Shape memory alloy friction composite vibration isolator
The invention discloses a shape memory alloy friction composite vibration isolator which comprises an inner barrel and an outer barrel. The inner barrel connected with an upper flange and the outer barrel connected with a lower flange are coaxial and connected radially through multiple layers of austenite shape memory alloy strands, a slidable inner barrel base is arranged below the inner barrel, an axial austenite shape memory alloy spring and a plurality of groups of radial austenite shape memory alloy springs are arranged in the slidable inner barrel base, the radial austenite shape memory alloy springs are connected with the inner barrel through slidable friction pairs, and the lower portion of the slidable inner barrel base is connected with the outer barrel through a self-adaptive slidable friction pair. The front portion of each slider is provided with a big-end-down slope, and the outer wall of the lower portion of the inner barrel is provided with a chamfer corresponding to each slope. The shape memory alloy friction composite vibration isolator has the advantage that by comprehensive utilization of the austenite shape memory alloy with advantages of excellent large-deformation reset performance and high energy consumption of friction elements, multi-direction and vertical vibration control and automatic reset of controlled structures on a horizontal plane can be realized.
