| dc.description.abstract | The traditional damper devices used to dissipate the energy of seismic are lack of flexibility because of their inherent properties as specific structure and loading condition in design. After passive damper, semi-passive devices such as electro or magneto rheological damper gradually becomes a good alternativeness. Many researchers, however, have considered seriously to the durable and stable factors of supplying power for these semi-passive devices. At that time, a Shear Thickening Fluid (STF) has been found that its characteristics automatically change along with the difference of loading condition without
using external power. Therefore, many studies have had primary results in researching the STF filled damper by modifying the properties of fluid and using a simple piston. The STF damper might be used to alter the existing damper devices. However, those results only provided few specimens of STF fluid that are not enough to develop a damper with various properties. Hence, this study would conduct rheological tests to create a database of shear thickening fluid which was made from a pair of combination between three types of Nano-silica solutions (R812, R972, R974) with three softs of solvents (Polypropylene glycol, PPG) under various temperatures. From the database of STF, a database of properties of STF damper which obtains the dependent relationship between three parameters (damping coefficient, damping exponent, and concentration of STF), was also produced by regressing the numerical analysis results of STF filled damper. Furthermore, one prototype STF filled damper was tested to perform its characteristics and to compare with the results from numerical analysis in order to show error. Finally, some possible factors could cause the error such as geometry, temperature, material, and even theory; however, this study only conduct a comparison in term of gap error. | en |
