The sports simulator includes one fixed support; one moving support below the fixed support and with one rider cabin on its lower plane; and one driven unit in between to rotate or shift the said moving support.
Description
The present invention relates to a kind of motion simulator, more specifically, relate to a kind of improved motion simulator, in this motion simulator, eliminated in the process of utilizing gravity generation kinaesthesis undesirable kinaesthesis has taken place, and therefore can produce the kinaesthesis more similar to virtual condition.
Usually, motion simulator is meant the motion of simulation such as objects such as aircraft or automobile so that people realize the device of kinaesthesis in the confined space.
As a kind of aforesaid general motion simulator, a 6DOF motion simulator 100 is presented among Fig. 1 to 3B, and wherein, a removable framework 120 is driven by six actuating devices 131,132,133,134,135 and 136.
As shown in Figure 1, existing 6DOF motion simulator 100 has such structure, and this structure comprises a fixed frame 110, a removable framework 120 and an a plurality of actuating device 131,132,133,134,135 and 136.
Described fixed frame 110 is fixedly mounted on the ground (gravitational field).Described removable framework 120 is arranged on the gravity direction top of fixed frame 110.A passenger compartment 140 is arranged on described removable framework 120 upper surfaces.
Described a plurality of actuating device 131,132,133,134,135 and 136 is arranged between fixed frame 110 and the removable framework 120.Electronic, hydraulic pressure or pneumatic actuator are usually as described each actuating device.
Described each actuating device 131,132,133,134,135 and 136 passes through corresponding a pair of universal joint 131a and 131b, 132a and 132b, and 133a and 133b, 134a and 134b, 135a and 135b and 136a and 136b are connected rotationally in its end.
Existing 6DOF motion simulator 100 with said structure is by driving a plurality of actuating devices 131,132,133,134,135 and 136 and thereby move removable framework 120 and make the passenger 170 in the passenger compartment 140 can realize and actual airplane or the similar sensation of automobile.
For example,, realize the sensation that is pulled rearward, and this sensation will continue when continuing to quicken after starting owing to quicken the passenger for a starting suddenly and the racing car that continues to quicken.
In order to produce this sensation, motion simulator 100 drives a plurality of actuating devices 131,132,133,134,135 and 136, and at first makes removable framework 120 to preacceleration, shown in Fig. 2 A.In these cases, the passenger 170 in the passenger compartment 140 is owing to inertia force is realized from the pulling at rear sensation.
But because the range of movement of motion simulator 100 has a limit, being accelerated also, proal removable framework 120 falls in this limit immediately.At this moment, shown in Fig. 2 B, when removable framework 120 anterior raised, passenger 170 is because gravity continues to realize described sensation.
On the other hand, as another example, for an automobile of turning along outer curve, because the centrifugal force passenger realizes the sensation that promotes to the bend lateral direction, and the passenger realizes this sensation constantly when proceeding to turn.
In order to produce this sensation, motion simulator 100 drives a plurality of actuating devices 131,132,133,134,135 and 136, and removable framework 120 is quickened to side direction, as shown in Figure 3A.In these cases, the passenger 170 in the passenger compartment 140 realizes the sensation that is pushed in the opposite direction owing to inertia force.
But, also be for this situation, because the range of movement of motion simulator 100 has a limit, be accelerated and fallen into immediately in this limit to the removable framework 120 of lateral movement.At this moment, shown in Fig. 3 B, when the direction of motion side of removable framework 120 was raised, passenger 170 continued to realize described sensation.
On the other hand, in Fig. 4-6, another example as existing motion simulator has shown a 3DOF motion simulator 101, its removable framework 120 by three actuating devices 131 ', 132 ' and 133 ' drive.
According to Fig. 4 to 6, the structure of existing 3DOF motion simulator is identical with the structure of 6DOF motion simulator, except the former have three actuating devices 131 ', 132 ' and 133 ' and being provided with an independent support component 150, undesirable inward/outward linear motion, left/right linear movement take place and are the rotational motion at center with top, bottom axis perpendicular to removable framework 120 surfaces in support component 150 restrictions.
Therefore, when describing the structure of 3DOF motion simulator 101, same numeral is used to represent the parts identical with the 6DOF motion simulator, and has omitted description of them.
Simultaneously, as mentioned above, since all motions of removable framework 120 can not only pass through actuating device 131 ', 132 ' and 133 ' limit, shown in the existing 3DOF motion simulator 101, be provided with an independent support component 150, be used to limit removable framework undesirable motion takes place.
Described support component 150 is installed in fluid cylinder 151 on the fixed frame 110, one by one and can constitutes along piston 152 and universal joint 153 that connects described piston and removable framework 120 that described fluid cylinder 151 moves up and down.
Under the situation of the existing 3DOF motion simulator of said structure,, that is,, when producing continuous accelerated motion or rotational motion as described above, only utilized gravity perpendicular to the free degree of gravity direction owing to there is not horizontal direction.
That is, in order to produce a kind of linear sensation of quickening, motion simulator 101 drive a plurality of actuating devices 131 ', 132 ' and 133 ' and rise the front portion of removable framework 120, thus make passenger 170 realize the sensation that pulls backward, as shown in Figure 5.
In addition, for the motion that rotates, motion simulator 101 drive a plurality of actuating devices 131 ', 132 ' and 133 ' and rise a side of removable framework 120, thus make passenger 170 realize the sensation that promotes to opposite side, as shown in Figure 6.
But, all have a kind of like this structure according to 100,101, two kinds of simulators of existing motion simulator of said structure, wherein, passenger 170 center of gravity is positioned at the center of rotation top of removable framework 120.
For above-mentioned reasons, when carry out from continuous linearity quicken or from centrifugal motion when side direction is quickened, that is, when utilizing gravity, there is the problem that undesirable acceleration occurs by perk in removable framework 120.
This inappropriate sensation (that is power) can be represented with following equation:
A
p＝A
v+A×R
pv+ω×ω×R
pv
Wherein, A
pBe the acceleration vector that the passenger realized of motion simulator, A
vBe the acceleration vector of the removable framework of motion simulator, A is that vector, R are quickened in the rotation of removable framework
PvBe the relative position vector of the passenger on maneuvering board, and ω is the velocity of rotation vector.
Thisly inappropriately feel it is A and R
PvThe cross product A of vector * R
PvCalculated value and ω, ω and R
PvThe cross product ω of vector * ω * R
PvThe summation of calculated value.
That is, in the structure of existing motion simulator 100,101, because passenger 170 center of gravity is positioned at the vertical direction of the center of rotation of removable framework 120, when applying a kind of acceleration sensation when beginning to rotate removable framework so that to the passenger, A * R
PvIt is opposite with the direction of the acceleration of wishing to produce that vector value becomes.
The curve that shows above-mentioned situation is shown among Fig. 7.Dotted line among Fig. 7 represents to control reference signal, and they repeat 3m/s
2Acceleration and deceleration, and solid line represents to take the acceleration that the passenger realized of driven motion simulator by importing above-mentioned signal.
In Fig. 7, opposite with the desired sensation of pushing a side to shown in the sharp-pointed part of protruding as the rightabout that changes along reference signal, the passenger realizes the unexpected gravitation to opposition side.
The result of this problem shown in the solid line among Fig. 7, has applied kinaesthesis (dotted line among a Fig. 7) rightabout kinaesthesis with desired generation, and, be delayed along orbiting motion time of desirable kinaesthesis.This means that the situation that the passenger experiences weakens.
Under the situation of formerly cited 6DOF motion simulator, because limited linear range of movement, if removable framework is rotated, the kinaesthesis opposite with desirable kinaesthesis will appear in the motion that rotates.
More than with 6DOF motion simulator and 3DOF motion simulator the problem of existing motion simulator has been described as two types example.But, although degree can change, but the problems referred to above of existing motion simulator occur in all motion simulators with different frees degree, and the function of these motion simulators is to utilize rotation and gravity to quicken to apply the linear sensation of quickening to the passenger, and its center of rotation is positioned at the passenger below.
Therefore, the technical assignment that the present invention will realize, promptly, the objective of the invention is and to solve the problems referred to above of existing motion simulator by a kind of motion simulator is provided, this motion simulator makes kinaesthesis feel similar to desirable, and reduces along the orbiting motion time by eliminating undesirable kinaesthesis when utilizing gravity to produce kinaesthesis.

According to motion simulator of the present invention, because removable framework is arranged on the fixed frame below, passenger's center of gravity is lower than the center of rotation of removable framework.
That is, even owing to A * R when rotating beginning
PvVector value is identical with the direction of the acceleration of desired generation, therefore, has following advantage, even undesirable kinaesthesis can not occur in the process of utilizing the gravity generation to quicken, and desirable kinaesthesis is along the time decreased of orbiting motion.
