Composite vibration isolator for friction of shape memory alloy
The invention discloses a composite vibration isolator for the friction of a shape memory alloy. The composite vibration isolator comprises an inner barrel connected with an upper flange and an outer barrel connected with a lower flange, and the inner barrel and the outer barrel are coaxial to each other; a plurality of austenite shape memory alloy stranded wires are connected in a longitudinal direction between the inner barrel and the outer barrel, a sliding inner barrel base is arranged below the inner barrel, axial austenite shape memory alloy springs and a plurality of groups of radial austenite shape memory alloy springs are arranged in the sliding inner barrel base, the radial austenite shape memory alloy springs are connected with the inner barrel through sliding friction pair, and the lower part of the sliding inner barrel base is connected with the outer barrel through a self-adaption sliding friction pair; the front part of the sliding block is provided with a slope which is smaller in upper part and bigger in lower part, and the outer wall of the lower part of the inner barrel is provided with a chamber corresponding to the slope. According to the composite vibration isolator for the friction of the shape memory alloy provided by the invention, the characteristics of large-deformation self-resetting capacity of the austenite shape memory alloy and the high energy consumption of a friction element can be comprehensively used, and an aim of the vibration control and self-setting of a controlled structure in multiple directions and in a vertical direction can be realized.
