For test data.Aircraft fatigue test load usually has drawing, pressure both direction load.Especially in the test of fuselage fatigue load,
The test load of fuselage sideway stance and fuselage side are tangentially parallel, specially tangential upward and tangential downward both direction.It passes
System loading method be by be pasted onto testpieces surface rubberized tape apply draw load, fatigue load lateral for fuselage, specifically
Way is to distinguish sticking cloth band in testpieces upper and lower position, and then in upper and lower position, group lever system is loaded respectively.
Therefore, traditional loading method needs two sets of rubberized tapes, two sets of lever systems, two sets of loading systems and two sets of control systems, if
Standby investment is more, and installation workload is big, inefficiency.In addition, there is loading system in traditional loading method upper and lower position, to load
Very big influence is brought with inspection.
Utility model content
The purpose of this utility model is to solve problems of the prior art, provides a kind of compact-sized, test efficiency
Height, while the tangential biaxial loadings device of fatigue test for reducing equipment investment and installation workload.
To achieve the goals above, the utility model adopts the following technical solution: a kind of tangential biaxial loadings of fatigue test
Device, including rubberized tape and lever system, rubberized tape are pasted on fuselage two sides, are provided with connection in the upper and lower part of rubberized tape
Portion, interconnecting piece is interior inserted with rod-like element, and opening is provided on interconnecting piece, is provided in opening for connecting upper and lower rod-like element
Connector, rubberized tape is divided into fuselage two sides；Lever system includes primary lever and second lever, and primary lever is for connecting
The rod-like element of fuselage two sides rubberized tape lower part, second lever is for being connected and fixed adjacent primary lever.
Preferably, the rubberized tape be several and it is symmetrical.
Preferably, the rubberized tape two are one group, and the interconnecting piece of two rubberized tapes is coaxial.
Preferably, the rod-like element is aluminium bar, and interconnecting piece is short aluminium bar in insertion, and being inserted into lower interconnecting piece is long aluminium
Stick, long aluminium bar run through the interconnecting piece of adjacent rubberized tape.
Preferably, the primary lever is in U-shape, and end is connected with monaural connector, the rod-like element insertion of rubberized tape lower part
In monaural connector.
Preferably, connector is fishplate bar or cable wire.
Preferably, the rubberized tape is sewed by canvas.
When test applies tangential upward load, lever system transfers load to long aluminium bar, and long aluminium bar again passes load
It passs on directly connected rubberized tape, rubberized tape transfers load to testpieces again；Test applies tangential downward load
When, lever system transfers load to long aluminium bar, and long aluminium bar passes to short aluminium bar by fishplate bar, and short aluminium bar transfers load to again
Directly on connected rubberized tape, rubberized tape transfers load to testpieces again.
The utility model compared with prior art, has the advantages that
1, the load that can apply upward, downward both direction, reduces a set of loading system, reduces equipment investment, drop
Low installation workload.
2, compact-sized, test load response is fast, improves test efficiency.
3, loading system only is arranged in underbelly, back does not have loading equipemtn, and current check and arrangement is facilitated to survey
Measure equipment.

Specific embodiment
It should be noted that the noun of locality " upper and lower " etc. in the present embodiment is described according to shown in attached drawing, it is not
Limitations of the present invention.
1-3 is further described the utility model with reference to the accompanying drawing: a kind of tangential biaxial loadings device of fatigue test,
It is formed by tangentially loading rubberized tape 1, short aluminium bar 2, long aluminium bar 3, fishplate bar 4, monaural connector 5, primary lever 6 and second lever 7.
Tangential load rubberized tape 1 is sewed by canvas, and the useful gap in load in position among rubberized tape, four tangential
It loads rubberized tape 1 and forms a tangential biaxial loadings unit, i.e., two are one group.Short aluminium bar 2, long aluminium bar 3 are each passed through adhesive plaster
Top, lower part with 1, two short aluminium bar 2 respectively pass through the rubberized tape 1 of top in tangential biaxial loadings unit, and long aluminium bar 3 passes through
Two of lower section coaxial tangential load rubberized tape 1 and monaural connector 5, monaural connector 5 are located between two rubberized tapes 1；Fishplate bar 4
The aperture of connecting hole is consistent with short aluminium bar 2 and 3 diameter of long aluminium bar, and fishplate bar 4 passes through 1 gap of rubberized tape and covers in short aluminium bar 2 and long aluminium
On stick 3.Rubberized tape 1 is pasted onto testpieces surface, when test, load by fishplate bar 4, short aluminium bar 2, long aluminium bar 3 and rubberized tape 1 by
