A Novel Approach for Shock Absorber----Colloidal Damper

Abstract

Abstract. Using the mixture of nanoporous materials and its associated lyophobic fluid for damping application is a novel technology called colloidal damper. Compression caused liquid intrusion transfers the mechanical energy into interface energy and so that producing damping effect and colloidal damper has great potential as shock absorber. In this paper, a colloidal damper consist water and hydrophobic silica gel particles as working medium is investigated. The working mechanism of colloidal is first introduced. Then, an experiment is conducted to investigate the mechanical properties of colloidal damper. Finally, the energy dissipation performance is analyzed.
