The utility model patent " a kind of follow-up loading structure for airplane flap test " of Granted publication CN202083541U, loading actuator two ends sister block structure has been proposed, realize with two coasters on two displacement actuators control guide rails the location and the loading direction that load pressurized strut respectively, the structural design of this utility model patent, processed complex, and can only use at low level, be difficult to use for wing flap/slat folding and unfolding test of low level limited space.
Utility model summary of the invention
The purpose of this utility model is: provide the folding and unfolding of a kind of aircraft flap/slat to test high-order balance arm following loading mechanism, solve the problem of wing flap/slat low level limited space, solve the movement interference problem of the folding and unfolding of wing flap/slat and low level following loading mechanism.
The technical solution of the utility model is: high-order balance arm following loading mechanism is tested in the folding and unfolding of a kind of aircraft flap/slat, it comprises high-order balance arm, displacement pressurized strut, load pressurized strut, support post, wherein, displacement pressurized strut afterbody is hinged on support post, displacement pressurized strut head and high-order balance arm are hinged, high-order balance arm upper end and support post hinge, lower end and load pressurized strut afterbody are hinged, and load pressurized strut head is connected with wire rope, and wire rope is connected with aerofoil with rubberized tape by lever.
Support post is fixing by column diagonal brace 9 and firm banking 10.
When load(ing) point movement locus is in a vertical plane, high-order balance arm, displacement pressurized strut, load pressurized strut, balance arm and the support post of high-order balance arm following loading mechanism are in this vertical plane.
When load(ing) point movement locus is not in a vertical plane, make vertical of a track meta or basic meta, high-order balance arm, displacement pressurized strut, load pressurized strut, balance arm and the support post of high-order balance arm following loading mechanism are in this meta vertical plane.
Technique effect of the present utility model is: for the each load(ing) point of wing flap/slat, rotated to follow the folding and unfolding campaign of wing flap/slat by a displacement pressurized strut promotion balance arm, realize the dynamic load to load(ing) point by a load pressurized strut; Because moving component balance arm is in a high position, can avoids the folding and unfolding campaign of wing flap/slat and motion interference problem, and can avoid wing flap/slat and support stand causes low level limited space to cause the problem of test design difficulty.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In Fig. 1: the high-order balance arm of 1-; 2-displacement pressurized strut; The pressurized strut of 3-load; 4-balance arm rotary gemel; 5-load pressurized strut afterbody auricle connects hinge; 6-displacement pressurized strut head auricle connects hinge; 7-displacement pressurized strut afterbody auricle connects hinge; 8-support post; 9-column diagonal brace 10-column firm banking; 11-wing flap or slat; 12-rubberized tape; 13-connects lever, realizes load and distributes.
Embodiment
Below in conjunction with Fig. 1, concrete enforcement of the utility model scheme narrated.
The factors such as space, the support stand shared according to the folding and unfolding of wing flap/slat takes up room, wing flap/slat folding and unfolding angle, column riding position, designs the various building blocks of high-order balance arm following loading mechanism.
High position balance arm following loading mechanism is mainly by high-order balance arm 1; 2-displacement pressurized strut 2; 3-load pressurized strut 3; 4-balance arm rotary gemel 4; Load pressurized strut afterbody auricle connects hinge 5; Displacement pressurized strut head auricle connects hinge 6; Displacement pressurized strut afterbody auricle connects hinge 7; Support post 8; Column diagonal brace 9, column firm banking 10 form; Other is wing flap/slat 11, rubberized tape 12, lever 13.
Hinge is monaural and ears connected mode, and all monaurals adopt monaural ball corner structure.
High-order balance arm 1, displacement pressurized strut 2, load pressurized strut 3, balance arm and the support post 8 etc. of high-order balance arm following loading mechanism are arranged in its working face.Working face is to determine like this: if the movement locus of wing flap/slat load(ing) point (when zero load) is in a vertical plane, using this plane as working face; If load(ing) point movement locus is not in a vertical plane, make vertical of a track meta or basic meta, made working face.
High-order balance arm following loading mechanical work principle: measure wing flap/slat folding and unfolding angle beta by sensor, adopt MTS/MOOG multichannel synchro-loading control system to carry out closed-loop control to displacement pressurized strut and load pressurized strut, control rate is displacement pressurized strut stroke " angle-displacement " spectrum and load pressurized strut load " angle-load " spectrum, and independent variable is wing flap/slat folding and unfolding angle; When the folding and unfolding of wing flap/slat, displacement pressurized strut 2 promotes balance arm 1 and rotates around hinge 4, makes the load line of load pressurized strut 3 realize dynamic load perpendicular to load(ing) point.
In order not take near space wing flap/slat below and low level, be the top that balance arm is placed in wing flap/slat by the moving component of following loading mechanism, and be connected with support post with hinge, promoting balance arm with a displacement pressurized strut rotates, realize with the folding and unfolding of wing flap/slat with motion tracking, load with a load pressurized strut, specifically comprise:
