, gel structured electrorheological fluids ERF are developed in this study. The basic characteristics of ERF film is experimentally analyzed. Based on the results of basic analysis, the ERF was applied to the mechanical damper elements.
