HYDRAULIC DAMPER USING SHAPE MEMORY ALLOYS CAPABLE OF BEING STABLY PERFORMED REGARDLESS OF THE STRENGTH OF DAMPING FORCE

摘要

PURPOSE: A hydraulic damper using shape memory alloys is provided to generate damping force copping with vibration in wide frequency range by changing an orifice by shape memory alloys deformed by the applying of current.;CONSTITUTION: A hydraulic damper using shape memory alloys(160) comprises a cylinder(110), a piston(120), working fluid(130), an orifice(140), and a movable block(150). The cylinder comprises inner space. The piston comprises a piston rod(121) and a piston head(122). The cylinder is filled with the working fluid. The orifice is formed to pass the piston head vertically. The movable block is installed in the piston head to be moved.;COPYRIGHT KIPO 2013
