With the running orbit of the sun in space.
First, the various tracks of simulation planet operation
1st, heliocentric center of circle track is said：The sun does not travel forward in situ, starting switch I9a, controlled motor
Work, makes tellurion rotation in tellurion mounting seat 6, while driving the synchronous satellite ball 20 in fixes sleeve 17 around not transporting forward
Dynamic sun revolution, the revolution of the earth just can form circumsolar closed circle track；
2nd, heliocentric elliptical orbit is said：Starting switch moves forward the sun, restarts switch II9b, control
Motor II work processed, makes tellurion in tellurion mounting seat 6 be moved along circuit orbit 3, before tellurion moves to the sun just
Fang Shi, restarting switch makes the sun halt, and allows sun wraparound to travel back to set out on origin, the revolution of the earth can just be formed around
The occluded ellipse shape track of the sun；
3rd, heliocentric Wave spiral shape track is said：Starting switch make the sun go ahead movement stand fast, open
Dynamic switch I9a and switch II9b, controlled motor and motor II work, make tellurion rotation in tellurion mounting seat 6, drive simultaneously
Synchronous satellite ball 20 in fixes sleeve 17 is rotated, while tellurion in tellurion mounting seat 6 is moved along circuit orbit 3,
If fixing a pencil on 6, tellurion, which revolves around the sun, can just draw the Wave spiral shape track never closed on the ground.
2nd, revolution of the analog satellite on planetary orbit
Theoretical foundation：Primary wants rotation, and satellite could revolve round the sun around primary.The gravitation produced in primary rotation linear velocity drives
Under, satellite could revolve round the sun around the primary equatorial plane.
1st, revolution situation of the demonstration satellite below geo-stationary orbit：
Starting switch I9a, controlled motor tick-over makes the rotation of tellurion 4 in tellurion mounting seat 6, is rubbed while driving
The following satellite ball 12 of synchronization wiped on sleeve 15 revolves round the sun along tellurion 4, and now fine rule drives synchronous following satellite ball 12 and ground
The distance between globe 4 is less than the distance between synchronous satellite ball 20 and tellurion 4, and now synchronous following satellite ball 12 is along the earth
Run below surrounding geo-stationary orbit, satellite revolution speed is more than tellurion spin velocity.Because gravitation is more than repulsion, synchronous rail
Satellite revolution below road will all fall ground.
2nd, revolution situation of the analog satellite in geo-stationary orbit：
Starting switch I9a, controlled motor middling speed work, makes the rotation of tellurion 4 in tellurion mounting seat 6, while driving 21
On synchronous satellite ball 20 revolved round the sun along tellurion 4.Represent that the satellite is run along along geostationary orbit, satellite revolution speed is equal to
Tellurion autorotation angular speed.Satellite on geo-stationary orbit seems static motionless in the air.It is synchronous because gravitation is equal to repulsion
Satellite on track will not fall.
3rd, satellite revolution situation more than simulation geo-stationary orbit：
Starting switch I9a, controlled motor rapid operation makes in tellurion mounting seat 6 rotation of tellurion 4 while driving fixation
Synchronous above satellite ball 11 on sleeve 17 revolves round the sun along tellurion 4, being more than between synchronous above satellite ball 11 and tellurion 4
The distance between synchronous satellite ball 20 and tellurion 4, now satellite ball revolution speed, is slower than rotational-angular velocity of the earth.Work as satellite
Track is higher, and revolution speed is slower, after track reach a certain height, and satellite cannot be around the revolution of the earth to border.Together
The satellite more than track and within border is walked because gravitation averagely weighs with repulsion, so satellite will not fall.Beyond boundary line, by
It is less than repulsion in gravitation between the two, satellite will not be by terrestrial gravitation control.
4th, satellite synchronization rotation situation can directly be observed：
Satellite ball 13 is made into upper mark, satellite ball turns around around tellurion public affairs counterclockwise, itself can be around the thin of connection both sides
Line also rolls one and enclosed clockwise, is the synchronous rotation of satellite.
3rd, the reason for simulation earth revolves around the sun sometimes fast and sometimes slow：
Theoretical foundation：The earth revolves round the sun around the sun for the motion that goes ahead, and will form the Wave spiral shape rail never closed
Mark.See Fig. 4：
Based on Wave spiral shape track, illustrate why to occur when the earth revolves around the sun and neglect slow show soon suddenly
As：
Counted using earth a immediately below the sun on January 1 as starting point, the earth under around 90 degree to the sun dead astern x when, the sun,
The earth, the direction of motion is run in the opposite direction, and the gravitation of both sides has decelerating effect to the earth；By first point of Aries b, further around 90 degree to July 1
When directly over day aphelion C sun, the direction of motion of both sides is identical, is the sun preceding, draws the earth to advance, both sides' gravitation is over the ground
Ball has acceleration；The earth crosses aphelion C, is that terrestrial gravitation is drawn too during further around 90 degree to sun front X by autumnal equinoctial point d
Sun advances, and because sun Great Attractor is rear, has decelerating effect to the earth；The earth goes to a's in 1 day January next year immediately ahead of the sun
During 90 degree of underface, both sides go in the same direction, and because both sides' gravitation attracts each other, have acceleration to the earth, so that the earth is transported
Dynamic rail mark one waveform of formation, the earth of next year repeats 1 year story, forms another bar wave again；Two waves
Be connected, and form the Wave spiral shape track never closed, due to the earth on Wave spiral shape track around the sun
The equatorial plane revolves round the sun, because both sides' graviational interaction and the direction of motion, angle, front and back position different changes, just make the earth in revolution
Show to neglect slow phenomenon soon suddenly.
Simulated experiment：
1) preparation, while in starting switch I9a and switch II9b, controlled motor and motor II work, controlled motor
Speed work, makes the rotation of tellurion 4 in tellurion mounting seat 6, while driving the synchronous satellite ball 20 in fixes sleeve 17 to rotate, together
When tellurion in tellurion mounting seat 6 is moved along on circuit orbit 3, now drive fixes sleeve 17 on synchronous satellite ball
20 revolve round the sun along tellurion 4, now fine rule drive the distance between synchronous satellite ball 20 and tellurion 4 be more than geo-stationary orbit away from
From making the satellite be operated above around geostationary orbit；Earth rotation instrument rotational velocity is more than the revolution speed of satellite ball 20, by
It is equal to centrifugal force in gravitation between the two, geo-stationary orbit above satellite will not fall.Such as：Earth rotation 28 is enclosed, the moon around
The revolution of the earth one is enclosed, while synchronous rotation one is enclosed, such case is exactly situation more than geo-stationary orbit.
2) experiment starts：Support 1 is pulled by external force and wheel rectilinear movement is walked, by 0.05m/s low speed, 0.5m/s
When speed and 2m/s are carried out at high speed experiment, when translational velocity is 0.5m/s and 2m/s, in the revolution of tellurion mounting seat 6 to too
During the front of positive instrument, sun wraparound travels back to starting point, and the revolution of the earth is with regard to that can form occluded ellipse shape.Utilize Mercury ellipse
Track, subtracts the difference of perihelion with aphelion, except six months can calculate sun speed it is about per second 5 kilometers within.According to the sun
Translational speed and revolution of the earth speed, it is possible to use the spiral ringlet in Wave spiral shape track, measuring and calculating sun speed are per second
Less than 5 kilometers.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
Cross above preferred embodiment the present invention is described in detail, it is to be understood by those skilled in the art that can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
