Description
Technical Field
[0001] The present invention relates to the technical field of training equipment, and in particular to an astronaut training simulation device. Background Art
[0002] With the continuous progress and development of science and technology, our exploration of the universe is constantly deepening, and the exploration of extraterrestrial space is also inseparable from the development of manned space flight. Manned space flight refers to astronauts driving and riding manned spacecraft in space to engage in various round-trip flights for exploration, research, testing, production and military applications. Through the exploration of astronauts, precious extraterrestrial space data are transmitted back to us. Astronauts need to undergo arduous training before they can be qualified for manned space flight. Among them, overweight training is one of the important trainings. Astronauts need to experience overweight during the launch and return of spacecraft. Therefore, it is essential for astronauts to train their tolerance to overweight. Training for overweight tolerance is usually carried out through manned centrifuges.
[0003] In the prior art, the existing manned centrifuge equipment is usually directly controlled by the speed of the motor during the speed change process. The change process is fast and cannot simulate the change process well. At the same time, the speed change is basically controlled manually and cannot be changed randomly, which is not in line with the actual situation. At the same time, in real situations, overweight will be accompanied by certain vibrations. The existing manned centrifuge equipment can only perform overweight simulation, which makes the existing equipment unable to achieve better simulation. Summary of the invention

When the fixed seat rotates, it will also drive the rotating bevel gear to rotate around the first axis. The meshing of the rotating bevel gear and the fixed bevel gear will cause the third axis to rotate. The meshing of the third gear and the fourth gear will cause the fourth axis to rotate. The eccentric wheel will rotate through the transmission of the universal joint. When the eccentric wheel rotates, the crew cabin will shake together, thus simulating the vibration under the overweight state and giving astronauts a more realistic training environment. 4. The rotation speed of the eccentric wheel is determined by the rotation speed of the first axis, and the rotation speed of the eccentric wheel determines the vibration frequency of the crew cabin. The rotation speed of the first axis determines the magnitude of the hypergravity, that is, the vibration frequency of the crew cabin is determined by the magnitude of the hypergravity. In actual situations, the greater the hypergravity, the greater the acceleration of the spacecraft, and the vibration frequency will increase accordingly, thereby making the simulation effect of the training equipment better and making the training environment of astronauts closer to the real situation; 5. The setting of enclosures, annular grooves and stabilizing blocks ensures the stable rotation of the fixed seat, rotating arm and passenger compartment, thereby ensuring the stability of the equipment.

DETAILED DESCRIPTION
[0023] Reference Figure 1-6 , an astronaut training simulation device, comprising a hollow base 1, wherein a driving mechanism is arranged in the base 1; The driving mechanism includes a first shaft 2, which is rotatably connected to the base 1 through a bearing. One end of the first shaft 2 located in the base 1 is fixedly connected with a first gear 3 and a contact wheel 15. The top wall of the base 1 is fixedly connected with a driving motor 4 through a bracket. The driving motor 4 is a fixed-torque motor, which can output a fixed torque, and its rotation speed changes with the resistance it encounters during rotation. The output shaft of the driving motor 4 is fixedly connected with a second shaft 5, and the second shaft 5 is fixedly connected with a second gear 6, which is meshed with the first gear 3. A first sleeve 7 is fixedly connected with the side wall of the base 1, and a piston 8 is sealingly and slidably connected in the first sleeve 7. The side wall of the base 1 is fixedly connected with an electric push rod 9 through a bracket, and the output end of the electric push rod 9 is fixedly connected to the side wall of the piston 8. One end of the first shaft 2 located outside the base 1 is fixedly connected with a fixed seat 18, and the side wall of the fixed seat 18 is fixedly connected with a rotating arm 19. The driving mechanism also includes a second sleeve 10, which is fixedly connected to the inner wall of the base 1, and the second sleeve 10 is sealed and slidably connected to the third sleeve 11, and the third sleeve 11 is slidably connected to the connecting block 12, and a plurality of first springs 13 are fixedly connected between the connecting block 12 and the third sleeve 11, and an arc block 14 is fixedly connected to the side wall of the connecting block 12, and the second sleeve 10 and the first sleeve 7 are filled with hydraulic oil, and the second sleeve 10 and the first sleeve 7 are fixedly connected to a connecting pipe 16 through which the connecting pipe 16 is fixedly connected. A solenoid valve 17 is provided, and the solenoid valve 17 is a normally closed solenoid valve, which is opened by power. The solenoid valve 17 and the electric push rod 9 are connected to the PLC control circuit. The PLC control circuit can periodically and randomly control the extension length of the electric push rod 9 to make it continue to extend or shorten. At the same time, when the electric push rod 9 moves, the solenoid valve 17 is energized. When the electric push rod 9 stops moving, the solenoid valve 17 is synchronously de-energized. This is a prior art and will not be described in detail here. The PLC control circuit will cause the electric push rod 9 to periodically and randomly change its extension length. When the extension length of the electric push rod 9 changes, the solenoid valve 17 is energized and opened synchronously. At this time, the electric push rod 9 drives the piston 8 to move. The movement of the piston 8 will pump hydraulic oil into the second sleeve 10 or extract hydraulic oil from the second sleeve 10 through the connecting pipe 16, thereby changing the position of the third sleeve 11. When the position of the third sleeve 11 changes, the pressure between the arc block 14 and the contact wheel 15 will change. The change in pressure between the arc block 14 and the contact wheel 15 will change the friction resistance between the two, thereby changing the rotation resistance of the first shaft 2. After the rotation resistance of the first shaft 2 changes, its rotation speed will change. After the rotation speed of the first shaft 2 changes, the centrifugal force of the passenger cabin 29 changes accordingly, so that the size of the supergravity to which the astronauts are subjected changes, thereby completing the random change of the size of the supergravity to which the astronauts are subjected, simulating the random change of supergravity in actual conditions, making the training of astronauts more in line with actual conditions, and greatly improving the training effect.
[0024] It is worth mentioning that, when the extension length of the electric push rod 9 is changed, it needs to undergo a smooth movement process, so that the friction resistance between the arc block 14 and the contact wheel 15 is changed smoothly. Compared with the prior art, the motor speed is directly changed, so that the motor speed changes instantly, thereby making the hypergravity change process relatively short, and the hypergravity change process cannot be well simulated. The present invention can better simulate the hypergravity change process.
[0025] A vibration mechanism is provided at the fixed seat 18 and the rotating arm 19, and the vibration mechanism includes a fixed plate 20, the fixed plate 20 is fixedly connected to the lower surface of the fixed seat 18, the fixed plate 20 is rotatably connected to the third shaft 21 through a bearing, one end of the third shaft 21 is fixedly connected to the rotating bevel gear 22, and the other end is fixedly connected to the third gear 41, a fixed bevel gear 24 is fixedly connected to the upper surface of the base 1, the fixed bevel gear 24 is rotatably connected to the first shaft 2 through a bearing, and the fixed bevel gear 24 is meshed with the rotating bevel gear 22, the fixed seat 18 is provided with a mounting hole 25, and the fixed seat 18 and the rotating arm 19 are rotatably connected to a fourth shaft 26 through a bearing. One end of the fourth shaft 26 extends through the mounting hole 25 and is fixedly connected to the fourth gear 23. The other end extends through the fixed seat 18 and the outside of the rotating arm 19 and is fixedly connected to a universal joint 27. The fourth gear 23 is meshed with the third gear 41. The end of the universal joint 27 away from the fourth shaft 26 is fixedly connected to a fifth shaft 28. The fifth shaft 28 is fixedly connected to an eccentric wheel 30. The end of the fifth shaft 28 away from the universal joint 27 is rotatably connected to the passenger compartment 29 through a bearing. The universal joint 27 is as shown in FIG. Figure 2 As shown, through the connection of the universal joint 27, the eccentric wheel 30 is allowed to move in its plane while ensuring the driving of the fourth shaft 26. During the training process, the rotation of the fixed seat 18 will also synchronously drive the rotating bevel gear 22 to rotate around the first axis 2. Through the meshing of the rotating bevel gear 22 and the fixed bevel gear 24, the rotating bevel gear 22 is rotated, and the rotating bevel gear 22 drives the third gear 41 to rotate through the third shaft 21. The third gear 41 drives the fourth gear 23 meshed with it to rotate. The fourth gear 23 drives the fifth shaft 28 to rotate through the fourth shaft 26 and the universal joint 27. The rotation of the fifth shaft 28 will drive the eccentric wheel 30 to rotate. The rotation of the eccentric wheel 30 will cause it to vibrate continuously in its plane, thereby driving the crew cabin 29 to vibrate with it, thereby simulating the vibration of the spacecraft during the overweight process, so that the astronauts are placed in a training environment that is more in line with the actual situation, greatly improving the simulation effect of the equipment, thereby making the training effect better.
[0026] It is worth mentioning that when the rotation speed of the first shaft 2 changes, the rotation speed of the fixed seat 18 changes accordingly, so that the rotation speed of the rotating bevel gear 22 changes accordingly, and then the rotation speed of the third gear 41 driven by the rotating bevel gear 22 changes, and then through the meshing of the third gear 41 and the fourth gear 23 and the transmission of the fourth shaft 26 and the universal joint 27, the rotation speed of the eccentric wheel 30 is finally changed. The change in the rotation speed of the eccentric wheel 30 will change the vibration frequency of the passenger compartment 29. The faster the rotation speed of the first shaft 2, the higher the vibration frequency of the passenger compartment 29, and vice versa. This is more in line with the actual situation. The greater the supergravity, the faster the acceleration, the higher the vibration frequency, and vice versa, the smaller it is, which makes the simulation effect of the equipment better, and the adjustment process is fully automated, without manual intervention, which greatly improves the automation level of the equipment.
[0027] The rotating arm 19 is penetrated and fixedly connected with a functional block 31. The side wall of the functional block 31 close to the passenger compartment 29 is provided with two grooves 32. The functional block 31 is slidably connected with two groove blocks 33 through the grooves 32. A plurality of second springs 34 are respectively fixedly connected between the center positions on the left and right sides of the groove blocks 33 and the corresponding inner side walls of the grooves 32. A slider 35 is slidably connected in the groove blocks 33. Figure 4 As shown, a groove is opened in the groove block 33, and the slider 35 is slidably connected in the groove. A plurality of third springs 36 are fixedly connected between the upper and lower center positions of the slider 35 and the corresponding inner walls of the groove 32, respectively. The second spring 34 and the third spring 36 are located in the same plane, and the two are vertically arranged. A connecting column 37 is fixedly connected between the slider 35 and the passenger compartment 29. Through the arrangement of the functional block 31, the groove block 33 and the slider 35, it is connected to the passenger compartment 29 through the connecting column 37, ensuring that the passenger compartment 29 can remain stable when vibrating under the drive of the eccentric wheel 30, thereby providing a certain protection for the astronauts inside.
[0028] A baffle 38 is fixedly connected to the upper surface of the base 1. The setting of the baffle 38 prevents the meshing bevel gears and gears from being directly exposed to the outside world. The baffle 38 is provided with an annular groove 39. The baffle 38 is slidably connected to a stabilizing block 40 through the annular groove 39. The stabilizing block 40 is fixedly connected to the side wall of the fixed seat 18.
[0029] The contact area between the piston 8 and the hydraulic oil is smaller than the contact area between the second sleeve 10 and the hydraulic oil. Since the hydraulic oil cannot be compressed, the internal pressure is equal everywhere. From P=F / S, it can be seen that when the pressure is equal, the larger the contact area, the greater the pressure there. Therefore, after a certain force is applied at the piston 8, a greater force can be generated at the second sleeve 10. Therefore, when the same pressure is obtained, a smaller electric push rod 9 can be selected, which reduces the occupied area of the electric push rod 9 and reduces the equipment cost.
[0030] The number of teeth of the second gear 6 is smaller than that of the first gear 3. By setting the number of teeth of the second gear 6 and the first gear 3, a smaller rotational torque at the second gear 6 can generate a larger rotational torque at the first gear 3, thereby allowing the drive motor 4 to be selected with a smaller specification, thereby reducing the occupied area of the drive motor 4 and reducing the equipment cost.
[0031] The number of teeth of the third gear 41 is greater than that of the fourth gear 23. By setting the number of teeth of the third gear 41 and the fourth gear 23, the third gear 41 drives the fourth gear 23 to rotate faster, thereby accelerating the rotation of the eccentric wheel 30, thereby ensuring better vibration.
[0032] The cross section of the annular groove 39 is T-shaped, and the cross section of the contact portion of the stabilizing block 40 and the annular groove 39 is also T-shaped. The T-shaped structure allows the stabilizing block 40 to slide more stably in the annular groove 39 to avoid slipping, thereby ensuring the smooth operation of the equipment.
[0033] The outer surfaces of the arc block 14 and the contact wheel 15 are both covered with a rubber layer. The provision of the rubber layer can make the friction resistance between the two more obvious, so that the rotation speed of the first shaft 2 can be better changed through the friction resistance between the two.
[0034] In the present invention, the astronauts to be trained enter the crew cabin 29 and make corresponding preparations before starting training.
[0035] During training, the drive motor 4 is turned on, and the drive motor 4 drives the second gear 6 to rotate through the second shaft 5. The second gear 6 drives the first gear 3 meshing therewith to rotate. The rotation of the first gear 3 drives the first shaft 2 to rotate, and the first shaft 2 drives the rotating arm 19 to rotate, so that the crew cabin 29 rotates synchronously. The rotation of the crew cabin 29 and the centrifugal force of the rotation put the astronauts inside in an overweight state.
[0036] During the process, the PLC control circuit will cause the electric push rod 9 to periodically and randomly change its extension length. When the extension length of the electric push rod 9 changes, the solenoid valve 17 is synchronously energized and opened. At this time, the electric push rod 9 drives the piston 8 to move. The movement of the piston 8 will pump hydraulic oil into the second sleeve 10 or extract hydraulic oil from the second sleeve 10 through the connecting pipe 16, thereby changing the position of the third sleeve 11. When the position of the third sleeve 11 changes, the pressure between the arc block 14 and the contact wheel 15 will change. The change in pressure between the arc block 14 and the contact wheel 15 will change the friction resistance between the two, thereby changing the rotation resistance of the first shaft 2. After the rotation resistance of the first shaft 2 changes, its rotation speed will change. After the rotation speed of the first shaft 2 changes, the centrifugal force of the passenger cabin 29 will change accordingly, so that the magnitude of the supergravity to which the astronauts are subjected will change, thereby completing the random change of the magnitude of the supergravity to which the astronauts are subjected.
[0037] During the training process, the rotation of the fixed seat 18 will also synchronously drive the rotating bevel gear 22 to rotate around the first axis 2. The rotating bevel gear 22 is engaged with the fixed bevel gear 24, so that the rotating bevel gear 22 rotates. The rotating bevel gear 22 drives the third gear 41 to rotate through the third axis 21. The third gear 41 drives the fourth gear 23 engaged therewith to rotate. The fourth gear 23 drives the fifth shaft 28 to rotate through the fourth axis 26 and the universal joint 27. The rotation of the fifth shaft 28 will drive the eccentric wheel 30 to rotate. The rotation of the eccentric wheel 30 will cause it to vibrate continuously in its plane, thereby driving the crew cabin 29 to vibrate with it, thereby simulating the vibration of the spacecraft during the overweight process, so that the astronauts are placed in a training environment that is more in line with the actual situation.
[0038] When the rotation speed of the first shaft 2 changes, the rotation speed of the fixed seat 18 changes accordingly, so that the rotation speed of the rotating bevel gear 22 changes accordingly, and then the rotation speed of the third gear 41 driven by the rotating bevel gear 22 changes, and then through the meshing of the third gear 41 and the fourth gear 23 and the transmission of the fourth shaft 26 and the universal joint 27, the rotation speed of the eccentric wheel 30 is finally changed. The change in the rotation speed of the eccentric wheel 30 will change the vibration frequency of the passenger compartment 29. The faster the rotation speed of the first shaft 2, the higher the vibration frequency of the passenger compartment 29, and vice versa. This is more in line with the actual situation. The greater the supergravity, the faster the acceleration, the higher the vibration frequency, and vice versa, the smaller it is, so that the simulation effect of the equipment is better.
