Description

Technical Field

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

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

[0003] Typically, experimental requirements necessitate a protective casing attached to the exposed base of a ground-based zero-gravity flotation simulator to prevent violent collisions during operation, potentially damaging installed electromechanical equipment. The protective casing also ensures operator safety to a certain extent. Therefore, experiments involving ground-based zero-gravity flotation simulators require a reliable protective casing fixture to ensure a secure connection between the casing and the simulator base.

[0004] On the other hand, according to some special experimental requirements, such as using a ground-based zero-gravity flotation simulator to simulate the spatial movement of equipment such as airplanes, ships, and space shuttles, the base of the ground-based zero-gravity flotation simulator needs to be fixed with 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 adapts to the experimental simulation shell to ensure a close fit between the experimental simulation shell and the ground-based zero-gravity flotation simulator.

[0005] Although the prior art provides various devices and methods for securing 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 difficult 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

[0007] To solve the above problems, the present invention provides a ground zero-gravity air flotation simulator shell fixing bracket, which aims to provide a more stable, flexible and convenient installation method to adapt to the installation of ground zero-gravity air flotation simulator shells of different types and sizes.

The side plates are provided in a pair, respectively arranged on both sides of the middle plate, and the top plate is arranged above the middle plate.

[0010] The side panels are provided with a plurality of first side panel through holes, wherein the first side panel through holes are provided with first side panel connecting screws, and the side panels are fixedly connected to the top panel via the first side panel connecting screws;

[0011] The side panels are provided with a plurality of second side panel through holes, and the second side panel through holes are equipped with second side panel connecting screws. The side panels are fixedly connected to the middle panel via the second side panel connecting screws.

[0012] Preferably, a boss is provided in the middle of the side surface of the middle plate, and the boss is used for being installed in conjunction with the side plates.

[0013] 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 ground zero-gravity air flotation simulator base.

[0014] 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.

[0015] 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.

[0016] Preferably, the housing fixing bracket is provided with at least one pair of symmetrically mounted on the edges of the ground zero-gravity air flotation simulator mounting plate.

[0017] Preferably, the top plate is in a contoured shape designed according to the outer shape of the shell, and the shell fixing bracket is relatively tightly connected to the shell of the ground zero-gravity air flotation simulator.

[0018] 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 various components are tightly connected. The middle plate is designed with a boss, a stepped plane, and a fine-tuning plane straight slot, which provides 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. The shell connection threaded hole or the shell connection straight slot on the top plate improves the connection reliability between the shell fixing bracket and the shell of the ground zero-gravity air flotation simulator. The present invention solves the problem of fixing the shell of a ground zero-gravity air flotation simulator in a simple and easy-to-assemble manner, and has significant practical value.

[0026] The technical solutions of the present invention are further described below through the accompanying drawings and embodiments. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values described in these embodiments do not limit the scope of this application.

[0029] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0030] Unless otherwise defined, technical or scientific terms used in the present invention shall have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs.

[0031] Taking the ground motion simulation test experiment of a space shuttle as an example, the present invention 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.

[0032] The ground zero-gravity air flotation simulator 9 used in the space shuttle ground motion simulation test experiment can achieve two-dimensional motion in the horizontal plane on the air flotation platform through a plane support air foot 91 and an air supply system 92 .

[0033] In order to firmly and quickly fix the outer shell of the simulation model of the space shuttle on the base of the ground zero-gravity air flotation simulator 9, a ground zero-gravity air flotation simulator outer shell fixing bracket 1 is provided, including a top plate 2, side plates 3 and a middle plate 4. A pair of side plates 3 are provided, which are respectively arranged on both sides of the middle plate 4, and the top plate 2 is arranged above the middle plate 4.

[0034] like Figure 1 As shown, it can be seen that the overall structure of the shell 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.

[0035] Furthermore, the top plate 2 is provided with a plurality of top plate through holes 21 , and the top plate through holes 21 are equipped with corresponding top fixing screws 22 , and the top plate 2 is fixedly connected to the middle plate 4 via the top fixing screws.

[0036] The side panels 3 are provided with a plurality of first side panel through holes 31 , and the first side panel through holes 31 are provided with first side panel connecting screws 33 . The side panels 3 are fixedly connected to the top panel 2 via the first side panel connecting screws 33 .

[0037] The side panels 3 are provided with a plurality of second side panel through holes 32 , and the second side panel through holes 32 are provided with second side panel connecting screws 34 . The side panels 3 are fixedly connected to the middle panel 4 via the second side panel connecting screws 34 .

[0038] 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 fitting with the side plate 3 for installation.

[0039] The middle plate 4 has a boss 5, which is connected to the side plate 3. The lower part is provided with a stepped surface 6 and the upper part is provided with a flat straight slot 61 for fine-tuning 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.

[0040] 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 shell fixing bracket 1 to the base of the ground zero-gravity air flotation simulator 9 .

[0041] The flat straight slot 61 on the housing fixing bracket 1 allows for flexible fine-tuning of the relative positions of the housing and the mounting plate of the ground zero-gravity air flotation simulator 9, thereby improving assembly accuracy.

[0042] Furthermore, a plurality of shell connection threaded holes 7 or shell connection straight slots are provided on the top plate 2. The shell connection threaded holes 7 or shell connection straight slots are used for simulating external connection of two adjacent parts of the space shuttle. The shell connection threaded holes 7 or shell connection straight slots are equipped with shell connection screws 71.

[0043] The shell connection threaded holes 7 or the shell connection straight slots 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.

[0044] 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 .

[0045] Furthermore, the top plate 2 is shaped 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.

[0046] Specifically, by adjusting the relative positions of the outer shell fixing bracket 1 and the front and rear mounting platforms of the ground-based zero-gravity air flotation simulator 9, the outer shell fixing bracket 1 is ensured to be tightly fitted and connected to the space shuttle simulation outer shell. The shape of the top plate 2 can be designed to conform to the outer shell, such as the outer shape of a space shuttle. For example, the top plate 2 can be designed to be arc-shaped or in the shape of a space shuttle, so that the outer shell fixing bracket 1 can be relatively tightly fitted and connected to the outer shell of the space shuttle.

[0047] 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 .

[0048] Among them, Figure 3 and Figure 4 As shown, a pair of fixing brackets are installed on the front of the circular mounting platform 93 for simultaneously connecting the shuttle head 94 and the shuttle middle 95, and a pair of shell fixing brackets 1 are installed on the rear of the circular mounting platform 93 for connecting the shuttle middle 95 and the shuttle tail 96.

[0049] In summary, the housing fixing bracket of a ground-based 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-based zero-gravity air flotation simulator. The design of the flat straight slot allows for fine-tuning and adjustment between the housing and the mounting plate of the ground-based zero-gravity air flotation simulator, ensuring 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-based zero-gravity air flotation simulator. The present invention solves the problem of fixing the housing of a ground-based zero-gravity air flotation simulator in a simple structure and easy to assemble manner, and has significant practical value.
