Embodiment Construction
[0030] The content of the present invention will be further described below in conjunction with the accompanying drawings and specific examples.
[0031] The invention provides a large-stroke active adjustment damper for SMA wire split sleeve, such as figure 1 , figure 2 , image 3 As shown, the device comprises a split sleeve that is divided into two petals, i.e. a first split sleeve 2 and a second split sleeve 3, the inner wall 21 of the split sleeve is a cylindrical surface with a periodically variable diameter, and the piston outer wall 13 Complementary in shape, the first split sleeve 2 and the second split sleeve 3 are bonded by the split surface 29, and are tightly bound by the superelastic SMA wire 6 in a spiral shape through the outer wall surface 27, and the two ends of the wire The first external bolt 8 and the second external bolt 9 respectively connected to the two ends of the piston 1 are the interface between the damper and the outside, and the two sides of t...
