Problems solved by technology

However, in the design and manufacture process of micro-aircraft, the static strength test of the aircraft structure is not enough.
At present, there is no static strength test platform specially used for measuring micro-aircraft. In many cases, it is roughly designed with the engineering experience of designers, and quantitative analysis cannot be done, so that the design results cannot achieve high accuracy. Aircraft structures are usually overstretched and some local weight is redundant

Embodiment Construction

[0017] To test the static strength of the aircraft, the key is to be able to measure the strain and displacement of various parts of the structure, and then complete the strength test.

[0018] The invention mainly realizes the experiment of the static strength of the test piece by measuring the strain and displacement at different positions of the loaded test piece. The process is: fix the test piece on the load-bearing wall (1) or the load-bearing ceiling (3), use different loading methods to apply a certain load to the test piece, and then feedback the measurement results in real time through the displacement and strain measuring device On the computer, get the strength and stiffness data of the test piece.

[0019] The technical scheme of the specific implementation of the present invention will be described below in conjunction with the drawings.

[0020] Such as figure 1 As shown, the test bench according to an embodiment of the present invention includes a bearing wall (1), a...

Abstract

The invention relates to a static test system for a min-aircraft structure, which comprises a bearing ceiling (3) comprising multiple sliding rails supported by multiple struts (103), wherein the sliding rail (104) is used for suspending a testing device and / or a testing piece; a bearing terrace (2) comprising multiple vertical rails (101) and multiple horizontal rails (102), wherein the position of the horizontal rail on the vertical rail can be changed randomly. The static test system has the advantages that: 1) a static test platform for a mini-aircraft is provided; therefore, a simple and practical test platform is provided for the design and manufacture of the mini-aircraft; 2) a good experimental platform is provided for teaching experiments so as to help the students have a general knowledge of the structure intensity of the mini-aircraft; 3) a design structure testing tool is provided for design personnel to improve the structure design and analysis capability.

Description

Technical field [0001] The invention relates to the design of a static test system for the structure of a small aircraft, belonging to the field of structural design of the aircraft. Background technique [0002] The present invention is mainly applied to the static strength test of the wing, tail and other components of the miniature aircraft and the complete machine. Therefore, the description of the background technology is mainly focused on this type of test. [0003] During the design process of military and civil aircraft, multiple static strength tests are carried out on various parts of the aircraft and the whole aircraft to verify whether the strength and rigidity of the aircraft can meet the requirements, and the design is improved to varying degrees based on the experimental results. However, in the process of designing and manufacturing the miniature aircraft, the static strength test of the aircraft structure is not enough. At present, there is no static strength test...
