Research Abstract

This research is development of a new damper which is used a principle of surface extension in a very small pore. The pore made of silica gel is coated by hydrophobic material. Then if water flows in and out to the pore, both surface extension forces are different. This difference induces energy dissipation, because the area made by tracks of the forces of flow in and out becomes dissipation energy. The object of this research is to select adequate coating material, pore diameter, pressure of water and liquid to design a proper damper system and application model by using experimental manner and to analyze movement of water in a pore by using molecular dynamics. In the experiment a damper is made by cylinder / piston system and colloidal liquid composed by hydrophobic silica gel and water. First, static test is performed to obtain basic characteristics of the colloidal damper and material for design of the damper is obtained. Second, dynamic test is performed by using an exciting machine and frequency response of the damper, that is, hysteresis characteristics due to frequency change and pre-pressure in the cylinder are investigated. Then the followings are concluded; (1) SMB70-20-MT-C8 is best as a coating material, (2) The pore diameter is about 7-10nm, (3) Pre-pressure of water is 6-8 Mpa and max-pressure is 60Mpa, (4) Water is usually good and antifreeze is available in cold circumference, (5) Single cylinder with pre-pressure is simple and high efficiency, (6) When the damper is applied to a car suspension, characteristics of hysteresis is different from a oil damper because the colloidal damper has stiffness and damping property and (7) In the analysis using molecular dynamics, movement of water and contact angle in the pore are measured for a single pore and water cluster.
