[0034] The core of the present application is to disclose a high-temperature superconducting electric suspension test method and system, which can study the operating conditions of high-temperature superconducting electric suspension trains in a static environment, thereby reducing the implementation cost.

[0035] Hereinafter, the embodiments will be described with reference to the accompanying drawings. In addition, the embodiments shown below do not have any limiting effect on the gist of the invention described in the claims. Furthermore, the entire contents of the configurations indicated in the following embodiments are not limited to what is necessary for the solution of the invention described in the claims. Note that, for the convenience of description, only the parts related to the invention are shown in the drawings. The embodiments in the invention and the features in the embodiments can be combined with each other without conflict.

[0036] As shown in Figure 1 The embodiment of the present application discloses a high-temperature superconducting electrically levitated vehicle test system, referred to as a test system, which can include: a high-temperature superconducting electrically levitated vehicle 100, a vehicle carrying platform 200, a driving device 300, a coil module 400, and a control device.

[0037] The high-temperature superconducting electrically levitated vehicle 100 includes superconducting magnets 110 arranged on both sides of the vehicle body. Specifically, the superconducting magnets 110 are fixed to both sides of the levitation frame of the high-temperature superconducting electrically levitated vehicle 100 through fasteners.

[0038] The vehicle carrying platform 200 is used to carry the high-temperature superconducting electrically levitated vehicle 100. Specifically, the length of the vehicle carrying platform 200 is the length of the high-temperature superconducting electrically levitated vehicle 100 plus a first predetermined amount, which can be 1000 mm. The width of the vehicle carrying platform 200 is the width of the high-temperature superconducting electrically levitated vehicle 100 plus a second predetermined amount, which can be 100 mm.

[0039] The driving device 300 is in driving connection with the vehicle carrying platform 200 to drive the high-temperature superconducting electrically levitated vehicle 100 to rise and fall, so as to adjust the sinking amount of the superconducting magnets 110 and the coil module 400. It should be noted that the sinking amount here refers to the distance between the center line of the superconducting magnets 110 and the center line of the coil module 400, and different sinking amounts correspond to different levitation speeds.

[0040] Optionally, the vehicle carrying platform 200 includes a platform body 210 and a carrying area 220. The carrying area 220 is arranged on the platform body 210 and is arranged on both sides of the platform body 210, similar to a track. The support wheels of the high-temperature superconducting electrically levitated vehicle 100 abut against the carrying area 220. Specifically, a wheel stop is arranged on the carrying area 220 to limit the support wheels of the high-temperature superconducting electrically levitated vehicle 100. The carrying area 220 located on both sides of the platform body 210 and the platform body 210 form a hollow area. The hollow area is arranged to avoid the speed positioning system. The width of the hollow area is the width of the high-temperature superconducting electrically levitated vehicle 100 minus a third predetermined amount, which can be 500 mm. The initial thickness of the hollow area is 220 mm.

[0041] Exemplary, Figure 2 A structural schematic diagram of a vehicle carrying platform is shown, in combination with Figure 2 As shown, the driving device 300 is arranged on the platform body 210 and at the bottom of the carrying area 220, and is in driving connection with the carrying area 220, so as to drive the carrying area 220 to lift, and further drive the high-temperature superconducting electrically suspended vehicle 100 to lift.

[0042] The coil module 400 is arranged on both sides of the vehicle carrying platform 200, and interacts with the superconducting magnet 110. The strong magnetic field generated by the superconducting magnet 110 is opposite to the direction of the magnetic field generated by the coil module 400, and the two magnetic fields generate repulsive force. When the repulsive force is greater than the weight of the vehicle, the vehicle will float up. When the vehicle is displaced downward, the distance between the superconducting magnet 110 and the coil module 400 decreases, and the current increases, so that the levitation force increases, and the vehicle automatically returns to the original levitation position.

[0043] Optionally, the coil module 400 comprises a coil mounting seat 410 and a coil unit 420, wherein the coil mounting seat 410 is arranged on both sides of the high-temperature superconducting electrically suspended vehicle 100, and the coil unit 420 is arranged on the coil mounting seat 410.

[0044] It should be noted that the system composed of the high-temperature superconducting electrically suspended vehicle 100 and the coil module 400 is a scaled-down test system of an actual train system, and the actual train system comprises a high-temperature superconducting electrically suspended engineering sample vehicle and a test line. The high-temperature superconducting electrically suspended engineering sample vehicle is close to an actual high-temperature superconducting electrically suspended train carrying passengers, that is, the size of the actual train is equal to the size of the engineering sample vehicle, and the size of the engineering sample vehicle is greater than the size of the vehicle 100, and the size difference between the engineering sample vehicle and the vehicle 100 is large, that is, the size of the corresponding device of the test system matched with the vehicle 100 in the present application is also much smaller than the size of the test line. The present application uses a test system with a smaller size to simulate and test the running state of the engineering sample vehicle, so as to reflect the running state of the actual train, and reduce the test implementation cost.

[0045] The control device is electrically connected with the coil module 400 and the driving device 300 respectively, by changing the current amplitude and frequency of the coil module 400, the levitation force of the high-temperature superconducting electrically suspended vehicle 100 can be changed, the levitation speed is changed, different levitation speeds correspond to different sinking amounts of the superconducting magnet 110 and the coil module 400, the control device controls the driving device 300 to rise and fall according to the levitation speed of the high-temperature superconducting electrically suspended vehicle 100, so that the sinking amount of the superconducting magnet 110 and the coil module 400 matches the levitation speed. By changing the current amplitude and frequency of the coil module 400, and then changing the size of the levitation force, the running condition of the high-temperature superconducting electrically suspended vehicle 100 can be simulated. In the running direction of the vehicle, the high-temperature superconducting electrically suspended vehicle 100 is in a static state, and the running condition of the high-temperature superconducting electrically suspended vehicle 100 is simulated by applying a dynamic levitation force.

[0046] On the basis of the above, Figure 3 is a flowchart of a high-temperature superconducting electrically suspended test method according to an embodiment of the application, which can be applied to the test system described above. As shown in Figure 3 , the method can include the following steps:

[0047] Step S101, obtaining test parameters from the test requirements of the high-temperature superconducting electrically suspended engineering sample vehicle.

[0048] The test parameters correspond to the test conditions.

[0049] Step S102, determining the test parameters corresponding to the test parameters according to the pre-established parameter mapping relationship between the test system and the actual train system.

[0050] It should be noted that the test parameters are applicable to the actual train system composed of the engineering sample vehicle and the test line, which are system input parameters during testing; the test system and the actual train system have a certain mapping relationship, according to which the test parameters applicable to the test system can be obtained, which are called test parameters, as input parameters of the test system, thereby providing a basis for determining the running state of the engineering sample vehicle under the above test conditions.

[0051] The parameter mapping relationship can be established according to a first mapping relationship and a second mapping relationship, the first mapping relationship is a mapping relationship between the test system and an ideal test system, and the second mapping relationship is a mapping relationship between the ideal test system and the actual train system; the ideal test system is constructed by using a dimensionless quantity method and system parameters of the test system, and a shape matching degree of a force field function curve of the ideal test system and a force field function curve of the actual train system exceeds a preset limit, that is, the ideal test system established based on the test system is a similar system of the actual train system, and the two systems have similar solutions.

[0052] In step S103, a test state parameter of the high-temperature superconducting electric suspension vehicle 100 under the test working condition is obtained through the test system.

[0053] The test working condition corresponds to the test parameter.

[0054] In step S104, a test state parameter corresponding to the test state parameter is determined according to the parameter mapping relationship, as a state parameter of the high-temperature superconducting electric suspension engineering prototype vehicle under the test working condition.

[0055] In the case where the test parameter corresponds to the test parameter, the system state of the test system under the test working condition can reflect the system state of the actual train system under the test working condition to a certain extent, based on which, the simulation test task of the actual train system is realized by the test system with a large size difference from the actual train system. Moreover, the test system provided by the embodiment of the present application is equipped with a high-temperature superconducting electric suspension “force-magnetic-electric” dynamic simulation system, and the actual running working condition of the vehicle under different suspension speeds can be simulated by applying different currents to the fixed coil module 400 to make the vehicle statically suspended. Since the vehicle remains stationary in the running direction during the test, the safety of the test is high, and arbitrary speed and electromagnetic force test can be realized, and the matching relationship of the suspension, guiding gap and electromagnetic force under different suspension speeds can be simulated. In addition, the system only needs to construct a vehicle carrying platform 200 and a coil module 400 close to the size of the vehicle 100, without the need to construct a long-size test line, and the structure is simple, thereby reducing the implementation cost of the test.

[0056] The applicant has found that various high-temperature superconducting electric suspension systems often have consistent dynamic equations, which can be expressed as ; wherein i is a system identifier, i = 1 or 2; F(R) represents a field function of electromagnetic force and gravity varying with a spatial position R, R(t) is a solution of a dynamic equation of a function; μ represents a damping constant of the system, and m represents a vehicle weight in the system. On the basis of the above, if there is an approximate solution between the two systems, that is, the solution of system 1 can obtain the solution of system 2 after a space-time linear transformation, then the running condition of the other system can be obtained based on the test result of one of the systems.

[0057] On the basis of the above, it is assumed that R1(t) is the solution of system 1, and the solution kR1(st) obtained by space-time linear transformation is the solution of system 2, wherein k is a spatial reduction parameter, s is a time reduction parameter, and k and s are constants between the two systems. By substituting the solution R1(t) and the solution kR1(st) into the corresponding dynamic equations, the following equations are obtained: , In order to make the two equations hold at the same time, the following conditions need to be met: F1(R1) / m1 = F2(kR1) / m2, μ1 / m1 = μ2×k / (m2×s), s 2 =k. That is, the force field function curves of the two systems need to be the same.

[0058] Figure 4 The electromagnetic force characteristic curve diagrams of the test system and the actual train system are illustrated. As shown in FIG. 1, the curve forms of the high-temperature superconducting electric suspension vehicle and the engineering sample vehicle are close, but the numerical values are quite different. That is, due to the differences in size, vehicle weight, floating speed and the like of the two vehicles, the suspension force curve shapes of the two systems are different, and it is difficult to directly establish the mapping between the two systems. Figure 4

[0059] To solve the above problem, in one or more embodiments provided in the present application, the process of establishing the parameter mapping relationship between the test system and the actual train system can include the following steps S201-S208:

[0060] Step S201, constructing an initial ideal test system based on the system parameters of the test system.

[0061] The vehicle weight, the sinking amount when the maximum suspension force appears, the pole pitch and the resonance frequency of the initial ideal test system are consistent with the test system, and the suspension force of the initial ideal test system is represented as the product of the first dimensionless quantity (f r ) and the vehicle gravity (mg) of the initial ideal test system, that is, f z =f r ×mg, and the sinking amount of the initial ideal test system is represented as the product of the second dimensionless quantity (z r ) and the sinking amount (z m ​), i.e. z = z r × z m , the vehicle speed of the initial ideal test system is expressed as the product of the third dimensionless quantity (v r ) and the vehicle speed (v0) calculated based on the polar distance (τ) and the resonance frequency (f0) of the initial ideal test system, i.e. v x = v r × v0, the vehicle speed calculated based on the polar distance and the resonance frequency of the initial ideal test system is equal to one third of the product of the polar distance of the initial ideal test system and the resonance frequency of the initial ideal test system, i.e. v0= τ × f0 ÷ 3. It should be noted that the force field function can represent the relationship between the levitation force and the vehicle speed, and the relationship between the levitation force and the sinking amount, on the basis of which the vehicle forward speed v x can be converted into the alternating frequency of the magnetic field and the electromagnetic force suffered by the superconducting coil according to the ground coil period, which can be expressed as f (H Z ) = v x / P, P is the spatial period of the coil, wherein the spatial period corresponding to the resonance frequency is related to the polar distance. That is, when the initial ideal test system is constructed, the vehicle weight m, the position z max at which the maximum levitation force occurs, the polar distance τ and the resonance frequency f0 are non-adjustable variables, but the magnetic motive force of the permanent magnet and the resistivity of the ground coil can be adjustable variables, and the ideal test system configured by adjusting the adjustable variables has similar solutions with the actual train system.

[0062] Step S202, generating the force field function curve of the initial ideal test system according to the force field function curve of the test system.

[0063] Exemplarily, Figure 5 The original force field function curve of the initial ideal test system and the actual train system is shown, and the curve shapes of the initial ideal test system and the actual train system are different. In combination with the description above and the curve shown in Figure 4 , first, the electromagnetic force (i.e. the levitation force f z ) is mass-normalized according to F1(R1) / m1= F2(kR1) / m2, and f z / mg (i.e. the first dimensionless quantity) is taken as the dependent variable; then the ratio of the sinking amount z0 corresponding to the equilibrium position of the two systems to z m is the same, i.e. z / z m (i.e. the second dimensionless quantity) is taken as the independent variable, and the force field function curves of different systems are unified to the same scale, and correspondingly, v x / v0= 3v x / (τ × f0) (i.e. the third dimensionless quantity) can be taken as another independent variable.

[0064] The force field function curve of the initial ideal test system comprises a first curve and a second curve, the independent variable of the first curve is the second dimensionless quantity, the dependent variable of the first curve and the second curve is the first dimensionless quantity, and the independent variable of the second curve is the third dimensionless quantity. That is, the first curve represents the relationship between the suspension force and the sinking amount, and the second curve represents the relationship between the suspension force and the vehicle speed.

[0065] In step S203, the magnetomotive force of the superconducting magnet of the initial ideal test system and the resistivity of the ground coil are configured according to the force field function curves of the initial ideal test system and the actual train system, so that the shape matching degree of the force field function curve of the configured ideal test system and the force field function curve of the actual train system exceeds the preset limit.

[0066] An exemplary, Figure 6 An ideal test system and an actual train system are exemplified, Figure 7 An ideal test system and an actual train system are exemplified, Figure 6 And Figure 7 As shown in the figure, the shape matching degree of the two curves exceeds the preset limit, which can represent that the shapes of the two curves are approximately consistent, and in this case, the parameters of one system can be mapped from the parameters of the other system. In one possible implementation, when the magnetomotive force of the permanent magnet of the ideal test system is increased, the ground current can be increased in a proportional manner to compensate for the increase. In addition, the resistance of the ground coil can be modified to change the time constant L / R of the ground coil, thereby changing the time-varying characteristics, so that the function curves are consistent in the form of parameterized frequency.

[0067] In step S204, the first mapping relationship is determined based on the test system and the configured ideal test system.

[0068] In step S205, the reduction factor that makes the ideal test system and the actual train system satisfy the preset condition is determined.

[0069] The preset condition comprises that the solution obtained by performing a space-time linear transformation on the solution of the dynamic equation of the actual train system is the solution of the dynamic equation of the ideal test system, that is, the actual train system and the ideal test system have similar solutions.

[0070] In step S206, the second mapping relationship is determined based on the determined reduction factor.

[0071] In step S207, the parameter mapping relationship is established according to the first mapping relationship and the second mapping relationship.

[0072] In one or more embodiments provided in the present application, the coil module 400 includes a coil mounting seat 410 and a coil unit 420, the coil mounting seat 410 includes a plurality of and is respectively arranged on both sides of the vehicle carrying platform 200, and the coil unit 420 is arranged on the coil mounting seat 410.

[0073] On the basis of the above, before obtaining the test parameters from the test requirements of the high-temperature superconducting electric suspension engineering sample vehicle, the following can also be included:

[0074] Step S301, determine the platform test parameters.

[0075] The platform test parameters include the vehicle weight, electric suspension speed, static suspension height, sinking amount of the superconducting magnet 110 and the coil module 400, mechanical gap, single suspension time, maximum suspension force, maximum guiding force, maximum traction force, allowable static suspension coil maximum temperature rise, and maximum preparation time of the high-temperature superconducting electric suspension vehicle 100.

[0076] Among them, parameter index 1, the whole vehicle weight m of the high-temperature superconducting electric suspension vehicle to be tested; m=5T;

[0077] Parameter index 2, the speed range V of the high-temperature superconducting electric suspension vehicle to be tested min ~V max ;V min =30km / h, V max =660km / h;

[0078] Parameter index 3, static suspension height H max ;H max =300mm;

[0079] Parameter index 4, the maximum sinking amount (sinking amount refers to the distance that the center line of the superconducting magnet 110 is lower than the center line of the coil unit 420) h of the center line of the superconducting coil and the center line of the static suspension exciting coil max ;h max =100mm;

[0080] Parameter index 5, mechanical gap (gap between the outer surface of the superconducting magnet 110 and the track) Δx; Δx=77mm;

[0081] Parameter index 6, the minimum speed V0 of static suspension min ;V0 min =30km / h;

[0082] Parameter index 7, the maximum duration t of single suspension max ;t max =3min;

[0083] Parameter index 8, the maximum suspension force F1max , guiding force F2 max , traction force F3 max ; F1 max = 40000 N, F2 max = 13300 N, F3 max = 4200 N;

[0084] Parameter index 9, maximum allowable temperature rise △T of static suspension coil max ; △T max = 100℃;

[0085] Parameter index 10, maximum preparation time t; t = 1h.

[0086] Step S302, superconducting magnet excitation and decay rate test.

[0087] Specifically, it can include: injecting current to the magnetic pole of the superconducting magnet 110, increasing the magnetic field strength of the magnet, until the target magnetic motive force is reached, the target magnetic motive force is 700Ka; after the excitation is completed, the magnetic field decay rate of the superconducting magnet 110 is detected, and it is judged whether the magnetic field decay rate is less than a preset decay rate threshold, if yes, step 3 is executed, otherwise, the superconducting magnet 110 excitation and decay rate test is performed again.

[0088] Exemplarily, after the excitation of the first step is completed, the data T1 of the superconducting magnet 110 after the magnetic field is stable is measured and recorded; after the superconducting magnet 110 magnetic field continuously decays for 2-3 days, several stages are taken to measure and record the current magnetic field data T2, and the daily decay rate of the current magnetic field T1-T2 / T1 is calculated to verify the current magnet magnetic field strength capability; if the magnetic field decay rate is less than the decay rate threshold, such as 2%, it can be represented that the superconducting magnet 110 is in a medium-long working state, which meets the magnetic field decay rate requirement, and the next test step can be performed; if it is not less than the decay rate threshold, the excitation and decay rate test needs to be performed again.

[0089] Step S303, determining the lifting height threshold of the vehicle carrying platform.

[0090] Wherein, the lifting height threshold is determined according to the static suspension height and the sinking amount of the superconducting magnet 110 and the coil module 400. Specifically, the displacement space value N of the vertical freedom degree of the vehicle carrying platform 200 is solved by the following formula: N = H max + h max = 400 mm; then the suspension height threshold of the train high-temperature superconducting electric suspension vehicle 100 is given, within the maximum displacement space value of the vertical freedom degree of the vehicle carrying platform 200, the high-temperature superconducting electric suspension vehicle 100 can adjust different suspension heights according to different suspension speeds. According to the speed range V min ~Vmax The levitation height range can be determined.

For example, the three different working conditions determined according to the maximum suspension force F1 max , the maximum guiding force F2 max and the maximum traction force F3 max correspond to the load at the peak value of the suspension force. Whether the static strength and rigidity of the vertical contact position, the horizontal contact position and the longitudinal contact position of the coil mounting seat 410 and the coil unit 420 meet the requirements, that is, whether the maximum Mises stress is less than the material yield strength and the deformation is less than 1 mm.
