Abstract

In view of a problem of poor durability of a barrel body and a metal connector of an existing composite connecting rod, the invention provides a connecting rod structure for combining a composite material with metal, and belongs to the technical field of aircraft weight reduction. The connecting rod structure provided by the invention comprises two metal connectors and a composite barrel body, wherein the two metal connectors are respectively connected with two ends of the composite barrel body; each metal connector comprises two metal lugs and one metal connecting structure; the two metal lugs are arranged at a first end of the metal connecting structure; the two metal lugs and the metal connecting structure form an integrated structure; the composite barrel body is an inner-outer double-cylinder structure; a tail end of the metal connecting structure of the two metal connectors is respectively connected with two end parts of an inner cylinder of the composite cylinder body; in an axial direction of the connecting rod, the metal connecting structure of the two metal connectors and the inner cylinder of the composite cylinder body are wound together by a composite material; and anouter cylinder of the composite cylinder body is formed on outer surfaces of the inner cylinder and the metal connecting structure.

Description

technical field [0001] The invention relates to a force transmission structure of an aircraft suspension box, in particular to a composite material connecting rod, which belongs to the technical field of aircraft weight reduction. Background technique [0002] The development of aircraft is mainly aimed at low cost and high carrying capacity. To achieve this goal, the first thing to solve is the problem of structural weight reduction. The lower link of the suspension box section is an important force transmission part of the suspension box section. It is used to connect Hang the bottom of the box section and the lower surface of the wing to transmit the thrust of the engine. Traditional aircraft, including B737, B777, and C919, all use metal materials, but with the advancement of composite material technology, compared with the traditional steel connecting rod structure, if the suspension connecting rod is made of metal and composite materials, the weight can be reduced 50%...
