Shape memory alloy friction combined vibration isolator
The invention discloses a shape memory alloy friction combined vibration isolator. The shape memory alloy friction combined vibration isolator comprises an inner barrel connected with an upper flange and an outer barrel connected with a lower flange, wherein the inner barrel and the outer barrel are coaxial; the inner barrel and the outer barrel are radially connected through multiple layers of austenite shape memory alloy stranded wires; a slidable inner barrel base is arranged below the inner barrel; the slidable inner barrel base is internally provided with an axial austenite shape memory alloy spring and multiple groups of radial austenite shape memory alloy springs; the radial austenite shape memory alloy springs are connected with the inner barrel through sliding friction pairs; the lower part of the slidable inner barrel base is connected with the outer barrel through a self-adaptive sliding friction pair; an inclined surface which is small in the upper part and large in the lower part is arranged in the front of a sliding block; the outer wall of the lower part of the inner barrel is provided with a chamfer which corresponds to the inclined surface. The shape memory alloy friction combined vibration isolator comprehensively utilizes the characteristics of large deformation self-resetting capability of austenite shape memory alloy and high energy consumption of friction elements, and is capable of achieving the purposes of multi-directional and vertical vibration control and self-resetting of a controlled structure in a horizontal surface.
