Whole carbon fiber composite material support between devices

Abstract

The invention discloses a whole carbon fiber composite material support between devices. All upper joints are fixedly connected with all lower joints through a cross rod system to form a prism-shapedsupporting structure; every joint is capable of being fixedly connected with two adjacent supporting units through a standing rod and two slanting rods to form a stable tetrahedral structure, and thedemands of every upper joint bearing load in each direction are met; a reasonable configuration is conducted to every joint, a truss rod system is obtained by rod pieces axis crossing through one point, and the probability of the occurrence of local additional bending moment load and the like is reduced; hollow pipes are installed on the joints, the hollow pipes are sleeved with, hinged to and fixedly connected with the rod pieces, so that connection strength is further improved to bear larger load. Because carbon fiber joints and the rod pieces are adopted as a main body of the support, and the hinge is adopted, structure weight is reduced, and thermal stress between components is reduced; the reasonable structure rod pieces configuration is adopted, and reliability of the hinge is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical structures, and in particular relates to an all-carbon fiber composite material inter-device bracket. Background technique [0002] In most current spacecraft bracket structures, in order to reduce weight, the structural materials use carbon fiber with high efficiency as much as possible, and the bracket rods are easy to realize carbon fiber molding, but the limitation of the complex curved surface configuration of the joints leads to few examples of joints that are suitable for carbon fiber materials , the design and process molding technology of carbon fiber joints with complex configurations has become an urgent need. [0003] The research and development of carbon fiber weaving and other processes have led to more and more applications of carbon fiber weaving joints in spacecraft structures. Carbon fiber braided materials have higher interlayer mechanical properties, better impact resistan...
