Description
Technical field
The present invention relates to analogue experiment installation, be used for the undercarriage simulated experiment, particularly a kind of undercarriage is from warship simulated experiment mechanism.
Background technology
When military aircraft takes off at aircraft carrier, need to make aircraft reach needed lift-off speed with catapult-launching gear or the sliding big gun road that jumps.Undercarriage will bear all load gravity of aircraft in the sliding journey of jumping over, in addition, in cambered way, also will bear the centripetal acceleration normal pressure of aircraft.These two kinds of power make the compression of undercarriage impact damper.Aircraft leaves the moment of soaring in the mother ship carrier deck with V meter per second speed, and the moment projection of buffering piston bar produces impulsive force to piston and top cover.Whether impulsive force damages buffering piston, top cover or inner body, remains to be verified through simulated experiment.
Summary of the invention
The objective of the invention is for through simulated experiment undercarriage institute's load gravity in the sliding journey of jumping over; The checking impulsive force is carried out the situation of damage buffering piston, top cover or inner body; When thereby simulated aircraft flies away from mother ship carrier, the undercarriage moment projection process on the aircraft.
For realizing above purpose, the present invention takes following technical scheme, and a kind of undercarriage is from warship simulated experiment mechanism; It is characterized in that undercarriage is fixedly mounted on the anchor clamps through metal connecting piece, two ends of anchor clamps are equipped with fixed block; And be fixedly connected with guidepost, the centre is provided with balancing weight, under the undercarriage wheel dummy deck is housed; Dummy deck places on the rolling guide, and an end of rolling guide is installed with limited block, and pendulum is hung on the runner through the suspention cable wire; Runner all is fixedly installed in back timber with the lifting runner, and electronic latch hook articulates through cable wire and pendulum, and electronic latch hook is fixed in and promotes on the runner.
Undercarriage is under aircraft equivalent load W compressing, and undercarriage impact damper and undercarriage wheel vertical direction are compressed, and the wheel compression is also tightly touched the mother ship carrier dummy deck.Be equipped with the rolling bearing guide rail under the mother ship carrier dummy deck.The bump pendulum of the approrpiate wts of 4 parallelogram steel cables constraint of aerial suspension, the constraint of parallelogram steel cable guarantees pendulum at vertical in-plane moving, pendulum motion and be in horizontal attitude when clashing into false mother ship carrier deck all the time.The mother ship carrier dummy deck has rolling friction (friction factor 0.06) to amount to into 0.35 ° of angle of friction (wheel contacts deck plane and horizontal plane angle) with rolling guide.Its purpose is eliminated flying out of rolling guide friction force retardance pendulum bump mother ship carrier dummy deck, improves the relative velocity of undercarriage wheel and mother ship carrier dummy deck.
The invention has the advantages that, can imitate undercarriage more really, reach simulated aircraft makes undercarriage moment projection and impact damper inner impact from warship purpose in aircraft equivalent load compressing lower bumper and undercarriage wheel moment projection process.
