The invention discloses a
shape memory alloy friction composite vibration
isolator which comprises an inner
barrel and an outer
barrel, wherein the inner
barrel is connected with an upper
flange, the outer barrel is connected with a lower
flange, the inner barrel and the outer barrel are coaxial, and the inner barrel is connected with the outer barrel through multiple
layers of
austenite shape memory alloy standard wires in the axial direction. A slidable inner barrel base is arranged under the inner barrel, an axial
austenite shape memory alloy spring and a plurality of sets of radial
austenite shape memory
alloy springs are arranged inside the slidable inner barrel base, the radial austenite shape memory
alloy springs are connected with the inner barrel through a sliding friction pair, and the lower portion of the slidable inner barrel base is connected with the outer barrel through a self-adapted sliding friction pair. A slope with a small upper portion and a large lower portion is arranged on the front portion of a sliding block, and a chamfer corresponding to the slope is arranged on the outer wall of the lower portion of the inner barrel. According to the shape memory
alloy friction composite vibration
isolator, the austenite shape memory alloy is characterized in that deformation self-reset capacity is strong and the
energy consumption of friction elements is high, the characteristics of the austenite shape memory alloy are made full use, and the purposes of multidirectional and
vertical vibration control in the horizontal plane and self-reset are achieved.
