Feasibility Study of Non-Newtonian Gelled Fluids as A Shock- And Vibration-Isolation Medium

Abstract

A research and development program was conducted for the purpose of developing methods of improving the operating characteristics of passive vibration and shock isolators. To achieve such improvement, rheological properties of base fluids in viscous dampers were altered for alternating flow conditions. Newtonian flow properties of both water and MIL-H-5606A hydraulic fluid were changed with chemical additives to yield pseudoplastic flow properties having an initial yield strength at low shear rates and 'shear thinning' characteristics at high shear rates. Both analytical and dynamic situations were checked. Laboratory experiments included tests with a special test damper and with a Government-furnished (GFE) damper. These devices were both tested as a part of isolation systems.
