Non-Newtonian Fluid Suspension System
• Minimized the mechanical fluctuations in a vehicle by replacing the conventional fluid with non-Newtonian fluid(Oobleck) in the damper.
• Determined properties like load, compressive strength, and elongation using Universal Testing Machine (UTM) and compared them with the existing model.
• Load vs. elongation, time, and displacement were plotted for different concentrations to compare the results.
Experimentation
• Two different Oobleck Mixtures are prepared with water and corn starch.
• Viscosity for these two mixtures is determined using Ostwald's viscous meter.
• Conventional suspension fluid is replaced with these two different mixtures in the damper assembly.
• The following test setup is loaded onto the Universal Testing Machine (UTM) to perform different tests.
• The compressive strength of the conventional fluid lies between 0.73 to 0.80 N/mm2, whereas Oobleck mixtures lie between .85 and 0.88 N/mm2.
• The peak load the damper could withstand before yielding was 520 to 560 N for conventional fluid but 600 to 620 N for Oobleck Mixtures.
