Embodiment Construction

[0013] The structure of the large-load open-section tie rod is shown in the attached figure. There are connecting holes for fixing at both ends of the tie rod. Its left side 1, right side 2 and web form a groove structure. In the groove formed by the left side 1, the right side 2, and the web 3, according to the specific length and bearing requirements of the tie rod, a certain number of ribs 4 are designed along the axis of the tie rod, and the ribs are perpendicular to the left side 1 and the right side. Side 2, one of the key points of this application is that in the groove on the side of the tie rod where water accumulation is likely to occur, the angle between the reinforcement rib 4 and the web 3 is required to be non-perpendicular, and each reinforcement rib is mutually parallel. When the above-mentioned pull rod is installed and used, one end of the pull rod is fixed on the higher fixed point 8, and the other end of the pull rod is fixed on the lower fixed point 9. N...

Abstract

A large-load open-section tie rod structure of an aircraft and its use method. The tie rod includes a left side, a right side and a web to form an I-shaped structure in section, and a There are multiple reinforcing ribs, which are characterized in that the reinforcing ribs are perpendicular to the left side and the right side, the relationship between the reinforcing ribs and the web is non-perpendicular, and the reinforcing ribs are parallel to each other.

Description

technical field [0001] The invention belongs to the aircraft structure design technology, and further relates to the waterproof design of the large-load tie rod of the aircraft, in particular to a large-load open-section tie rod structure of the aircraft. Background technique [0002] The tie rod is a typical structure in the aircraft body, which has the advantages of direct force transmission, simple structure, and high structural efficiency. There are various cross-section types of tie rods, and the common cross-section forms are "I-shaped" and "circular" cross-sections, each with its own characteristics. The I-shaped tie rod is more commonly used because of its open section, simple molding, low processing cost, and easy to realize the integrated design of the tie rod and the joints at both ends. The longitudinal elements of the I-shaped tie rods are all thin-walled structures. In order to increase the local critical instability stress, it is necessary to arrange multiple...
