Spiral bionic anti-shock structure and preparation method thereof

Abstract

The invention relates to the field of an anti-shock structure and manufacture thereof, in particular to a spiral bionic anti-shock structure and a preparation method thereof. An additive manufacturingtechnology of a thin-wall component which is widely applied to manufacture and provided with exquisite characters and complex structures is adopted, a shape memory alloy or a shape memory resin serves as a raw material, and the spiral bionic anti-shock structure is designed in a manner of combining hole pipe segments and tiny hole small pipe segments in the axial direction. On a cross section layer of each hole pipe segment, direction of an isometric spiral pattern that hole pipes surround a central hole channel is shown. On each cross section layer of each tiny hole small pipe segments, direction of multiple isometric spiral patterns that a hexagonal unit formed by seven tiny hole small pipes surround multiple the central hole channel is shown. Through a manufacturing strategy of linearscanning, layer-by-layer manufacturing and equal-angle rotation of each layer, a component with the spiral bionic anti-shock structure is prepared, wherein crystal growth direction of each cross section layer is in a layer-by-layer isometric angle rotation shape.

Description

technical field [0001] The invention relates to the field of impact-resistant structures and their manufacture, in particular to a spiral bionic impact-resistant structure and a preparation method thereof, which are suitable for impact-resistant components in military, aerospace and other fields. Background technique [0002] Soft landing technology is an important technology for planetary exploration. The outrigger of the soft landing gear detector for soft landing is one of the important components. If the outriggers of the detector cannot be successfully deployed, it will bring catastrophic consequences and lead to huge losses of national property. In order to meet the functional requirements of the soft landing gear system and make the buffer work stable and reliable, according to the characteristics of different soft landing gear systems, A four-leg suspension landing buffer with energy-absorbing properties is the best model, in order to effectively resist dynamic impa...
