Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] This device simulates the aerodynamic load of the vertical tail of the aircraft during flight, and designs a loading test device for the vertical tail loading vibration table to move synchronously with the vertical tail and apply dynamic load. Take a vertical tail as an example, specifically (see below Figure 1-Figure 4 ) There is a gantry 2 above the vertical tail 1, and a follower frame 3 is fixed on the gantry 2. The follower frame 3 forms a rectangular structure, and the vertical tail 1 is in the middle of the follower frame 3. The vertical side of the frame 3 is parallel to the vertical tail 1 and has a certain angle with the ground. The structure of the two sides divided by the vertical tail 1 of the follow-up outer frame 3 is symmetrical. A group of circular sliding bearings 4 are coaxial with each other and with the vertical tail rotation sha...

Abstract

The invention relates to an aircraft vertical tail dynamic load follow-up loading test device, which relates to an aircraft vertical tail loading test technology. The technical solution includes: there is a gantry above the vertical tail, and a follow-up outer frame is fixed on the gantry. The follow-up outer frame has a rectangular structure, the vertical tail is in the middle of the follow-up outer frame, and the vertical The direction is parallel to the vertical tail and has a certain angle with the ground. The structure of the two sides divided by the vertical tail is symmetrical. There is a set of circular sliding bearings on the upper and lower sides of the following outer frame, which are coaxial with each other and the rotation axis of the vertical tail. axis.

Description

technical field [0001] The device relates to an aircraft loading test technology, in particular to an aircraft vertical tail dynamic load follow-up loading test device. Background technique [0002] At present, the dynamic load test technology of the aircraft vertical tail and the simultaneous loading technology of static and dynamic loads are blank in China. This test device was also blank. The static loading test technology for the vertical tail of the aircraft is mature, but there is a big gap between the test load spectrum and the real load of the aircraft. A more realistic load spectrum should combine static and dynamic loads. Contents of the invention [0003] Purpose of the invention: To provide an aircraft vertical tail dynamic load follow-up loading test device, which can realize static and dynamic combined loading, and can dynamically load tracking aircraft vertical tail deformation loading. [0004] Technical solution: a dynamic load follow-up loading test dev...
