Description
Technical field
The invention belongs to aircraft structure strength test fields more particularly to a kind of for examining the connection of rudder face metal joint
Testpieces structure.
Background technique
Existing aircraft wing or rudder face are all made of the form of box section, and so-called box section form is upper and lower two layings or covering
With the metal segments of the box like of the rib composition between it, metal joint is set in the side of box section, multiple box sections pass through gold
Category connector, which is connected and fixed, is formed wing or rudder face.
And the testpieces form of single connector is examined when the connector of each key point or used at present or is used entire
The testpieces form of box section, but for rudder face structure, the composite structure connecting with connector needs weight when being also design
The structure that point considers, when test should the connection structure of butt joint also carry out evaluation, and single connector test part can not be examined
To the structure connecting with connector, box section testpieces is again excessively huge, and experimental scale and cost are larger, is not suitable for and tries with rudder face structure
It tests.
Summary of the invention
The object of the present invention is to provide one kind, solve current.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: it is a kind of for examining the connection of rudder face metal joint
Testpieces structure, including
Box section testpieces, the box section testpieces is by siding disposed in parallel and for fixing and supporting the more of the siding
A support rib constitutes box section structure, and metal joint is located in the middle part of box section testpieces；
