Description

Technical Field

[0001] The invention relates to the field of hardware equipment design of a ground zero-gravity air flotation simulator, in particular to a housing fixing bracket of a ground zero-gravity air flotation simulator. Background Art

[0002] The ground zero-gravity air flotation simulator is a complex electromechanical device used to simulate microgravity or zero-gravity environments. It is often used in spacecraft development, astronaut training, and scientific experiments. Its main principle is to use air cushion technology to support objects on a smooth plane through a thin layer of airflow. This airflow is ejected through multiple small holes to form a uniform air cushion, allowing objects to float above the air, thereby reducing friction and allowing objects to move freely on a two-dimensional plane, thereby simulating the weightlessness in space. The ground zero-gravity air flotation simulator usually includes the main mechanical structure subsystem, air flotation subsystem, air supply subsystem, electrical subsystem (including control execution subsystem, inertial navigation measurement subsystem, power supply subsystem), wireless communication subsystem, and simulator shell subsystem.

[0003] Usually, according to the experimental requirements, a protective shell needs to be installed on the exposed ground zero-gravity air flotation simulator base to prevent the ground zero-gravity air flotation simulator from violently colliding during operation and damaging the installed electromechanical equipment. At the same time, the protective shell can ensure the safety of the operator to a certain extent. Therefore, for the experiment of the ground zero-gravity air flotation simulator, a reliable protective shell fixing device is required to ensure the stable connection between the shell and the ground zero-gravity air flotation simulator base.

[0004] On the other hand, according to some special experimental requirements, such as using a ground-based zero-gravity air flotation simulator to simulate the spatial movement of equipment such as airplanes, ships and space shuttles, this requires that the base of the ground-based zero-gravity air flotation simulator needs to fix an experimental simulation shell of equipment such as airplanes, ships and space shuttles to obtain reliable fluid simulation data, etc. This requires the design of a fixing device that is adapted to the experimental simulation shell to ensure a close fit between the experimental simulation shell and the ground-based zero-gravity air flotation simulator.

[0005] Although the prior art provides various devices and methods for fixing the shell of a ground zero gravity air flotation simulator, these devices and methods often have some problems. For example, some devices may not provide sufficient stability, while other devices may be too complicated and not easy to install and use.

[0006] Therefore, there is an urgent need to provide a simple and effective ground zero-gravity air flotation simulator shell fixing bracket to solve the above problems. Summary of the invention

[0010] Preferably, a boss is provided in the middle of the side surface of the middle plate, and the boss is used for mounting in conjunction with the side plate.

[0011] Preferably, a stepped plane is provided below the middle plate, and a plurality of planar straight slots are provided on the stepped plane, and the planar straight slots are used to fix the outer shell fixing bracket to the base of the ground zero-gravity air flotation simulator.

[0012] Preferably, the size of the planar straight slot is determined according to the relative sizes of the mounting base and the outer shell of the ground zero-gravity air flotation simulator.

[0013] Preferably, the top plate is provided with a plurality of shell connection threaded holes or shell connection straight slots, the shell connection threaded holes or shell connection straight slots are used for simulating external connection of two adjacent parts of the space shuttle, and the shell connection threaded holes or shell connection straight slots are equipped with shell connection screws.

[0015] Preferably, the top plate is in a contoured shape designed accordingly to the outer shape of the outer shell, and the outer shell fixing bracket is relatively tightly connected to the outer shell of the ground zero-gravity air flotation simulator.

[0016] In summary, the shell fixing bracket of a ground zero-gravity air flotation simulator of the present invention includes components such as a top plate, a side plate, and a middle plate through a simple and reliable connection method, and is connected by screws to ensure that the components are tightly connected. The middle plate is designed with a boss, a stepped plane, and a fine-tuning plane straight slot, which provides a higher assembly accuracy for the connection between the shell and the base of the ground zero-gravity air flotation simulator. The design of the plane straight slot allows fine-tuning and adjustment between the shell and the mounting plate of the ground zero-gravity air flotation simulator to ensure that their relative position and positioning are accurate.

[0024] Unless otherwise defined, technical or scientific terms used in the present invention shall have the common meanings understood by one having ordinary skills in the field to which the present invention belongs.

[0025] The present invention takes the space shuttle ground motion simulation test experiment as an example, and designs a simple, reliable and easy-to-install fixing bracket based on a ground zero-gravity air flotation simulator to connect the space shuttle simulation shell and the ground zero-gravity air flotation simulator base.

[0026] The ground zero-gravity air-floating simulator 9 used in the space shuttle ground motion simulation test experiment can realize two-dimensional motion in the horizontal plane on the air-floating platform through the plane support air foot 91 and the air supply system 92.

[0027] In order to stably and quickly fix the outer shell of a simulation model of a space shuttle on a base of a ground zero-gravity air flotation simulator 9, a ground zero-gravity air flotation simulator outer shell fixing bracket 1 is provided, comprising a top plate 2, side plates 3 and a middle plate 4. A pair of side plates 3 are respectively arranged on both sides of the middle plate 4, and the top plate 2 is arranged above the middle plate 4.

[0028] like Figure 1 As shown, it can be seen that the overall structure of the housing fixing bracket 1 includes a top plate 2, a side plate 3, and a middle plate 4, and the fastening connection of each component is ensured by screw connection, wherein the side plates 3 symmetrical on both sides are connected to both sides of the top plate 2 and the middle plate 4 by screws.

[0029] Furthermore, the top plate 2 is provided with a plurality of top plate through holes 21 , and the top plate through holes 21 are provided with corresponding top fixing screws 22 , and the top plate 2 is fixedly connected to the middle plate 4 via the top fixing screws.

[0030] The side plate 3 is provided with a plurality of first side plate through holes 31 , and the first side plate through holes 31 are provided with first side plate connecting screws 33 . The side plate 3 is fixedly connected to the top plate 2 via the first side plate connecting screws 33 .

[0031] The side plate 3 is provided with a plurality of second side plate through holes 32 , and the second side plate through holes 32 are provided with second side plate connecting screws 34 . The side plate 3 is fixedly connected to the middle plate 4 via the second side plate connecting screws 34 .

[0032] Furthermore, a boss 5 is provided at the middle position of the side surface of the middle plate 4 , and the boss 5 is used for mounting in conjunction with the side plate 3 .

[0033] The middle plate 4 has a boss 5, which is cooperatively connected with the side plate 3, and has a stepped surface 6 at the bottom and a flat straight groove 61 for fine adjustment on the top to ensure accurate connection with the outer shell fixing bracket 1 and the base of the five-degree-of-freedom ground zero-gravity air flotation simulator 9.

[0034] Furthermore, a stepped plane 6 is provided below the middle plate 4 , and a plurality of planar straight slots 61 are provided on the stepped plane 6 . The planar straight slots 61 are used to fix the outer shell fixing bracket 1 to the base of the ground zero-gravity air flotation simulator 9 .

[0035] The design of the flat straight slot 61 on the outer shell fixing bracket 1 allows flexible fine-tuning of the relative position of the outer shell and the mounting plate of the ground zero-gravity air flotation simulator 9, thereby improving the assembly accuracy.

[0036] Furthermore, a plurality of shell connection threaded holes 7 or shell connection straight slots 8 are provided on the top plate 2, and the shell connection threaded holes 7 or shell connection straight slots 8 are used for simulating external connection of two adjacent parts of the space shuttle, and the shell connection threaded holes 7 or shell connection straight slots 8 are equipped with shell connection screws 71.

[0037] The shell connection threaded holes 7 or the shell connection straight slots 8 on the top plate 2 further enhance the connection reliability between the ground zero-gravity air flotation simulator shell fixing bracket 1 and the shell.

[0038] Furthermore, the housing fixing bracket 1 is provided with at least one pair of mounting plate edges symmetrically mounted on the ground zero-gravity air flotation simulator 9 .

[0039] Furthermore, the top plate 2 is in a contoured shape designed according to the outer shape of the shell, and the shell fixing bracket 1 and the simulator shell are relatively tightly connected.

[0040] Specifically, by adjusting the relative installation positions of the shell fixing bracket 1 and the front mounting platform and the rear mounting platform of the ground zero gravity air flotation simulator 9, the shell fixing bracket 1 and the space shuttle simulation shell are closely connected. The shape of the top plate 2 can be designed according to the shell, such as the outer shape of the space shuttle, for example, the shape of the top plate 2 can be designed to be an arc or the outer shape of the space shuttle, so that the shell fixing bracket 1 can be relatively closely connected to the outer shell of the space shuttle.

[0041] like Figure 2 As shown, the housing fixing bracket 1 is mounted on the circular mounting platform 93 of the ground zero-gravity air flotation simulator 9 through three planar straight slots 61 .

[0042] Among them, Figure 3 and Figure 4 As shown, a pair of fixing brackets are installed on the front part of the circular mounting platform 93 for simultaneously connecting the shuttle head 94 and the shuttle middle part 95, and a pair of shell fixing brackets 1 are installed on the rear part of the circular mounting platform 93 for connecting the shuttle middle part 95 and the shuttle tail part 96.

[0043] In summary, the housing fixing bracket of a ground zero-gravity air flotation simulator described in the present invention provides a higher assembly accuracy for the connection between the housing and the base of the ground zero-gravity air flotation simulator. The design of the planar straight slot allows for fine-tuning and adjustment between the housing and the mounting plate of the ground zero-gravity air flotation simulator to ensure that their relative positions and positioning are accurate. The housing connection threaded holes or housing connection straight slots on the top plate improve the connection reliability between the housing fixing bracket and the housing of the ground zero-gravity air flotation simulator.
