[0048] Specific embodiments are given below to introduce the technical solution of the present application in detail.

[0049] Figure 1 This is a schematic diagram of a transport condition simulator shown in an exemplary embodiment of the present application. Figure 2 Based Figure 1 Schematic diagram of the simulator components in the transport condition simulator shown. Please also refer to Figure 1 and Figure 2 The transport condition simulator provided in this embodiment includes a simulator component 100, a sensor group 200 and a controller 300; the simulator component 100 includes a flight environment simulator 1, a ground environment simulator 2 and a temperature and humidity environment simulator 3 ( Figure 2 ), wherein,

[0050] The flight environment simulator 1 comprises a base 11, an elevator 12, a container 13, a first wing-shaped cantilever beam 14 and a second wing-shaped cantilever beam 15 respectively arranged on both sides of the container 13, and a first engine 16 installed on the first wing-shaped cantilever beam 14 and a second engine 17 installed on the second wing-shaped cantilever beam 15; wherein one end of the elevator 12 is connected to the base 11 and the other end is connected to the container 13, and is used to control the lifting and lowering of the container 13;

[0051] The bottom of the container 13 has a wheel 131, and the base 11 has a groove 111; the ground environment simulator 2 includes a cylindrical road simulator 21; the cylindrical road simulator 21 is arranged in the groove 111; the cylindrical road simulator 21 can rotate in the groove 111 when the wheel 131 runs on it, so as to simulate the situation that the wheel 131 runs on the road surface with different degrees of bumpiness;

[0052] The temperature and humidity environment simulator 3 is used to provide a specified temperature environment and humidity environment for the container 13;

[0053] The controller 300 is used to control the simulator component 100 to simulate any actual transportation condition acquired in advance; wherein the actual transportation condition is a transportation condition described by a combination of mechanical motion, vibration, temperature and humidity;

[0054] The sensor group 200 is disposed inside the container 13, and is used to measure the simulated transportation environment simulated by the simulator component 100 in real time, and send the simulated transportation environment to the controller 300;

[0055] The controller 300 is further used to adjust the simulator component 100 based on the feedback of the simulated transportation environment and the actual transportation conditions, so as to match the simulated transportation environment with the actual transportation conditions to simulate real transportation conditions.

[0056] It should be noted that the transport simulator provided by the present application is used to reproduce the transport conditions of the product during transportation. The product may be any product. Preferably, the product is a precision product with packaging, which needs to maintain good integrity during transportation to avoid damage. By using the transport condition simulator to simulate actual transport conditions, the state of the product under different transport conditions can be obtained, and then according to the obtained state, the packaging method, fixing method, transportation method, etc. of the product can be optimized to effectively ensure that the product maintains good integrity and performance under various transport environments.

[0057] Please refer to Figure 2The simulator assembly 100 includes a flight environment simulator 1, a ground environment simulator 2 and a temperature and humidity environment simulator 3 ( Figure 2 (not shown), wherein the flight environment simulator 1 includes a base 11, an elevator 12, a container 13, a first wing-shaped cantilever beam 14 and a second wing-shaped cantilever beam 15 respectively arranged on both sides of the container 13, and a first engine 16 installed on the first wing-shaped cantilever beam 14 and a second engine 17 installed on the second wing-shaped cantilever beam 15; wherein one end of the elevator 12 is connected to the base 11 and the other end is connected to the container 13, and is used to control the lifting and lowering of the container 13.

[0058] It should be noted that the base 11 is the basic support part of the entire simulator assembly 100. The base 11 can provide stable support for the elevator 12. The elevator 12 is set on the base 11, and one end of the elevator 12 can be firmly connected to the connection part on the base 11, so that during the lifting and lowering process of the elevator 12, there will be no loosening or movement. The elevator 12 moves up and down through its own control, and then controls the container 13 connected at the other end to move up and down. Through the firm connection with the base 11, the container 13 will not have an unexpected tilting effect during the lifting process, ensuring the accuracy of the simulation.

[0059] It should be noted that the transportation condition simulator provided in the present application can simulate the take-off and landing, bumps, and the product handling process and the falling of the product during the handling process of an airplane by controlling the lifting and lowering of the elevator 12 .

[0060] Specifically, for example, by precisely controlling the lifting speed and height change of the elevator 12, the take-off and landing process of an aircraft can be simulated. In specific implementation, different lifting curves can also be set, such as slow rise and fast descent, to simulate different types of flight operations. Furthermore, by setting random vibration frequencies and amplitudes, turbulence in different flight environments, such as unstable airflow, can be simulated. In addition, for example, tiny vibrations can be introduced to simulate the handling process of a product; further, the elevator 12 can be made to fall suddenly to simulate the falling of a product during handling.

[0061] Optionally, in one possible implementation, the lift 12 may be a hydraulic lift.

[0062] It should be noted that when simulating the transportation conditions, the product to be tested is placed inside the container 13. The container 13 for placing the product to be tested has good heat insulation performance and is a sealed box. In this way, it can ensure that the temperature environment inside the container 13 is relatively stable, and foreign substances enter the container 13, reducing the damage to the product to be tested by foreign substances, so as to simulate the protection of precision products when transporting products in harsh environments.

[0063] Please continue to refer to Figure 2 A first wing-shaped cantilever beam 14 and a second wing-shaped cantilever beam 15 are also provided on both sides of the container 13. The first wing-shaped cantilever beam 14 and the second wing-shaped cantilever beam 15 are of the same size and shape, so that the flight environment simulator 1 can maintain balance during the simulation process. When simulating the flight state, the container 13 is more evenly subjected to the force of the air.

[0064] It should be noted that the wing-shaped cantilever beam (the wing-shaped cantilever beam specifically refers to the first wing-shaped cantilever beam 14 and the second wing-shaped cantilever beam 15) is usually a single plane structure, and the cross section may be trapezoidal or rectangular; further, the upper surface of the wing-shaped cantilever beam may be smoother to reduce air resistance, and the lower surface may have a certain curvature to form lift. In addition, the wing-shaped cantilever beam is usually made of lightweight and high-strength materials, such as carbon fiber or aluminum alloy, to improve strength and reduce weight.

[0065] Furthermore, a first engine 16 is installed below the first wing-shaped cantilever beam 14, and a second engine 17 is installed below the second wing-shaped cantilever beam 15. In a possible implementation, the first engine 16 and the second engine 17 are the same, and the two identical engines can ensure that the power and vibration effects generated by the engines act evenly on the container 13, so that the forces on the left and right sides of the container 13 in the forward direction are symmetrical and stable, so that the flight environment simulator 1 can simulate the force conditions under a more realistic flight state.

[0066] It is understandable that the transport condition simulator can simulate vibrations of different modes by controlling the rotation speeds of the first engine 16 and the second engine 17 , or controlling the positions of the engines on the wing-shaped cantilever beam.

[0067] It should be noted that, in order to simulate different transportation conditions, the engine speed and the engine position can be set according to actual needs, and are not limited here. For example, when the engine speed is low, a slight low-frequency vibration can be generated to simulate the slight shaking of the aircraft in a stable driving state; when the engine speed is high, a strong vibration can be generated to simulate the violent vibration of the aircraft when taking off, landing, or encountering strong airflow.

[0068] Furthermore, the engine may be arranged on a side close to the container 13 to simulate a local strong vibration effect, or the engine may be moved to a side away from the container 13 to simulate an overall vibration effect. Figure 3 This is a schematic diagram showing the position of the engine on the wing-shaped cantilever beam according to an exemplary embodiment of the present application. Figure 3 , Figure 3 In the middle (A) figure, the engine is arranged on a side close to the container 13. Figure 3 In FIG. 1 (B), the engine is arranged on a side away from the container 13, and by controlling the position of the engine on the wing-shaped cantilever beam, vibrations of different modes can be simulated.

[0069] For further information, please refer to Figure 2 A wheel 131 is also provided at the bottom of the container 13, and a groove is provided on the base 11; the ground environment simulator 2 includes a cylindrical road simulator 21; and the cylindrical road simulator 21 is arranged in the groove.

[0070] Figure 4A A diagram showing the relationship between a cylindrical road simulator and a wheel according to an exemplary embodiment of the present application; Figure 4B The schematic diagram of the cooperation between the cylindrical road simulator and the wheel is shown in an exemplary embodiment of the present application. Referring to FIG4 , the cylindrical road simulator 21 can rotate in the groove when the wheel 131 runs on it, so as to simulate the situation that the wheel 131 runs on the road with different degrees of bumps.

[0071] Specifically, Figure 5 This is a schematic diagram of a cylindrical road simulator shown in an exemplary embodiment of the present application. Figure 5 The cylindrical road simulator 21 includes a plurality of sub-cylinders, each of which has different texture patterns and is used to simulate roads with different degrees of bumpiness. Figure 5 In the example shown, the cylindrical road simulator 21 is composed of six sub-cylinders, each of which contains a different texture pattern. Figure 5 In the example shown, along the length direction of the groove 111, from left to right, the texture patterns on each sub-cylinder become smoother and smoother, which can simulate a bumpy road and a smooth road in turn.

[0072] In specific implementation, by lifting and lowering the elevator 12, the wheel 131 can be brought into contact with the outer surface of a sub-cylinder in the cylindrical road simulator 21, that is, the wheel 131 can be placed on a sub-cylinder in the cylindrical road simulator 21 to simulate product transportation on the road surface corresponding to the sub-cylinder.

[0073] For further information, see Figure 2 It can be understood that the length direction of the groove is consistent with the length direction of the cylindrical road simulator 21, and the cylindrical road simulator 21 can move in the groove so that the wheel 131 is opposite to different sub-cylinders to simulate the situation of driving on different road surfaces.

[0074] Specifically, after completing the transportation simulation of a certain road surface, the wheel 131 can be raised by the lift 12 to move it away from the contact with the cylindrical road simulator 21, and then the cylindrical road simulator 21 can be moved to place a sub-cylinder with texture features corresponding to the road surface to be simulated at the bottom of the wheel 131, and then the lift 12 can be used to move the wheel 131 to contact the sub-cylinder to continue simulating the next road surface.

[0075] It is understandable that different texture features can be set on the sub-cylinder according to the road surface to be simulated, and this is not limited here. For example, in one embodiment, when a flat highway road surface needs to be simulated, a sub-cylinder with a relatively smooth texture feature can be set; in another embodiment, when a rugged mountain road needs to be simulated, a sub-cylinder with a relatively rough and irregular texture feature can be set.

[0076] Furthermore, the simulator component 100 also includes a temperature and humidity environment simulator 3 , which is used to provide a specified temperature environment and humidity environment for the container 13 .

[0077] Optional, Figure 6 This is a partial schematic diagram of a simulator assembly shown in an exemplary embodiment of the present application, please refer to Figure 6 ,exist Figure 6 In the example shown, the temperature and humidity environment simulator 3 is built inside the container 13; the temperature and humidity environment simulator 3 includes a heater, a cooler, a humidifier and a dehumidifier.

[0078] When the temperature inside the container 13 is adjusted by using a heater or a cooler, the air flow inside the container 13 can make the temperature environment inside the container 13 evenly distributed, effectively avoiding local overheating or overcooling inside the container 13; similarly, when the humidity inside the container 13 is adjusted by using a humidifier and a dehumidifier, the air flow inside the container 13 also helps the moisture to diffuse faster, thereby achieving rapid humidity control.

[0079] Furthermore, Figure 7 This is a partial schematic diagram of a simulator assembly according to another exemplary embodiment of the present application. Figure 7 ,exist Figure 7In the example shown, the temperature and humidity environment simulator 3 includes an air supplier, a heater, a cooler, a humidifier and a dehumidifier, wherein the air supplier is connected to the container 13 through an air pipe; the heater, the cooler, the humidifier and the dehumidifier are used to control the temperature and humidity of the gas supplied by the air supplier to the container 13.

[0080] Specifically, the air supplier is a temperature and humidity controlled air supplier, which is connected to the container 13 through an air pipe to provide air to the inside of the container 13. In addition, the air provided by the air supplier to the container 13 is temperature controlled by a heater and a cooler, and humidity controlled by a humidifier and a dehumidifier.

[0081] It should be noted that the air supplier can provide gases of different properties according to actual needs, which are not limited here. For example, in one embodiment, dry nitrogen can be provided to the interior of the container 13 to protect the precision products in the container 13 from chemical reactions with oxygen and moisture in the air; in another embodiment, pure argon or other inert gases can be provided to the container 13 to simulate certain products transported under oxygen-free conditions.

[0082] Furthermore, the heater can increase the temperature of the gas inside the container 13 to simulate the transportation environment in a high temperature environment; the cooler can reduce the temperature of the gas inside the container 13 to simulate the transportation environment in a low temperature environment. By flexibly adjusting the heater and the cooler, the gas temperature inside the container 13 can be controlled, and the transportation environment of precision products under various temperature conditions can be effectively simulated. In addition, the humidifier can increase the moisture content inside the container 13 to increase the internal humidity, thereby simulating humid transportation conditions. When it is necessary to simulate a dry transportation environment, a dehumidifier can be used to remove moisture from the gas and reduce the humidity.

[0083] It should be noted that, through the temperature and humidity environment simulator 3, the specific simulated environment inside the container 13 can be set according to actual needs, and it is not limited here. For example, in one embodiment, it is necessary to simulate a high temperature and high humidity transportation environment, and the heater and the humidifier can be used to operate together to simulate the transportation environment; in another embodiment, it is necessary to simulate a low temperature and dry transportation environment, and the cooler and the dehumidifier can be used to operate together to simulate the transportation environment.

[0084] The transport condition simulator provided in this embodiment can simulate various transport conditions to a great extent and improve the accuracy of transport condition simulation by setting the temperature and humidity environment simulator 3.

[0085] The specific implementation principle of the transportation condition simulator provided in this embodiment to simulate the transportation environment is introduced below:

[0086] Figure 8 This is a schematic diagram showing the implementation principle of a transport condition simulator for simulating a transport environment according to an exemplary embodiment of the present application.

[0087] Please refer to Figure 8 The transportation condition simulator provided in the present application also includes a sensor group 200 and a controller 300 .

[0088] The controller 300 is used to control the simulator component 100 to simulate any actual transportation condition acquired in advance; wherein the actual transportation condition is a transportation condition described by a combination of mechanical motion, vibration, temperature and humidity;

[0089] The sensor group 200 is disposed inside the container 13, and is used to measure the simulated transportation environment simulated by the simulator component 100 in real time, and send the simulated transportation environment to the controller 300;

[0090] The controller 300 is further used to adjust the simulator component 100 based on the feedback of the simulated transportation environment and the actual transportation conditions, so as to match the simulated transportation environment with the actual transportation conditions to simulate real transportation conditions.

[0091] It should be noted that the sensor group 200 at least includes a vibration sensor for testing vibration, a temperature sensor for testing temperature, and a humidity sensor for testing humidity.

[0092] Specifically, when the above-mentioned transportation environment simulator is used to simulate an actual transportation condition, the controller 300 sends a control instruction to the simulator component 100 to control the simulator component 100 to simulate the actual transportation condition.

[0093] It should be noted that the actual transportation conditions are transportation conditions described by a combination of mechanical movement, vibration, temperature and humidity.

[0094] It should be noted that the actual transportation conditions can be obtained from an extensive transportation log library, which records multiple actual transportation conditions, each of which is composed of a set of transportation information parameters collected by a set of physical sensors placed on various transportation routes around the world.

[0095] It should be noted that when simulating actual transportation conditions, the sensor group 200 and the controller 300 work together, and the controller 300 is used to control the simulator component 100. The sensor group 200 then performs real-time measurements of the simulated transportation environment simulated by the simulator component 100, and feeds back to the controller 300 through the sensor feedback line. Furthermore, the controller 300 can compare the simulated transportation environment with pre-set actual transportation conditions based on these sensor data, and adjust the simulator component 100 through feedback, so that the transportation environment simulated by the simulator component 100 is as close to the actual transportation conditions as possible, thereby achieving accurate simulation.

[0096] Referring to the previous description, it can be understood that the transport condition simulator can realistically reproduce the various environmental conditions and stress conditions of the product during actual transportation through the collaborative work of multiple subsystems, ensuring that every detail of the transportation process is reproduced, meeting the needs of high-precision transportation environment simulation.

[0097] The transport condition simulator provided in this embodiment, firstly, can accurately simulate a variety of complex typical environmental conditions in the transport process through the combination of a flight environment simulator, a ground environment simulator and a temperature and humidity environment simulator, and can test the stability and tolerance of products in different transport modes and extreme environments; secondly, through the coordinated cooperation of the sensor group and the controller, the sensor group can monitor the simulated transport environment in real time, and when the controller detects that the current simulated transport environment is inconsistent with the actual transport conditions, it can immediately adjust the parameters of the simulator component to ensure that the simulated environmental conditions simulated by the simulator component are as close to the actual conditions as possible, so that the accuracy of the simulation and the reliability of the simulation results can be guaranteed; in addition, through the flexible combination and adjustment of the various components in the simulator component, different transport modes can be simulated, and the simulation surface is wider; finally, by accurately simulating the actual transport conditions, problems that may affect product quality in the transport process can be discovered early, so that related problems can be rectified to reduce the risk of damage during transportation and ensure the quality of the final product.

[0098] Optionally, a storage platform for placing the product to be tested is provided at the bottom of the cavity of the container 13; wherein the storage platform can be inclined in the length direction and / or the width direction.

[0099] Specifically, a storage platform for placing the product to be tested is provided at the bottom of the cavity of the container 13. In order to simulate the tilting of the product caused by the bumps during transportation, the storage platform can be tilted in the length direction and / or the width direction. In specific implementation, the storage platform can be tilted in the length and width directions by different fixing methods, which are not limited here.

[0100] For example, Fig. 9This is a partial schematic diagram of a transport condition simulator shown in an exemplary embodiment of the present application, please refer to Fig. 9 ,exist Fig. 9 In the example shown in FIG. (A), the storage platform can be fixed to the bottom plate of the container 13 by a spring; further, Fig. 9 In the example shown in FIG. 2 (B), the four corners of the storage table can be fixed to the bottom plate of the container 13 by four cylinders respectively, so that the storage table can be tilted in the length and width directions by controlling the extension and contraction of the cylinders.

[0101] The transportation condition simulator provided in this embodiment enables the storage table to have a tilt function in the length direction and / or width direction. In this way, it can reproduce the changes in gravity caused by uneven roads or turning, acceleration, and deceleration of the vehicle during transportation, and can more realistically reflect the changes in the product's posture under complex transportation conditions, further improving the accuracy of the simulation.

[0102] Furthermore, corresponding to the above-mentioned embodiment of a transport condition simulator, the present application also provides a transport condition simulation method. The transport condition simulation method provided by the present application is introduced below:

[0103] Fig.10 This is a flow chart of a method for simulating transportation conditions according to an exemplary embodiment of the present application. Fig.10 The transportation condition simulation method provided in this embodiment is applied to the controller 300 in any one of the transportation condition simulators provided in the first aspect of the present application, and the transportation condition simulation method includes:

[0104] S1001. For any actual transport condition acquired in advance, control a simulator component in the transport condition simulator to simulate the actual transport condition; wherein the actual transport condition is a transport condition described by a combination of mechanical motion, vibration, temperature and humidity.

[0105] S1002: Obtain a simulated transportation environment simulated by the simulator component measured in real time by a sensor group in the transportation condition simulator.

[0106] S1003: Adjust the simulator component based on the feedback of the simulated transportation environment and the actual transportation condition to make the simulated transportation environment match the actual transportation condition, so that the transportation environment simulator simulates the real transportation environment.

[0107] Specifically, the sensor group 200 is installed inside the container 13 to monitor various parameters in the simulated transportation environment in real time, including vibration, temperature, humidity, tilt angle, etc. Further, the sensor converts the acquired data into digital signals and transmits them to the controller 300 for analysis.

[0108] The controller 300 generates target conditions based on the actual transportation conditions. The target conditions may include specific vibration modes, temperature and humidity ranges, tilt angles, etc., to form a benchmark model. Further, the controller 300 compares the real-time simulated transportation environment collected by the sensor with the actual transportation conditions, and analyzes the difference between the current simulated environment and the target conditions. For example, the error or deviation between the two can be calculated to determine whether the simulated environment meets expectations.

[0109] Further, according to the comparison result between the real-time simulated transportation environment and the target condition, the controller 300 formulates a corresponding adjustment strategy. For example, if the real-time simulated environment fails to reach the target condition, the controller 300 will generate an adjustment instruction to adjust the operation of the simulator component 100.

[0110] Furthermore, the controller 300 issues instructions to the simulator components 100 (such as the flight environment simulator 1, the ground environment simulator 2, and the temperature and humidity environment simulator 3) through the adjustment signal to adjust them. For example, the operating parameters of the vibration motor can be controlled to increase or decrease the intensity and frequency of the vibration to achieve the desired vibration level. For another example, the temperature and humidity in the container 13 can be adjusted in real time through the temperature and humidity environment simulator 3 to ensure that it is within the target range. For another example, the inclination angle of the storage table can be adjusted as needed to simulate various postures that may occur during transportation.

[0111] It should be noted that the above process forms a closed-loop feedback system, and the controller 300 continuously monitors the changes in the simulated environment, collects data in real time and compares it with the target conditions to ensure that the simulated environment continues to match the actual transportation conditions. In addition, this process may be iterated multiple times to ensure the accuracy and stability of the simulation.

[0112] The transportation condition simulation method provided in this embodiment, through the above-mentioned feedback adjustment process, through continuous feedback and adjustment, enables the transportation condition simulator to adapt to changes in various transportation environments in real time, so that the simulated transportation conditions reflect the actual situation as realistically as possible, which can improve the accuracy of the simulation and provide an important basis for subsequent packaging solution optimization and transportation solution optimization.

[0113] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
