Description
Technical field
The invention belongs to a kind of experimental rig and test method, is more particularly to applied to obtain when ship-board aircraft warship and blocks
Hook hits the technical field of the dynamic response on deck.
Technical background
Arrester hook is a significant difference of the ship-board aircraft than land airplane, and its main function is smoothly marched into the arena in aircraft
After hook aircraft carrier check cable, power will be blocked and be delivered on fuselage, force aircraft.Generally, arrester hook when ship-board aircraft warship
Collided at first with deck, and the spring of limited height occurs under the effect of arrester hook longitudinal damper, meanwhile, involve fortune in aircraft
Under dynamic, gib head with it is slightly higher go out deck surface vacantly horizontal check cable engages.
Bounce-back height behind arrester hook initial collision deck is that arrester hook success tangles check cable and then the warship that succeeds
One of key, and the damping force that the deck counter-force that this is highly subject to arrester hook provides with arrester hook longitudinal damper whether
Matching relationship is close.One concentrated reflection of deck counter-force and damping force is the load suffered by arrester hook.
The history of the external research in terms of arrester hook load existing decades is very ripe.If the U.S. is in ship-board aircraft
In carrier-borne suitability flight test, substantial amounts of arrester hook load actual measurement is carried out, has formd specification；And the ship-board aircraft in China is just
At an early stage of development, also no carry out condition does not carry out measured test on substantial amounts of warship, and there is also dangerous high, difficult for continental rise flight test
The problems such as degree is big, somewhat expensive.
In order to solve the problems, such as that the load on arrester hook collision deck during warship is difficult to obtain, devise a set of simulation and block
The experimental rig that hook hits deck is hindered, arrester hook freely falling body is to obtain corresponding subsidence velocity, and rotation carrys out mould to collision disk at a high speed
Intend the course speed of aircraft, while the setting angle that can change collision disk moves to simulate aircraft carrier.Can thus not have
The dynamic response that arrester hook hits deck is obtained in the case of experiment and land-based test on warship, carries out simulating impact in the lab
Experiment, solve the problems, such as that danger is high, difficulty is big, somewhat expensive.
China has carried out a small amount of continental rise flight test to obtain the dynamic response that arrester hook hits deck, but this in recent years
Both for a certain specific model and its corresponding arrester hook, data are extremely limited, and can not simulate aircraft carrier motion for a little experiments.
The experimental rig realizes the state simulated to greatest extent when ship-board aircraft warship, meets that different ship-board aircrafts and difference are blocked
The test requirements document of hook, do not occurred similar experimental rig also in published document.
The content of the invention
The purpose of the present invention：For ship-board aircraft, in the case that experiment and land-based test difficulty are big on warship, simulation is devised

Freely glided along upright slide rail with lower, arrester hook gib head is contacted with collision disk to simulate arrester hook and first when ship-board aircraft warship
The collision process of plate.Wherein hanging basket can be with upward vertical movement in the presence of lifting motor；Freely glided by adjusting hanging basket
Preceding release altitude so that the falling speed of hanging basket reaches the subsidence velocity of ship-board aircraft in collision moment；Adjust arrester hook with
The position of disk is collided, arrester hook gib head is reached predetermined value, and gib head with colliding distance of the contact point of disk away from collision disk axis
Collision disk is first hit, and then hanging basket cushion at collision again, situation when this warship with ship-board aircraft is consistent；Pass through motor
Collision disk is driven to rotate at a high speed, the rotating speed of setting collision disk so that arrester hook gib head and the linear velocity at the point of impingement of collision disk
Reach course speed when ship-board aircraft warship；Arrester hook can be rebounded with collision disk collision rift, and same water is installed on arrester hook
Damper on flat turn axle can suppress its bounce-back；Buffer is used for the cushioning effect for simulating undercarriage when ship-board aircraft warship, adjusts
The parameter of whole buffer make it that the buffering effect of main landing gear when its buffering effect warship with ship-board aircraft is consistent.
Beneficial effects of the present invention：
(a) realize and simulate the experiment that arrester hook hits deck in the lab, solve during ship-board aircraft warship and block
The problem of dynamic response that resistance hook hits deck is difficult to obtain；
