A high-energy-consuming modification buffer means

The present invention relates to a high energy consumption and large deformation buffering means belonging to the field of disaster prevention and mitigation. The high energy consumption is mainly composed of large deformation of the cushioning device comprising: a housing (1), a shape memory alloy ring (2), the chute (3), the pawl spindle (4), the sacrificial layer (5) and sliding rod (6 ), the entire apparatus was cylindrical rod; the number of inner housing has a corresponding number of sliding band gap blocking pawl spindle chute and spaced uniformly; partition outside, from outside to inside are sequentially placed a shape memory alloy collar, slip grooves, pawl spindle, the sacrificial layer and the active lever. The present invention provides apparatus having a high damping force, large deformation range, low hysteresis denaturation, etc., it can be applied in a wide range field of disaster prevention and mitigation.
