Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing:

[0024] Please also see figure 1 and figure 2 , the present invention's grouped horizontal loading follow-up tare device comprises a sliding trolley 1, a trolley track 3 and a buckle connector (the connector generally adopts a steel cable); , bushings 7 and 9, and rolling bearings 7 arranged at both ends of the pull plate; the trolley track 3 is spliced ​​by a number of sub-tracks 12, and each sub-track is preset with the follow-up deformation and motion track of the sliding trolley, and is composed of The fixed plate 4 is connected and can be assembled or disassembled according to the usage conditions.

[0025] In this embodiment, the grouped horizontal loading follow-up buckle device of the present invention is mainly realized through the following technical solutions:

[0026] a) The sliding trolley composed of rolling bearings and the trolley track composed of channe...

Abstract

The invention belongs to a loading test follow-up weight deducting technology and relates to a bunching type horizontal loading follow-up weight deducting device used for an airplane structure strength test. The bunching type horizontal loading follow-up weight deducting device comprises sliding trolleys, trolley tracks and weight deducting connecting pieces. The sliding trolleys are arranged on the trolley tracks. One ends of the weight deducting connecting pieces are connected with a device which needs to be deducted weight and are connected on the sliding trolleys in an overlapped mode, and weight balancing blocks are arranged at the other ends of the weight deducting connecting pieces. According to the bunching type horizontal loading follow-up weight deducting device, the deducting of weights of a plurality of horizontal loading devices at the same time is achieved, deformation and follow-up following the test piece are achieved, weight deducting demands of one-piece or bunching devices are met, assembly according to demands can be achieved and a plurality of test demands are all considered. Due to the fact that the device is composed of channel steels and bearings, machining is fast, simple and convenient, installation technology is simple, practical applicability is strong, and cost is low.

Description

technical field [0001] The invention belongs to the technology of follow-up tare for loading test, and relates to a grouped horizontal load follow-up tare device used in the strength test of aircraft structure. Background technique [0002] In the static / fatigue strength test of a full-scale aircraft structure, the horizontal loading equipment is often large in size and heavy in weight due to the large load or the need to span the interference parts. In order to make the application of the horizontal load more realistic, it is necessary to The weight of the horizontally loaded equipment is deducted. At the same time, the large deformation of the test piece accompanied by the large load makes the horizontal loading equipment need to move with the deformation of the test piece, so as to avoid interference in the test process. [0003] During the test, there may be multiple pieces of horizontal loading equipment for one test piece, so while meeting the requirements for the fol...
