Abstract

The invention discloses a 3D printing titanium alloy heat insulation pad which comprises a shell, through holes and a dot matrix filling cavity. The shell is six side surfaces of the hexahedral heat insulation pad and has a certain thickness; the through holes provide interfaces for bolt connection; the dot matrix filling cavity reduces the heat transfer capacity of the heat insulation pad and reduce the weight of the heat insulation pad. The inner cavity of the heat insulation pad is close to the through hole area with dense lattices, the through hole edge compression strength is enhanced, and other area lattices are sparse. The 3D printing titanium alloy heat insulation pad is suitable for rapid manufacturing of the titanium alloy 3D printing technology, and lightweight design and manufacturing of the heat insulation pad are achieved through the heat insulation performance of the titanium alloy and the weight reduction effect of the lattice structure.

Description

technical field [0001] The invention relates to the technical field of satellite structures, in particular to a 3D printed titanium alloy heat insulation pad. Background technique [0002] The satellite structure provides installation interfaces for various equipment. When some equipment needs to be installed in heat insulation, heat insulation pads are usually used. Titanium alloy heat insulation mat has high rigidity, strength and low thermal conductivity, and is usually used for heat insulation installation of important equipment. [0003] The star sensor bracket provides the installation interface for the star sensor and ensures the spatial pointing accuracy of the star sensor. During the satellite's in-orbit operation, the thermal deformation of the star sensor bracket caused by thermal load is the main reason for affecting the pointing accuracy of the star sensor. Therefore, good heat insulation measures should be taken for the star sensor bracket. The mounting feet ...
