Abstract
Colloidal damper is a new damper which uses a principle of difference of surface extension force, which is occurred by the direction of movement of surface. Some characteristics of the colloidal damper were investigated by our group. That is, a damping characteristics of colloidal damper for the amount ratio of silica gel and water, volume of cylinder and pre-pressure of the cylinder by changing exciting frequency and displacement of a piston. By using these results, this paper presents a design method of the colloidal damper, that is, diameter and length of a cylinder, pre-pressure in the cylinder, ratio of silica-gel and water. In order to show a flow of this design method, suspension of car which is composed by colloidal damper and spring, is presented.
