碩士 === 國立交通大學 === 土木工程系所 === 94 === The objective of this research is experiment analyzing a servocontrol fluid damper. This research is a continue study that is to investigate the physic nature and energy dissipation mechanism of a semi-active servocontrol fluid damper and the feasibility of applying it in a structural control system. The control system is designed via an electronic control valve and a mechanical switch. The experiment is achieved in Structural Lab in NCTU. During the experiment, the damper force and relative displacement are measured by load cell and LVDI via different frequencies. The opening areas of electronic valve is also changed in four different values ,5 , 10, 15 and 20 voltages. After that, the experimented data are applied to the Bingham model to analyze the corresponding parameters, damping and stiffness values. The corresponding damping and stiffness values of the damper are calculated with different frequencies via linear regression. The analyzing results indicate that the damping values of the servocontrol fluid damper can be control through changing the opening valve area. The stiffness value of the damper is linear proportional variant with variant frequencies.
