Description

Technical Field

[0001] This application relates to the field of automotive passive safety testing, and in particular to a method, equipment, and medium for testing the impact resistance of a tank tipping protection device. Background Technology

[0002] In tanker vehicle accidents, safety accessories and loading / unloading attachments on the top of the tank are easily damaged by impact, leading to hazardous material leakage and serious hazards. Therefore, when the tank top accessories protrude from the tank body, a tipping protection device is installed to ensure that the tank top accessories are not damaged in the event of a vehicle rollover accident, thus preventing secondary hazards.

[0003] The strength of the overturning protection device is crucial, and relevant domestic standards have made clear requirements for it: GB 18564.1-2019 "Road Transport of Liquid Dangerous Goods Tank Vehicles Part 1: Technical Requirements for Metal Atmospheric Pressure Tanks" and GB 7258-2017 "Technical Conditions for Safe Operation of Motor Vehicles" require that the overturning protection device should be able to withstand the inertial force of twice the total mass of the vehicle multiplied by the acceleration due to gravity.

[0004] In related technologies, CN119442739A discloses "A method, equipment and medium for testing the strength of a tank overturning protection device". It studies the overturning angle of the overturning protection device to find the loading angle with the greatest stress and the greatest deformation to test the strength of the overturning protection device.

[0005] However, although this method takes into account the severe situation of the overturning protection device actually overturning, there is still a difference between the static pressure used in the detection method and the inertial force required in reality. The overturning of the overturning protection device is a dynamic process. When detecting the overturning protection device of the tank, factors such as the overturning height and the speed generated when the overturning protection device of the tank impact should be fully considered.

[0006] In view of this, there is an urgent need to provide a detection method that can fully consider factors such as the rollover height of the tank when it rolls over and the speed generated when the tank overturning protection device impacts it, so that the impact load during the detection process meets the requirement of twice the inertial force of the total mass of the vehicle corresponding to the tank, making the detection method more scientific, reasonable, accurate and reliable. Summary of the Invention

[0007] The purpose of this invention is to provide a method, equipment, and medium for testing the impact resistance of a tank overturning protection device. It fully considers factors such as the height of the tank when it overturns and the speed of the tank overturning protection device when an impact load is formed. Compared with static simulation, it can more realistically reflect the actual overturning situation. The testing method is more scientific, reasonable, accurate, and reliable, and has high guiding and application value for the strength testing of overturning protection devices.

[0008] Firstly, the method for testing the impact resistance of a tank tilting protection device provided in this application adopts the following technical solution:

[0017] Calculate the tilt angle γ when the overturning protection device rolls over, wherein the tilt angle γ = 180 - θ + φ;

[0018] Based on the loading angle, the compensation angle β is calculated, where the compensation angle β = γ - α;

[0019] The tilt angle of the experimental device model is adjusted based on the compensation angle.

[0020] Further, S2 includes:

[0023] Furthermore, S21 specifically includes:

[0024] S211. Based on the impact load, determine the height difference Δh between the centers of mass of the tank model before and after the rollover; where,

[0025]

[0026] Where, Δ s t is the static displacement generated by the tank overturning protection device when subjected to a static pressure of 2m1g; m1 is the maximum gross mass of the test vehicle, and m2 is the total mass of the tank.

[0027] S212. Set the initial height h1 of the tank model before it overturns;

[0028] S213. Based on the height difference Δh of the center of mass before and after the tank model overturns, the initial height h1 of the tank model before overturning, and the dimensions of the tank model and the overturning protection device model, the height h2 of the test device model is calculated.

[0029] Furthermore, in S2, the rollover angular velocity of the overturning protection device model is ≤3° / min.

[0030] Furthermore, the overturning protection device model includes multiple protective parts disposed on the tank model;

[0031] In S2, when the overturning protection device model overturns and applies an impact load to the impacted part of the test device model, any one or more of the protection parts come into contact with the impacted part.

[0032] Further, S5 includes:

The memory stores a computer program. When the processor executes the computer program, it implements the above-mentioned detection method.

[0039] Thirdly, this application provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the above-described detection method.

[0040] In summary, this application includes at least one of the following beneficial technical effects:

[0041] 1. This application constructs an analytical model to dynamically simulate the overturning situation of the overturning protection device. During the simulation, the test device model is adjusted to the loading position and loading angle so that the overturning protection device model can apply the required impact load to the test device model when overturning. It fully considers factors such as the height of the tank when it overturns and the speed generated when the tank overturning protection device impacts. Compared with static simulation, it can more realistically reflect the actual overturning situation and has high guiding value and application value for the strength testing of overturning protection devices.

[0042] 2. Based on the requirements of impact load, this application preliminarily determines the vertical distance between the test device model and the tank model according to the corresponding formula, so as to quickly locate the height of the test device model and the tank model. Then, the angle of the test device model is further adjusted and the position of the test device model is finely adjusted, which has the characteristics of high testing efficiency.

[0043] 3. This application, under the condition that the impact load meets the inertial force of twice the total mass of the vehicle corresponding to the tank, further takes into account the loading angle when the tank rolls over, so that the overturning protection device applies the impact load to the test device at the maximum deformation angle, and can set part of the overturning protection device to contact the test device. It fully considers the severe situation when the tank rolls over, and puts forward more scientific and rigorous collision requirements for the test method, so that the overturning protection device that meets the strength requirements can cope with various overturning situations and provide better protection for the tank.

[0051] It should also be further understood that the term "and / or" as used in this application refers to any combination of one or more of the listed items, and all possible combinations thereof.

[0052] A method for testing the impact resistance of a tank tilting protection device, referring to... Figure 1 This includes the following steps:

[0053] S1. Construct an analysis model, which includes a test device model, a tank model, and a tilt protection device model installed on the tank model.

[0054] The tank model and overturning protection device model can cover various forms and can be constructed according to the specific structure of the actual overturning protection device (e.g., based on actual drawing dimensions). The test device model can be simplified, for example, in block or plate form, as shown below. Figure 2 As shown.

[0055] Based on this, various forms of mainstream tank bodies and overturning protection devices currently on the market can be adopted. Extensive simulations can be conducted to generate corresponding graphs for various types of protection devices and tanks of different specifications. The information obtained from these graphs includes strength parameters such as elevation difference and stress-strain. This will create a series of graphs corresponding to various tank types and their input conditions, enabling the rapid acquisition of corresponding analysis models when subsequently switching to strength testing of other types of overturning protection devices.

[0056] S2. Adjust the relative position of the test device model and the tank model so that the overturning protection device model overturns and applies an impact load to the impacted part of the test device model; wherein, the impact load is an inertial force equal to twice the total mass of the vehicle model corresponding to the tank.

[0057] By dynamically simulating the rollover situation of the overturning protection device, dynamic impact loads are applied to the impacted part, which can more realistically reflect the actual rollover situation compared to static simulation.

[0058] In this embodiment, in S2, the rollover angular velocity of the overturning protection device model is ≤3° / min.

[0059] It should be noted that the rollover angular velocity causes the tank model to tilt. A lower rollover angular velocity reduces the impact on the overturning protection device when the tank model is about to roll over. The tank model rolls downward at the critical position when it is about to roll over.

[0060] It should also be noted that in other embodiments, the rollover angular velocity can be further increased so that the tank model has a certain initial velocity when it rolls over, thereby adjusting the impact load by adjusting the initial rollover velocity of the tank.

[0061] Furthermore, this application does not specifically limit the device for tilting the tank. In this embodiment, the tank is rotated to the critical position of tipping over by a tipping platform set at the bottom of the tank. The tipping platform has a push plate that drives the tank to rotate. The push plate can be driven by a motor or pushed by a hydraulic cylinder.

[0062] In this embodiment, S2 specifically includes:

[0063] S21. Adjust the vertical distance between the test device model and the tank model until the overturning protection device model applies an impact load to the test device model.

[0064] Based on the known requirements of the impact load, the vertical distance between the test device model and the tank model is initially determined according to the corresponding formula, so as to quickly locate the height of the test device model and the tank model and improve the testing efficiency.

[0065] Correspondingly, S21 specifically includes:

[0066] S211. Based on the impact load, determine the height difference Δh between the centers of mass of the tank model before and after the rollover; where,

[0067] Specifically, in the rollover test, the rollover protection device must ensure that the impact load is equal to twice the total mass of the vehicle multiplied by the acceleration due to gravity when it collides with the impact block. That is:

[0068] F1 = 2G1

[0069]

[0070] F1 = F2

[0071] Organized

[0072]

[0073] Simplify to get

[0074]

[0075] Where F1 is the specified impact load, F2 is the actual impact load, Δh is the vertical distance the tank's center of mass falls, and Δ s t is the static displacement generated by the tank overturning protection device when subjected to a static pressure of 2m1g; v is the overturning speed of the tank when it overturns; m1 is the maximum gross mass of the test vehicle; and m2 is the total mass of the tank.

[0076] S212. Set the initial height h1 of the tank model before it overturns.

[0077] S213. Based on the height difference Δh of the center of mass before and after the tank model overturns, the initial height h1 of the tank model before overturning, and the dimensions of the tank model and the overturning protection device model, the height h2 of the test device model is calculated.

[0078] Based on the overturning trajectory of the tank model and the required height difference Δh, the relative positions of the center of mass of the tank model before and after overturning are obtained by using the similar trigonometric calculation formula. On this basis, the initial height of the tank model before overturning is determined. Furthermore, based on the dimensions of the tank model and the overturning protection device model, the height h2 of the test device model can be obtained. h2 is the height position where the bottom of the tank model contacts the test device model platform after overturning.

[0079] Because the tank model needs to be repeatedly tilted and then reset, and because the tank model has a large mass, movement is difficult in actual experiments. Therefore, in this embodiment, the initial height h1 of the tank model is kept constant, while the height h2 of the test device model is adjusted. In other embodiments, the initial height h1 of the tank model can also be adjusted; or, both the initial height h1 of the tank model and the height h2 of the test device model can be adjusted simultaneously.

[0080] S22. Adjust the lateral distance between the test device model and the tank model so that the impact load is applied to the impacted part.

[0081] During the test, the location where the overturning protection device was subjected to impact load when it overturned was standardized. The location of the impacted part corresponded to the sensor on the actual test device. In the actual test, the sensor of the test device was impacted to sense the strain and stress of the overturning protection device. The location of the impacted part was obtained for subsequent actual testing.

[0082] In addition, the overturning protection device model includes multiple protective parts installed on the tank model; in S2, when the overturning protection device model overturns and applies an impact load to the impacted part of the test device model, any one or more protective parts come into contact with the impacted part.

[0083] The number of protective parts is set according to the actual situation. In this embodiment, the number of protective parts is set to three. When the overturning protection device applies an impact load to the impacted part, one protective part contacts the impacted part. This method of partially contacting the impacted part with the overturning protection device takes into account the tilting situation that occurs during the actual rollover process, so as to simulate a more realistic and severe rollover situation and put forward more scientific and rigorous collision requirements for the overturning protection device. The stress-strain diagram obtained from the simulation can be found in [reference needed]. Figure 3 .

[0084] In another embodiment, two protective parts may come into contact with the impacted part; in other embodiments, three protective parts may come into contact with the impacted part simultaneously.

[0085] It should be noted that the position of the impacted part needs to be adjusted accordingly for the above three contact methods. For example, when the impacted part is only in contact with some of the protective parts, the impacted part should protrude from the platform of the test device model, so that the sensor of the impacted part forms a gap with the platform of the test device.

[0086] S3. Obtain the location of the impacted part of the test device model when the impact load meets the requirements.

[0087] S4. Adjust the tilt angle of the test device model to the loading angle α, then reset the impacted part to bring the test device model to the loading position, and make the overturning protection device model roll over to apply impact load to the impacted part.

[0088] Among them, the loading angle α is the maximum deformation angle, which is obtained by static detection method. The principle is that the inertial force has a direction, and the magnitude of the component of the inertial force perpendicular to the top surface of the test device model changes with the tilt angle of the test device model. By adjusting the tilt angle, the maximum deformation angle is obtained, and a more severe collision environment is simulated.

[0089] It should be noted that adjusting the tilt angle of the test device model will cause the center point of the impacted part to shift in both the horizontal and vertical directions. The purpose of resetting the impacted part is to correct the deviation of the impacted part caused by adjusting the tilt angle.

[0090] Reference Figure 4 Adjusting the tilt angle of the experimental device model includes the following steps:

[0091] Obtain the initial angle φ of the test device model and the overturning angle θ of the overturning protection device;

[0092] Calculate the tilt angle γ when the overturning protection device rolls over, where the loading angle γ = 180 - θ + φ;

[0093] Based on the loading angle, the compensation angle β is calculated, where the compensation angle β = γ - α;

[0094] The tilt angle of the experimental device model is adjusted based on the compensation angle.

[0095] Taking a loading angle of 45°, an antenna angle of φ = 0°, and a side-flipping angle of θ = 120° as an example, the tilt angle γ = 60° is calculated, and the compensation angle β = 15° is further calculated.

[0096] In this case, rotate the top surface of the test device clockwise by 15° to complete the adjustment of the tilt angle. After the tilt angle is adjusted, the position of the impacted part changes. Then, lower the position of the impacted part to the position of the impacted part in step S3 to complete the final adjustment of the test device.

[0097] It should be noted that, in this embodiment, in order to facilitate the subsequent actual strength test of the tank tilting device, the tilt angle of the test device is adjusted to complete the adjustment.

[0098] S5. Obtain the loading position and loading angle of the test device model, and perform strength testing on the tank overturning device.

[0099] Prior to S5, a structural strength finite element analysis was performed on the analysis model to obtain the stress, strain, and displacement of the overturning protection device model when an impact load was applied to the impacted part.

[0100] By performing finite element analysis of structural strength, it is possible to promptly check for errors in the preceding steps and verify the method. If the verification is correct, the obtained parameters provide theoretical reference data for subsequent actual strength testing.

[0101] In this embodiment, S5 specifically includes the following steps:

[0102] S51. Obtain the test apparatus, tank, and overturning protection device installed on the tank, and adjust the test apparatus to the loading position and loading angle.

[0103] The test device includes a test platform and four telescopic legs hinged to the bottom of the test platform. By adjusting the four telescopic legs, the height and tilt angle of the test platform can be adjusted, so that the test device can be adjusted to the loading position and loading angle.

[0104] Based on this, a digital display inclinometer can be added to the test bench to detect the tilt angle of the test device in real time, so as to facilitate the adjustment and verification of the tilt status of the test device.

[0105] S52. Rotate the tank to cause the overturning protection device to fall onto the impact part of the test device, wherein sensors are distributed on the impact part, the tank, and the overturning protection device.

[0106] S53. Based on sensors, obtain the impact load, strain, and stress magnitude of the overturning protection device.

[0107] The sensor detects the magnitude of the inertial force. In this embodiment, the sensing surface on the impacted part is set as a pressure sensor, and the sensors on the tank and the overturning protection device are set as strain gauges or strain rosettes. Based on the known magnitude and direction of the rollover speed, the magnitude of the component of the inertial force perpendicular to the top surface of the test device model is obtained by the pressure sensor. The magnitude of the inertial force is obtained to detect whether the impact load meets the requirements. The stress curve and strain curve are obtained by arranging strain gauges or strain rosettes on the tank and the overturning protection device.

[0108] S54. Determine whether the overturning protection device meets the strength requirements.

[0109] When determining whether the test meets the requirements, the strain and stress of the overturning protection device are used as the main evaluation data. If both data do not exceed the specified requirements, further observation is made to see whether the overturning protection device intrudes into the valve body accessory at the top of the tank. Water is injected into the tank to test the tank's sealing performance to check whether the tank is well sealed, and the overturning protection device is further evaluated.

[0110] Furthermore, in order to better implement the above-mentioned testing method, this application provides an electronic device, including a testing device, a memory, and a processor. The testing device is used to adjust the impact load of the overturning protection device, the memory stores a computer program, and when the processor executes the computer program, it implements the above-mentioned testing method.

[0111] The memory may include a program storage area and a data storage area, wherein the program storage area may store instructions for implementing the above detection method, and the data storage area may store data involved in the above detection method.

[0112] The processor may include one or more processing cores. The processor executes or runs instructions, programs, code sets, or instruction sets stored in memory, and calls data stored in memory to perform various functions and process data as described in this application.

[0113] The processor can be at least one of the following: application-specific integrated circuit, digital signal processor, digital signal processing device, programmable logic device, field-programmable gate array, central processing unit, controller, microcontroller, and microprocessor. It is understood that, for different devices, the electronic device used to implement the above-described processor functions can also be other types, and the embodiments of this application do not specifically limit this.

[0114] In addition, this application provides a computer-readable storage medium on which a computer program is stored, and when the computer program is executed by a processor, it implements the above-mentioned detection method.

[0115] Computer-readable storage media are configured according to actual needs, and may include, for example, USB flash drives, external hard drives, read-only memory (ROM), random access memory (RAM), magnetic disks, or optical disks.

[0116] The implementation principle of this application embodiment is as follows:

[0117] An analytical model was constructed to dynamically simulate the rollover of the overturning protection device. During the simulation, the test device model was adjusted to the loading position and loading angle so that the overturning protection device model could apply the required impact load to the test device model when it rolls over.

[0118] A structural strength finite element analysis was performed on the analysis model to obtain the impact load, strain, and stress magnitude of the overturning protection device model when an impact load was applied to the impacted part.

[0119] After dynamic simulation and structural strength finite element analysis are completed, the overturning protection device is then subjected to actual strength testing. The strength of the overturning protection device is evaluated based on stress curves, strain curves, and visual observation of whether the overturning protection device intrudes into the valve components at the top of the tank and the sealing performance of the tank.

[0120] The testing method simulates the most severe overturning conditions of the overturning protection device and conducts dynamic tests on it. It proposes more scientific and rigorous collision requirements, enabling the overturning protection device that meets the strength requirements to cope with various side-tipping situations and provide better protection for the tank. The testing method has high guiding and application value for the strength testing of overturning protection devices.

[0121] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
