    초록 In this study. new shock absorbing system is proposed by using nano-technology based on the experimental analysis. The new shock absorbing system is complementary to the hydraulic damper, having a cylinder-piston-orifice construction. Particularly for new shock absorbing system, the hydraulic oil is replaced by a colloidal suspension, which is composed of a porous matrix and a lyophobic fluid. This paper presents an experimental investigation of a reversible colloidal damper. which is statically loaded. The porous matrix is consisted of silica gel, with labyrinth and central-cavity architecture, modified by long linear chain of n-alkylchlorosilanes, in order to built-up a hydrophobic surface. Water is considered as associated Iyophobic liquid. Test rig of damper is designed for the measuring technique of the dynamic hysteresis of damping characteristics. 8y extracting the structural influence. the variation of the damper's dissipated energy versus working pressure against shock excitation are obtained. The theoretical computations agree reasonably well with the experimental results. As a result, the proposed new shock absorbing system was proved to be an effective one. which can replace with the conventional one.
