Abstract |
|
In this study, a smart damper based on shear thickening fluid (STF) was developed, and its dynamic mechanical performance was investigated. STFs with various mass fractions were prepared, and their rheological properties were characterized under steady-state and dynamic conditions. These fluids were incorporated into dampers, and dynamic tests were conducted under different frequencies and amplitudes to analyze the variation in damping force. Experimental results suggest that the STF-based damper exhibits effective damping performance. A force-velocity relationship model of the STF damper was established based on the experimental data, revealing that during the compression stage, the behavior conforms to Boltzmann’s law, while during the recovery stage, it exhibits exponential behavior. By integrating the relationships among STF mass fractions, loading speeds, and maximum output damping forces, a three-dimensional plot was generated to guide future research and industrial applications. |
