Slow-release damping mechanism based on shape memory polymer

The invention provides a slow-release damping mechanism based on a shape memory polymer and belongs to the technical field of space deployable mechanisms. N shape memory polymer slow-release damping components are hollow-out shape memory polymer sheet layers, each hollow-out shape memory polymer sheet layer is folded in half, the N folded shape memory polymer slow-release damping components are equally divided into two groups, and the two groups of folded shape memory polymer slow-release damping components are horizontally arranged side by side. At least one slow-release damping hinge deployable stiffening component is horizontally arranged between the two groups of folded shape memory polymer slow-release damping components, the two groups of folded shape memory polymer slow-release damping components are fixedly clamped to one end of the at least one slow-release damping hinge deployable stiffening component through one slow-release damping mechanism hinge clamping head, the two groups of folded shape memory polymer slow-release damping components are fixedly clamped to the other end of the at least one slow-release damping hinge deployable stiffening component through one slow-release damping mechanism hinge clamping head, and the upper outer surface and the lower outer surface of each group of folded shape memory polymer slow-release damping components are each provided with a heating layer. The slow-release damping mechanism is used in a deployable mechanism in the aerospace field.
