A control method for the above-mentioned seat control system that circles in the air, described control method comprises the steps:
The flat peaceful control step of falling; Three electric cylinder synchronous; The parallel rising of tressel, and under the synchronous on-off effect of A font balancing stand, balancing stand length is fixed, the string of a musical instrument is constant, hooks linear shrinkage, and strand elongates, and forms the reach of tressel; Balancing stand is in the time doing open and close movement, because two pin of A font balancing stand adopt the radial bearing of usheing to seat, balancing stand is limited in and is only had in lateral rotation one degree of freedom, thereby limit balancing stand summit and filled the transverse movement of spherical joint bearing, in addition the length of balancing stand is fixed, the bearing fixed seat connecting can only move as sinusoidal trajectory along A font balancing stand, thereby drives the tressel connecting to play the flat also effect of crossed belt reach that rises; Otherwise; Three electric cylinder synchronous extension; Tressel pancake attached tape backspacing;
Swing control step; Three electric cylinders are divided into two groups, front cylinder and rear cylinder, two, front cylinder, rear cylinder one cylinder; Under the instruction control of center-control signal, three cylinders are done asynchronous flexible; Front group of cylinder synchronously rises exhibition, and rear group of cylinder is motionless or shrink; Balancing stand principle of work with flat peaceful fall identical; Cause the contained seat of tressel and occupant to lean forward; Otherwise; Front cylinder shrinks, and the motionless stretching, extension of rear cylinder, will cause layback effect; In practice, by cylinder position, front and back and be equipped with rational speed, control while leaning forward, whether need to be equipped with move ahead or after move; Lean forward and join while moving ahead, front cylinder shrinks, rear cylinder with than front cylinder faster speed shrink, and on before position is remained on; The effect that all causes the companion that leans forward to move ahead; Otherwise front cylinder stretches, as long as move effect after rear cylinder position, on front cylinder, just causing the companion that leans forward; Front cylinder is flexible except determining the front end lifting of tressel, is controlling moving forward and backward of tressel simultaneously;
Swaying style control step; Swaying style is actually mobile and does to rotate in a small amount along longitudinal axis, without translation motion; When left-leaning, left cylinder extends to low level, and right cylinder is contracted to a high position; Rear cylinder need be with the sleeping situation of pitching during depending on "Left"-deviationist, need lean forward in a high position, and need be faced upward at low level; High and low position is depending on pitching requirement, during without pitching at meta; Be in operation, left cylinder extends to low level, and corresponding left balancing stand folding angle large formation A word top spherical joint bearing is also in low level; Right cylinder does not stretch or extends to a high position, and corresponding right balancing stand folding angle less formation A word top spherical joint bearing is also in a corresponding high position, thus the formation tressel effect that longitudinally axle turns left; Because two balancing stands are except lateral separation is fixing, lateral rotation is independence and freedom degree, can form two different angles, causes longitudinal rotation of tressel; Two balancing stands " A " word top design is installed ball joint bearing, the angle forming with it because of rotation to meet tressel; Spherical joint bearing on two balancing stands, one is fixedly connected with bearing fixed seat, in order to the horizontal looseness of restraint frame; One connects with bearing fixed seat axial float, the sinusoidal deviation forming in order to revise longitudinal rotation of tressel;
" A " font balancing stand is designed in " A " word two pin and connected with fixed mount rear portion, and top connects with tressel is anterior; Due to the low right height in a left side, cause balancing stand folding angle inconsistent; Eminence reach, moves after lower; Form along vertical pivot, left-leaning left-hand rotation.
The main main points of the present invention are; 1, upgrade to Three Degree Of Freedom integrated motion by the self-movement of lever pendulum-type.2, seat is the force of rectangular arrangement formation and arranges.3, there is imbalance not controlled due to what force was not that equilateral triangle forms.
For solving Three Degree Of Freedom, the present invention adopts the moving source of suspension type three cylinders to make integrated motion.And three cylinders that break traditions are equilateral triangle layout type, do the first two rear arrangement.Significantly pull open front two cylinder distance, receive short front cylinder and rear cylinder distance.Being isoceles triangle arranges.
Because force is isosceles triangle, and at the bottom of triangle, grow up in Senior Two doubly more than.Impossible, also dangerous by the directed movement of cylinder self poisoning.In the design, decontrol the horizontal degree of freedom of cylinder body completely, two, cylinder all adopts universal coupling method, only controls lifting stretching location.And drawn between mobile at fixed body and quilt, arrange two " A " font balancing stands, with the transverse movement of restraint body, control longitudinal orbiting motion." A " word balancing stand two pin connect with fixed mount with rolling bearing units, on tip, connect with tressel with spherical joint bearing.Rolling bearing units are in order to do the horizontal rotation of " A " word balancing stand, and restriction transversal translation, controls longitudinal orbiting motion.Spherical joint bearing, in controlling tressel lengthwise movement, is separately made left and right single cylinder and is done longitudinal rotation control that intersection lifting produces.
Three forces are under the preset signals control of central control system, and in the time that cylinder is made synchronization lifting, the contained seat of mobile is done flatly up and down to rise translation operation, and the action that moves ahead in rising under the effect of " A " word balancing stand, on the contrary after move.In the time that front and back cylinder does to intersect lifting, the contained seat of mobile is done swing action.When left and right cylinder is done to intersect when lifting the action that swings of the contained seat of mobile.Three makes a concerted effort for three degree of freedom, claim suspension type Three Degree Of Freedom seat, and because of under the effect of balancing stand, three cylinders that break traditions are equilateral triangle layout type, tressel can significantly lengthen to reach the object that increases seat, therefore full name " swing arm equalizing suspension system formula Three Degree Of Freedom lengthens extraordinary seat ".The flat four-degree-of-freedom that claims before and after invention is accompanied with, meets the required simulation of movie theatre of circling in the air completely and sends out the requirement of circling in the air that flies to be the theme.As a complete new experience hardware of the movie theatre that circles in the air.The present invention pushes this type of movie theatre to a new mileage.
Beneficial effect of the present invention is: flight movie theatre multiple degrees of freedom circle in the air seat, its control system and control method that the present invention proposes, the unidirectional positioning free degree of former cause one byte in force is decontroled completely; Change by universal joint or globe joint, then make guide-localization by balancing stand; Break through a byte and locate the limitation that three forces must be uniform.
Extend the high simulation seat of another two quilts except moving degree of freedom by the be used as power Three Degree Of Freedom in source of three cylinders; Both reach the high-performance of 6 cylinder 6DOF emulation, enjoyed again the low price of 3 cylinder 3DOFs.
Two cylinder distance is arbitrarily extended by actual demand, using two balancing stands as a kind of mode that limits and control tressel operation degree of freedom and running orbit.The reversal of the natural order of things design of Three Degree Of Freedom in practice, produced topples over acting force by solving from gravity of hanging upside down by just putting, and makes supplemental support without more physical construction.

The method of operation and principle:
The present invention is mainly used in the huge ball curtain movie theatre that circles in the air, and product circles in the air as main taking simulation.Main body sense shows as lifting, and obduction, overlooks, "Left"-deviationist while turning greatly, Right deviation; And with composite type as the motion such as vert of about subduction zone, the Three Degree Of Freedom method of operation is not fully exerted herein.
Three cylinders of virgin state are in entirely stretching position, and position chair is in nadir, seat surface is liftoff approximately 50 centimeters, being also rearmost point provides the state of most convenient up and down for experiencer.Experience and start; Tressel is together with seat and the parallel rise of occupant above, and with moving ahead, like aircraft lift-off, experiencer's both feet also depart from ground simultaneously.Now movie theatre hatch door is opened, and under the effect of power, (outer power is unrelated to the invention, does not explain) advances to precalculated position by two side wheels 1 on fixed mount 2 by whole equipment outside, enters life's work state.
Make technical Analysis with three main decomposition motions below;
Flat peaceful falling: refer to Fig. 5, Fig. 6, three electric cylinder 3-1,3-2,3-3 synchronous.The parallel rising of tressel 16, and under the synchronous on-off effect of " A " word balancing stand 4-1,4-2, balancing stand length is fixed, the string of a musical instrument is constant, hooks linear shrinkage, and strand elongates.Form the reach of tressel 16.Balancing stand 4-1,4-2, in the time doing open and close movement, because " A " font two pin have adopted the radial bearing 13 of usheing to seat, are limited in balancing stand to only have in lateral rotation one degree of freedom.Thereby limited balancing stand summit and fill the transverse movement of spherical joint bearing 14, the length of balancing stand is fixed in addition.The bearing fixed seat 15 connecting can only be done sinusoidal trajectory motion along " A " word balancing stand.Thereby drive the tressel connecting to play the flat also effect of crossed belt reach that rises.Otherwise; Three cylinder synchronous extension; Tressel pancake attached tape backspacing.
Swing: refer to Fig. 7, Fig. 8, electric cylinder is divided into two groups, front cylinder and rear cylinder, front cylinder group comprises two electric cylinder 3-1,3-2; Rear cylinder group comprises an electric cylinder 3-3.Under the instruction control of center-control signal, three cylinders are done asynchronous flexible.Front group of cylinder synchronously rises exhibition, and rear group of cylinder is motionless or shrink.Balancing stand principle of work with flat peaceful fall identical.Cause the contained seat of tressel and occupant to lean forward.Otherwise; Front cylinder shrinks, and the motionless stretching, extension of rear cylinder, will cause layback effect.In practice, by cylinder position, front and back and be equipped with rational speed, control while leaning forward, whether need to be equipped with move ahead or after move.Join to lean forward and move ahead as example; Front cylinder shrinks, rear cylinder with than front cylinder faster speed shrink, and on before position is remained on.The effect that all causes the companion that leans forward to move ahead.Otherwise front cylinder stretches, as long as move effect after rear cylinder position, on front cylinder, just causing the companion that leans forward.In a word, front cylinder is flexible except determining the front end lifting of tressel, is controlling moving forward and backward of tressel simultaneously.Layback in like manner.
