Number of patent application is that 201010165949.9 " combined air flotation device of unaffected by disturbance of air pipes " announced a kind of double-deck air-floating apparatus, this is a kind of device that can realize all kinds of frictionless motions by multiple-layer stacked, but because air-bearing shafts is slender rod piece, almost can't process apart from air-bearing shafts under the occasion long, therefore this short stroke air-floating apparatus that is designed to.Application number is that 201010166032.0 " two-dimensional plane air-floatation zero-gravity cradle " discloses long air-float guide rail of a kind of horizontal use, utilizes motor driving length guide rail to cooperate among a small circle air-float guide rail on vertically, thereby realizes that two dimension is without the friction translation.But because the laterally restriction of air-float guide rail difficulty of processing, the follow-up motion that can't carry out laterally large displacement is difficult to reach horizontal long Distance Transmission, has certain defective.
On the other hand, the sun wing is to be hinged by the polylith solar plate to form, and every solar plate has a sling point, in the process that sun wing simulation launches, need to provide to hang to every solar plate and support and track is followed.Carry out simultaneously two-dimentional inner plane motion with regard to a plurality of sling points of needs like this, and mutually do not interfere, therefore very large difficulty is arranged.

Two dimension without the long basic fundamental thinking that adopts apart from the multilayer air supporting erecting by overhang of motion of friction is:
The follow-up unit of plane motion air-floating apparatus can be done without frictional plane motion at the air supporting seat, namely laterally air-bearing shafts and vertically the air supporting cover can be transversely vertical frictionless motion, with after solar plate is connected, realize nothing passive the following of rubbing by erecting by overhang; Vertical air-bearing shafts fixing frame is fixed on the slide unit below of cross slide way, can moves with slide unit, guide track system moves according to the SC sigmal control guide rail slide block that feeds back, and realizes initiatively following.
Air-floating apparatus is by air supporting seat air feed, and air supporting seat inside is cavity, can connect air supporting cover suction port, and two air supporting seats are connected through flexible tracheae.The flexible tracheae of air inlet is fixed with transverse slider, can resupply the air supporting seat with the motion of slide block transversal stretching, because flexible tracheae light weight, stretchability is good, and servo-actuated distance is short, thereby the air supporting seat is when moving vertically, and the disturbing influence of tracheae generation is very little.Laser displacement sensor is fixed on the air-bearing shafts fixing frame by the installation of sensors plate, moves with slide block, and its wiring is installed and all can the motion of air-floating apparatus follow-up unit do not exerted an influence.
The air-floating apparatus follow-up unit only be about the extremely corresponding air supporting cover of two air supporting seats, horizontal air-bearing shafts, material is the light aluminum alloy material, thereby the inertia effects of follow-up unit when having reduced solar wing spreading.
The vertical and horizontal direction all is equipped with laser displacement sensor and Hall transducer, but the horizontal air-bearing shafts of laser displacement sensor Measurement accuracy, the vertically relative displacement of air supporting cover motion, with signal feed back to guide track system, follow the motion of air supporting follow-up unit by actuating motor control guide rail slide block, guarantee that the air-floating apparatus follow-up unit is in the effective travel of air-floating apparatus all the time, virtually prolonged passive scope of following.
Hall transducer plays the position limitation protection effect; displacement transducer or miscellaneous part produce fault in movement process; the horizontal vertically air-floating apparatus motion stroke that oversteps the extreme limit; will pull solar array and cause damage; thereby feed back signal to guide track system by Hall transducer; the effect of protection is played in the motion of restriction original direction.Because the sun wing mainly launches along the longitudinal, thereby Hall transducer only is installed on vertical air-floating apparatus.
Described guide rail is that Timing Belt drives linear module, and described slide unit can rolling friction type translation on guide rail, and the power that drives the slide unit translation provides by Timing Belt and synchronizing wheel.The Timing Belt two ends of longitudinal rail are fixedly mounted on a support with on the H shaped steel, described vertical motor is by belt wheel guide rail movement along the longitudinal, laterally actuating motor is fixed on the cross slide way, and transverse slider moves at cross slide way by Timing Belt and belt wheel thereof.Described guide rail is adjusted assembly and is installed between H shaped steel and the vertical linear module, is used for adjusting levelness, the parallelism of longitudinal rail.
Guide track system has two cover sensing systems, the straight-line displacement that one cover is measured the cross slide way slide unit, the straight-line displacement of another set of measurement longitudinal rail slide unit, in the solar wing spreading process, feed back the displacement signal of coming according to the plane motion air-floating apparatus, accurately the control slide block moves corresponding distance, when guaranteeing the guide motion all the time in the air-float guide rail scope, thereby realize long apart from the frictionless plane motion.
Because the individual layer hangar system is layered arrangement spatially, in the movement process of following the solar plate expansion, interference can not bump during the motion of erecting by overhang portraitlandscape.When sun wing rounding state, distance is the shortest between erecting by overhang, and namely each individual layer erecting by overhang need satisfy horizontal and vertical required distance, so that erecting by overhang is not interfered mutually.In the middle of the design of this device, cross rail crossbeam and horizontal linear module are no more than the twice of minimum range between two solar plate suspension centres, thereby do not produce interference between vertically when hanging solar plate, during the original state launched, the lateral displacement amount is very little, distance between plane motion air-floating apparatus longitudinal shaft fixing frame meets the demands, thereby under the solar plate impaction state and launch in the process of motion, can not produce between the erecting by overhang of each layer to influence each other.
When solar plate is in rounding state, distance between plates is very short, so distance is very short between sling point, but because the plane motion air-floating apparatus is frictionless motion, flexibility is very high, so, when erecting by overhang is not in vertical stable state, air-floating apparatus can produce simple harmonic motion, at this moment, if during to the guide rail servo-system, can causing initiatively, signal feed back follows, crossbeam can move, suspension rod collision with the upper strata erecting by overhang causes the accelerated motion of bed device follow-up unit, goes up like this guide track system of bed device and further follows, will cause and wholely can't stablize in system, more serious meeting produces thermal agitation because of the positive feedback between a system.Thereby before solar plate launched, we adopted servo-system to follow at a slow speed, and sensitivity is low, rocks middle guide at air-floating apparatus like this and follows at a slow speed, can not produce vibration, makes very soon erecting by overhang reach stable state.In solar plate exhibition process, adopt servo-system to follow fast, sensitivity is high, and speed, acceleration follows requirement in the time of satisfying solar plate and launch at a high speed.
Launching test stand is that whole large-scale air supporting supending roll type sun wing ground spreading testing apparatus provides support framework.Longitudinal rail is fixed on and launches on the test stand, and individual layer is hung dress by launching spatially paved in multi-layers of experiment frame.
When solar wing spreading, the motion of solar plate pulling plane motion air-floating apparatus, longitudinal rail and cross slide way are under servo followup system drives, the air supporting seat that drives the plane motion air-floating apparatus is followed the tracks of the solar plate motion, realize that large displacement length apart from follow-up motion, satisfies the routing motion between the multilayer erecting by overhang.
