Abstract
Description
Technical Field
[0001] This application belongs to the field of normal-conducting maglev turnouts, and in particular relates to a method and device for designing the alignment of a flexible and bendable normal-conducting maglev turnout. Background Technology
[0002] Compared to conventional rail systems, maglev rail transit features low noise, low energy consumption, high speed, and high efficiency, and is considered a promising new mode of transportation. Maglev turnouts, as a key component for track switching in maglev trains, play a vital role in the safe and stable operation of the train. Maglev turnouts differ significantly from railway turnouts, primarily employing a flexible, bendable design. In essence, a maglev turnout is a continuous, elastically bendable steel beam, driven by hydraulic or electromechanical mechanisms to switch from a straight track to a side track.
[0003] The planar alignment design of a turnout is the first step in turnout design, a crucial prerequisite for ensuring the safe passage of vehicles, and an important basis for the structural design of the turnout. A search of existing patents related to maglev turnout alignment reveals that patent CN112507412A discloses a method for achieving a deflection curve shape for a high-speed maglev turnout, and patent CN212809214U discloses a deflection curve high-speed maglev turnout. Both patents focus on achieving beam deflection by applying loads to obtain the alignment, but their operability in specific alignment design is relatively low. Patent CN202310607542.4 discloses an articulated maglev turnout structure and turnout alignment, mainly targeting the structural design of low-speed turnouts. Patent CN111576101B discloses a support point layout for a high-rigidity high-speed maglev turnout. The patents CN114440784B and CN202310852822.1 disclose a turnout configuration and arrangement method, focusing on the design of the turnout support point arrangement structure. CN114440784B discloses an adaptive high-speed maglev turnout with spatial alignment reconstruction function, focusing on the use of fiber optic grating array sensors to perceive the overall turning alignment of a side-bending high-speed maglev turnout. CN202310852822.1 discloses a maglev turnout alignment and its construction method, focusing on the geometric relationships that the alignment construction needs to satisfy. The specific implementation method needs further clarification, and the factors considered in the turnout alignment design are not yet perfect, resulting in limitations in feasibility and applicability.
[0004] In summary, there are virtually no patents available for specific and feasible design methods for the turnout alignment of conventional maglev trains. Furthermore, the "High-Speed Maglev Transportation Design Standard" (CJJ / T310-2021) only specifies the turnout alignment parameters for lateral passing speeds of 98 km / h and 196 km / h, without clearly defining specific turnout alignment design methods. Moreover, these two turnout types are insufficient to meet the actual engineering requirements for turnouts with different levels of lateral passing speeds. Summary of the Invention

[0014] Thirdly, this application provides an electronic device, including the flexible bendable normal-conducting maglev turnout alignment design device as described above.
[0015] Fourthly, this application provides a computer-readable storage medium, characterized in that the computer-readable storage medium stores at least one piece of program code, which is executed by a processor to implement the flexible bendable normal-conducting maglev turnout alignment design method as described in any of the preceding claims.
[0016] The beneficial effects of the technical solution provided in this application include: (1) The present invention proposes a flexible bendable normal-conducting maglev turnout alignment design method and turnout, which clarifies the complete design process from static modeling - track geometry constraints - precise parameter calculation - multi-dimensional verification - optimal solution selection. The steps are clear and the logic is closed-loop, which transforms the abstract alignment design into a quantifiable and reproducible engineering method. It solves the core pain point of "lack of specific and feasible design method for normal-conducting high-speed maglev turnout alignment" in the prior art. It breaks through the limitation of the "High-speed Maglev Transportation Design Standard" (CJJ / T310-2021) which only specifies two kinds of lateral speed turnout parameters. Through the design logic of "lateral acceleration step value + actual radius dynamic adjustment + standardized adaptation of transition curve and circular curve length", it realizes the serial design of turnouts with different levels of lateral passing speed, which can cover the engineering needs of the whole scenario from low speed to high speed, and solves the problem of "single demand adaptation" of existing turnouts.
[0017] (2) The present invention proposes a design method for the linear shape of an elastic bendable normal-conducting maglev turnout and the turnout itself. The design process takes into account static performance (stress control), track geometry matching (suspension guidance, running gear adaptation, secondary suspension constraint), and dynamic stability (natural frequency, dynamic response). This ensures that the linear shape not only meets geometric requirements but also adapts to the structural strength of the turnout and the safety of vehicle passage, thus avoiding the defects of the prior art that "only considers geometric relationships and ignores the actual engineering adaptability".
[0018] (3) The present invention proposes a method for designing the alignment of a flexible bendable normal-conducting maglev turnout and the turnout itself. The key parameters are designed in strict accordance with the actual engineering and specification requirements. The lengths of all alignment segments (transition curves + straight sections, circular curves) are adjusted to integer multiples of the standard stator unit length of 1.032m for maglev tracks, which reduces the error risk in turnout beam manufacturing and on-site installation and improves the feasibility of the design scheme.
[0019] (4) The present invention proposes a design method and turnout for a flexible bendable normal-conducting maglev turnout. By using static finite element modeling and machine learning to fit the stress function, the minimum beam length and minimum radius are determined to avoid excessive bending stress of the turnout beam. By using track geometry constraints, the minimum planar curve radius is specified to be ≥350m, ensuring compliance of the lateral clearance of the guide electromagnet, controllable deformation of the chain running part spring, and no excessive lateral displacement of the car body. The lateral acceleration time-varying rate is verified to be ≤2.0m / s³ by the length of the transition curve. By using the design of "circular transition ratio optimization + curve length not less than vehicle length", the single car body avoids crossing three types of track at the same time, ensuring smooth transition of the train track. At the same time, by limiting the lateral acceleration to ≤2.0m / s², the vibration and lateral sway of the car body are reduced, improving passenger comfort and safety.
[0020] (5) The present invention proposes a method for designing the alignment of a flexible bendable normal-conducting maglev turnout and the turnout itself. Under the premise of satisfying all constraints, the optimal alignment with the "minimum total length of the turnout" is selected to effectively reduce the amount of material used in the turnout beam, shorten the space occupied by the line, reduce the cost of turnout manufacturing, transportation and engineering construction, and take into account both technological advancement and economic rationality.
[0021] (6) The present invention proposes a method for designing the alignment of an elastic bendable normal-conducting maglev turnout and the turnout itself. The design parameters are flexible and adjustable. The lateral acceleration is precisely measured in steps of 0.00001. The relevant parameters of the circular curve (circular gradient ratio, circular curve length or corresponding central angle of the circular curve) are accurately measured. The turnout can be customized according to the lateral velocity requirements, site space constraints and turnout structural parameters (such as material yield strength and beam stiffness) of different projects, making it more adaptable.
[0022] (7) The elastic bendable normal-conducting maglev turnout alignment design method and turnout proposed in this invention, the core design logic (static constraints - geometric parameter calculation - multi-dimensional verification - optimal solution screening) is not only applicable to single turnouts, but can also be directly extended to derivative types such as three-way turnouts, five-way turnouts, single crossover turnouts, and single circular turnouts with low lateral passing speed. There is no need to make essential modifications to the design method, only to adjust the alignment combination form. It provides a unified design paradigm for the diversified track changing needs in the maglev rail transit network, which is conducive to technology promotion and standardization.

Determine the length of the arc segment The relationship between the length of the transition curve segment and the length of the transition curve segment is used as the second relationship.
[0029] In some examples, step S101 includes: Let the length of the curve segment that transitions to the first transition curve segment be . The length of the first straight segment connecting to the first transition curve segment is The length of the second transition curve segment is The length of the second straight segment that connects to the second transition curve segment is .
[0030] According to the specifications, the system length of the track beam should be an integer multiple of 1.032m, which is the length of the standard stator unit. + and + It should be an integer multiple of 1.032m, the standard stator unit length, referring to existing specifications. Generally, 0.5m is taken. The standard value is 1.084m. and Other design values can also be selected according to actual needs.
[0031] The length of the first straight segment is determined based on the input. Length of the second straight segment ,calculate Divide by 1.032 and round up to get ; and then through and The curve length of the first transition curve segment in the actual design is calculated.

[0034] That is, the second relation of this application is: .
[0035] S102. Determine the constraint conditions for the turnout beam, including the minimum length. Minimum radius of the arc segment .
[0036] S1021. Determine the minimum length of turnout beam alignment design from a static stress perspective. and minimum radius .
[0037] In some examples, S1021 includes: The first step is to establish a refined finite element analysis model for high-speed maglev turnout beams of different lengths, and then perform simulations based on the refined finite element analysis model to obtain several lengths including the turnout beams. Lateral displacement of the beam ends of the turnout beam Maximum stress value of turnout beam The samples are used to form a dataset.
[0038] The model dimensions are taken according to the actual design values. Each component of the model is simulated using solid elements. One end of the model is fixed, and a displacement load perpendicular to the beam axis is applied to the other end, with a displacement of not less than 3.5m.
[0039] Calculate different lengths Lateral displacement of turnout beam at different beam ends The maximum stress value under a displacement load of not less than 3.5m. This results in several training samples, each consisting of a set of turnout beam lengths. Lateral displacement of the beam ends of the turnout beam Maximum stress value of turnout beam The data composition.
[0040] The second step is to fit several samples from the dataset to obtain the length of the turnout beam. Lateral displacement of the beam ends of the turnout beam Maximum stress value of turnout beam The functional relationship.
[0041] Among them, machine learning algorithms are used to fit the stress values in the dataset. Length of turnout beam Lateral displacement at beam end The functional relationship, that is .
[0042] Step 3: Determine the minimum length of the turnout beam based on the aforementioned functional relationship. .
[0043] Considering a certain safety factor , The yield strength of the turnout beam material, and the allowable design stress of the turnout beam. Maximum stress value .
[0044] According to the functional relationship This allows us to determine the different lateral displacements at the beam ends. The length of the corresponding turnout beam .
[0045] It is foreseeable that stress and It shows a certain positive correlation with the length of the turnout beam. There is a certain negative correlation. The shortest beam length of the turnout beam can be calculated using a functional relationship, denoted as . .
[0046] Step 4: Based on the minimum length of the turnout beam The displacements of each point on the turnout beam are extracted to obtain the specific alignment of the turnout beam. The minimum radius of the circular arc segment of the turnout beam is then calculated using derivative relationships. .
[0047] By extracting the displacements of various points on the turnout beam, the specific alignment of the turnout beam is obtained, and then the minimum radius of the turnout curve is calculated using derivative relationships. .
[0048] Due to the limitation of the bending capacity of the turnout beam, conventional missile-type bendable maglev turnouts have a minimum beam length as mentioned above. The corresponding turnout curve (circular arc segment) The minimum radius of ) is denoted as The corresponding lateral passing speed is denoted as , In the formula, This indicates lateral acceleration.
[0049] S1022. Minimum radius of turnout determined by the geometric constraints of the track alignment. .
[0050] (1) Requirements of stable suspension guidance on turnout curve radius: When the electromagnet is on a circular curve, the lateral clearance between the end of the guide electromagnet on the outer rail side and the rail is large, while the lateral clearance in the middle is small, and the opposite is true on the inner rail side.
[0051] To ensure the safe passage of the suspension frame, the minimum lateral clearance between the guide electromagnet and the track must be no less than 6mm and the maximum clearance must not exceed 14mm.
[0052] The guide electromagnet module of the conventional high-speed maglev vehicle is 3.096m long to ensure that there is no lateral collision between the magnetic tracks. The calculation shows that the radius of the turnout plane curve should be greater than 149.773m.
[0053] (2) Requirements of the chain-type running gear for the curve radius of the turnout When the chain-type traveling part passes through the curved track, the longitudinal distance between the inner and outer sides of the adjacent suspension frame will decrease and increase respectively. Since the electromagnet is approximately a rigid body, the metal rubber spring at the overlap point will deform to adapt to the change in longitudinal distance.
[0054] On circular curve tracks, the deformation of metal-rubber springs is the greatest, and the radius of the turnout plane curve needs to be greater than 343.66m.
[0055] (3) Requirements of the secondary suspension system of the vehicle for the turnout curve radius When the vehicle is on a curve, the vehicle body always remains straight, while the running gear is arranged in a zigzag pattern. The lateral displacement of the vehicle body relative to the suspension frame is limited by the secondary lateral springs.
[0056] When the lateral displacement of the car body relative to the running gear is too large, it will come into contact with the lateral limit spring of the secondary system, affecting the lateral response of the car body. Therefore, it is necessary to ensure that the lateral displacement of the car body relative to the running gear is less than the lower limit of the limit spring when the vehicle passes through the turnout curve.
[0057] Calculations based on geometric constraint equations show that for a single high-speed maglev vehicle to safely pass through a curved section, the radius of the turnout plane curve must be greater than 329.49m.
[0058] In summary, due to the geometric constraints of the track alignment, the radius of the planar curve of the turnout should not be less than the radius of the circular curve of 350.00m.

Then, obtain several sets of length parameter combinations for the first straight line segment, the second straight line segment, the first transition curve segment, the second transition curve segment, and the arc segment.
[0069] S105. Based on the minimum curve length of the transition curve segment. The calculated combinations of length parameters are verified, and combinations of length parameters that do not meet the requirements in the initial parameter set are eliminated.

[0104] According to the specifications, the length of the turnout beam must be an integer multiple of 1.032. Therefore, the curve length of the transition section plus the length of the straight section, and the curve length of the circular arc section should all be integer multiples of 1.032. The above process ensures that the curve length of the transition section plus the straight section is an integer multiple of 1.032. Regarding the curve length of the circular arc section...

[0106] S107. Perform simulation based on the simulation parameter set, and eliminate the length parameter combinations and corresponding coordinate parameter combinations in the simulation parameter set that do not meet the mechanical performance requirements to obtain the target parameter set.
[0107] In some examples, step S107 includes: A high-speed maglev train-turnout coupled dynamic model is established based on the combination of geometric design parameters in the design parameter set. Numerical simulation is then performed based on the high-speed maglev train-turnout coupled dynamic model to obtain several dynamic response indices. Subsequently, the dynamic performance, deflection, throughput performance, and natural frequency of the turnout are analyzed based on the dynamic response indices, and geometric design parameters that meet the performance requirements are selected.
[0108] In some examples, the numerical simulation method includes any one of the following: quadratic filtering, trigonometric series, white noise filtering, and inverse Fourier transform.
[0109] After determining the key design parameters of the track alignment, a magnetic levitation coupling analysis model and a modal analysis model were established for the train-turnout-subfoundation system. The dynamic performance of the turnout system, the deflection of the turnout beam, the turnout throughput performance, and the natural frequency were calculated to determine whether they meet the specifications. The first-order natural frequency was also considered. , This represents the maximum lateral passing speed of the turnout. This refers to the span of a single-span turnout beam.
[0110] The overall alignment parameters of the turnout beam are determined according to the alignment parameters determined by the above method, and the specific structural parameters are determined according to the actual engineering design parameters. The finite element model is established using solid elements.
[0111] Referring to the structure of the TR08 high-speed maglev vehicle, this application provides a schematic diagram of the model structure, see [link / reference]. Figure 3 and Figure 4 The vehicle body 11, bolster 12, swing arm 13, and braking electromagnet 14 are considered as rigid bodies. The established flexible levitation electromagnet 15 and flexible guide electromagnet 16 are connected to the support arm of the flexible suspension frame 17 via spring-damping force elements. The air spring between the bolster and the suspension frame is simplified to a linear spring-damper, forming a dynamic model of the running gear for the flexible model. Replacing the levitation electromagnet 15 and guide electromagnet 16 with rigid bodies forms a dynamic model of the running gear for the rigid-flexible model. Further replacing the flexible suspension frame 17 with a rigid suspension frame 17 established in the section forms a dynamic model of the running gear for the rigid model.
[0112] The rigid model has 185 degrees of freedom, the rigid-flexible model has 245 degrees of freedom (165 rigid body degrees of freedom + 80 flexible body modes), and the flexible model has 705 degrees of freedom (165 rigid body degrees of freedom + 540 flexible body modes).
[0113] To facilitate results analysis, the four suspension frames of the vehicle are designated as the first to fourth suspension frames from front to back, and the suspension (guiding) electromagnets are designated as the first to seventh suspension (guiding) electromagnets on the left or right side.
[0114] Using finite element software, a high-speed maglev car-turnout coupled dynamic model, a detailed vehicle dynamic model, and suspension and guidance control that are consistent with reality were built.
[0115] Application of unevenness at high-speed maglev turnouts: The track irregularity spectrum describes the functional relationship between the wavelength and amplitude of track irregularities, reflecting the smoothness and quality of the track. It can also serve as an important input excitation for the dynamic analysis of vehicle-track systems and is widely used in the dynamic simulation and modeling of vehicle systems. However, the obtained track spectral density function is all in the frequency domain, and the spatial or time domain sequence of track irregularities needs to be obtained through numerical simulation for use in vehicle simulation operation analysis.
[0116] In some examples, the numerical simulation method used in this application includes any one of the following: quadratic filtering method, trigonometric series method, white noise filtering method, and inverse Fourier transform method.
[0117] Among them, the inverse Fourier transform has good versatility and high computational accuracy, and can be well applied to the numerical simulation of random processes of railway track irregularities.
[0118] In some examples, the power spectrum is inverted using the inverse Fourier transform method. The inversion steps are as follows: The first step is to convert the track irregularity spectrum of high-speed maglev into a two-sided spectrum. Let the total time position of the simulated time series be... The time interval is Then the number of sampling points in the time domain and frequency domain is .
[0119] The second step, based on the relationship between power spectral density and time series, yields:
[0120] In the formula, ; Indicates Fourier transform; This is represented as the simulated value of track irregularity at the nth mileage sampling point; This represents the power spectral density function of orbital irregularities with K as the independent variable; In Indicates the frequency domain sampling point index; In This indicates the frequency domain sampling interval.
[0121] The third step involves generating the spectral phase, which also exhibits randomness, by means of a uniform distribution between 0 and 2π. Let... It is an independent phase sequence, with the mean of each component being 0. Because the Fourier transform of a real sequence is a complex sequence (even-symmetric in the real part and odd-symmetric in the imaginary part), therefore... It is a complex sequence with a modulus of 1, therefore we can let:
[0122] In the formula, It follows a distribution between 0 and 2π. It represents the phase angle of the nth sampling point in the random phase sequence of the frequency domain spectrum of track irregularities.
[0123] Then, from the formula, we can obtain the spectrum value as follows:
[0124] In the formula: The frequency domain spectrum representing the orbital irregularity Random phase angle at each sampling point; .
[0125] (4) The simulated values can be obtained by performing an inverse Fourier transform on the spectrum value sequence:
[0126] In the formula, .
[0127] Numerical simulations of the power spectrum of orbital elevation irregularities were performed based on the aforementioned inverse Fourier transform. When the maximum wavelength of the inversion was 100 m, the time-domain waveforms before and after the inversion were as follows: Figures 5 to 8 As shown.
[0128] in, Figure 5 This is a comparison chart of the vertical inversion and actual measurement of the left rail. Figure 6 Comparison of right-rail vertical inversion and actual measurement. Figure 5 and Figure 6 Used for vertical inversion of orbits with a maximum wavelength of about 100m and comparison with actual measurements. Figure 7 This is a comparison chart of the left-side lateral inversion and actual measurement. Figure 8 This is a comparison chart of the right-side lateral inversion and actual measurement. Figure 7 and Figure 8 Used for orbital lateral inversion and comparison with actual measurements at a maximum wavelength of approximately 100m.
[0129] According to the above Figures 5 to 8 As shown, when the maximum wavelength of the inversion is 100m, the inverted odometer domain irregularity sample and the measured irregularity sample are in good agreement in both amplitude and phase. This is because the maximum measurement wavelength when measuring irregularities is approximately 100m, which is consistent with engineering practice, and the inverted irregularity sample is relatively reliable.
[0130] The above model enables coupled analysis of vehicle passing through the turnout. By outputting dynamic response indicators such as vehicle vibration acceleration, turnout vibration acceleration, and dynamic displacement, the dynamic performance of the turnout system, the deflection of the turnout beam, the turnout passing performance, and the dynamic response of the natural frequency can be analyzed.
[0131] S108. Minimize the turnout length in the target parameter set while satisfying the minimum length requirement. A set of length parameters and coordinate parameters are used as the design parameters for the turnout beam.
[0132] To improve the economy and applicability of turnouts, under the premise of meeting the above requirements, the minimum turnout length is determined. The corresponding alignment is the optimal turnout alignment.
[0133] The above method can be used to achieve the alignment design of a single turnout. For other types of turnouts derived from the single turnout, such as three-way turnouts, five-way turnouts, and single crossover turnouts, the same method can be used to achieve the alignment design.
[0134] Furthermore, this application introduces a circular gradient. As the only unknown parameter, the equation is derived from the turnout endpoint offset and solved for the circle ratio. Alternatively, the solution can be obtained by replacing it with the length of the circular curve or the central angle corresponding to the circular curve. The overall process and method are the same as those for solving the circular gradient.
[0135] For the design of single circular turnouts with low lateral passing speeds, the transition curve can be set to 0 according to the above steps, and the same design of the single circular turnout can be achieved.
[0136] Taking a lateral passing speed of v=50km / h as an example, the optimal turnout configuration is obtained through the above process and calculations as follows: Figure 9 As shown, referring to the standard expression, the lateral passing speed The main technical parameters of the turnout with a speed of 50 km / h are shown in the table below.
