Description

Technical Field

[0001] This application relates to the field of rail vehicle technology, and more specifically, to a method and apparatus for calculating the length and exit height of the jumper wire of an articulated light rail vehicle. Background Technology

[0002] The jumper cables used to connect power, control, and communication cables between adjacent cars on urban rail vehicles swing back and forth as the vehicles move along the track. If the cable length is chosen too long during the design phase, it will result in significant waste and increased project costs, and there is also a risk of the cables rubbing against surrounding equipment. Conversely, if the length is too short, the cables will be stretched during vehicle operation, leading to loose connections or breakage. Therefore, selecting the appropriate jumper cable length during the design phase is crucial.

[0003] Currently, during the design phase, drawing software is used to draw or simulate the operating status of urban rail vehicles under different line conditions, and then the length of the jumper wire is obtained with the help of drawing software. However, this method requires a large amount of work and places high demands on the designer's experience. Summary of the Invention

[0004] To address the aforementioned issues, the purpose of this application is to provide a method and apparatus for calculating the length of the jumper cable and the height of the cable exit in an articulated light rail vehicle.

[0005] In a first aspect, embodiments of this application provide a method for calculating the length and outlet height of the jumper cable of an articulated light rail vehicle, including:

[0006] Obtain the track condition parameters and vehicle technical parameters of the articulated light rail vehicle;

[0007] Based on the obtained line condition parameters and vehicle technical parameters, determine the length of the articulated light rail vehicle jumper wire;

[0008] Based on the determined length of the articulated light rail vehicle jumper cable, the outgoing cable height of the articulated light rail vehicle jumper cable is obtained.

[0009] Secondly, embodiments of this application also provide a device for calculating the length of the jumper cable and the height of the cable exit in an articulated light rail vehicle, comprising:

[0010] The acquisition module is used to acquire the track condition parameters and vehicle technical parameters of the articulated light rail vehicle;

[0011] The determination module is used to determine the length of the articulated light rail vehicle jumper wire based on the obtained line condition parameters and vehicle technical parameters;

[0012] The processing module is used to obtain the outgoing height of the articulated light rail vehicle jumper line based on the determined length of the jumper line.

[0013] Thirdly, embodiments of this application also provide a computer-readable storage medium storing a computer program, characterized in that the computer program, when run by a processor, performs the steps of the method described in the first aspect above.

[0014] Fourthly, embodiments of this application also provide an electronic device, the electronic device including a memory, a processor and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the processor using the steps of the method described in the first aspect above.

[0015] In the solutions provided by the first to fourth aspects of this application, the length of the articulated light rail vehicle jumper wire is determined based on the obtained track condition parameters and vehicle technical parameters. Based on the determined length of the articulated light rail vehicle jumper wire, the exit height of the jumper wire is obtained. Compared with the method of obtaining the jumper wire length using drawing software in related technologies, the length and exit height of the articulated light rail vehicle jumper wire can be determined using track condition parameters and vehicle technical parameters. This allows for a quick and convenient acquisition of a suitable jumper wire length selection range and a reasonable jumper wire exit point height without the need for drawing software. It also requires less experience from the designer. Only the relevant basic vehicle parameters and track conditions need to be changed between different projects, resulting in high convertibility and a corresponding reduction in design workload and improved design efficiency.

[0026] The jumper cables used to connect power, control, and communication cables between adjacent cars on urban rail vehicles swing back and forth as the vehicles move along the track. If the cable length is chosen too long during the design phase, it will result in significant waste and increased project costs, and there is also a risk of the cables rubbing against surrounding equipment. Conversely, if the length is too short, the cables will be stretched during vehicle operation, leading to loose connections or breakage. Therefore, selecting the appropriate jumper cable length during the design phase is crucial.

[0027] Currently, during the design phase, drawing software is used to draw or simulate the operating status of urban rail vehicles under different line conditions, and then the length of the jumper wire is obtained with the help of drawing software. However, this method requires a large amount of work and places high demands on the designer's experience.

[0028] Based on this, the following embodiments of this application disclose a method and apparatus for calculating the length and exit height of the jumper wire in an articulated light rail vehicle. The method includes the following steps: calculating the distance between the exit points of the jumper wire between adjacent car bodies in the articulated light rail vehicle under extreme conditions, based on track conditions and basic vehicle technical parameters; obtaining a lower limit value for the jumper wire length by leaving a certain margin based on the maximum distance; then obtaining an upper limit value for the jumper wire length using the catenary equation, radius of curvature formula, and the maximum possible minimum bending radius of the jumper wire, thereby obtaining a range for selecting the jumper wire length; selecting a suitable wire length within this range as the jumper wire length; and combining vehicle clearance and other constraints to obtain a suitable exit height for the jumper wire based on this wire length. This method can theoretically calculate the length and exit height of the jumper wire when the roof of an articulated vehicle is jump-connected, effectively improving calculation accuracy and design efficiency, and is simple and easy to implement.

[0029] The aforementioned extreme case refers to the situation when the articulated light rail vehicle is located in the section of the track with the minimum turning radius.

[0030] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Example 1

[0033] See Figure 1 The flowchart shown illustrates a method for calculating the length and outlet height of a jumper cable on an articulated light rail vehicle. This embodiment proposes a method for calculating the length and outlet height of a jumper cable on an articulated light rail vehicle, including the following specific steps:

[0034] Step 100: Obtain the track condition parameters and vehicle technical parameters of the articulated light rail vehicle.

[0035] In step 100 above, the track condition parameters and vehicle technical parameters of the articulated light rail vehicle are pre-cached in the server.

[0036] See Figure 2 The diagram shown illustrates the technical parameters of two adjacent car bodies of a light rail vehicle operating on a section of the track with a minimum turning radius R. Figure 2In the vehicle technical parameters shown, a represents the distance between the centers of two adjacent bogies in each articulated unit of the articulated light rail vehicle; b represents the distance from the center of the articulated device to each adjacent car body in the articulated light rail vehicle; c represents the car body width; R represents the track radius under extreme conditions (abbreviated as: track radius); d min d represents the minimum distance between adjacent car bodies in an articulated light rail vehicle. max θ1 represents the maximum distance between adjacent car bodies in an articulated light rail vehicle; θ2 represents the first angle between the axis of symmetry of the adjacent car body and the longitudinal centerline of any car body in the adjacent car body; θ3 represents the second angle between the line connecting the centers of the adjacent car bodies and any car body in the adjacent car body.

[0039] Specifically, d in the above parameters min d max θ1 and θ2 are obtained through calculation, and the specific calculation formula is as follows:

[0040]

[0041]

[0042]

[0043] Here, the track condition parameters include, but are not limited to, the track radius.

[0044] Step 102: Determine the length of the articulated light rail vehicle jumper wire based on the obtained line condition parameters and vehicle technical parameters.

[0045] Specifically, in order to determine the length of the articulated light rail vehicle jumper wire, step 102 above can be performed by following steps (1) to (5):

[0046] (1) Obtain the pre-set exit point of the articulated light rail vehicle jumper and the first distance between the exit point and the end wall of the vehicle body near the articulated device, and the second distance between the exit point and the longitudinal centerline of the vehicle body where the exit point is located.

[0047] (2) The minimum and maximum spacing between the exit points of the connecting lines of adjacent car bodies when the articulated light rail vehicle is running on a section of the track with the minimum turning radius are calculated using the following formula:

[0048]

[0049]

[0050] Where, d ij_min This indicates the minimum distance between the outgoing points of the jumper wires of adjacent vehicle bodies; d ij_max θ1 represents the maximum distance between the exit points of the connecting wires between adjacent car bodies; θ2 represents the first included angle; θ2 represents the second included angle; b represents the distance from the center of the articulated device to each adjacent car body in the articulated light rail vehicle; d represents the distance from the center of the articulated device to each adjacent car body in the articulated light rail vehicle. i Indicates the first distance; d j Indicates the second distance;

[0051] (3) The minimum length of the articulated light rail vehicle's jumper line is calculated using the following formula:

[0052] L min =d ij_max +y

[0053] Among them, L min y represents the minimum length of the jumper cable for articulated light rail vehicles; y represents the length allowance.

[0054] (4) Obtain the minimum bending radius of the jumper wire, and calculate the maximum length of the jumper wire of the articulated light rail vehicle based on the obtained minimum bending radius of the jumper wire.

[0055] (5) Determine a length value from the range of the minimum length of the articulated light rail vehicle jumper wire and the maximum length of the articulated light rail vehicle jumper wire as the length of the articulated light rail vehicle jumper wire.

[0056] In step (1) above, the first distance and the second distance are parameters that meet the design requirements of the articulated light rail vehicle. These parameters are set by the staff according to the design requirements of the articulated light rail vehicle and are stored in the server in advance.

[0057] In step (3) above, the length margin is pre-cached in the server.

[0058] In step (4) above, specifically, in order to calculate the maximum length of the articulated light rail vehicle jumper wire, the following steps (41) to (42) can be performed:

[0059] (41) Obtain the minimum bending radius of the jumper wire;

[0060] (42) The maximum length of the articulated light rail vehicle's jumper line is calculated using the following formula:

[0061]

[0062] Among them, L max This indicates the maximum length of the jumper cable for articulated light rail vehicles; ρ minThis indicates the minimum bending radius of the jumper wire.

[0063] In step (41) above, the minimum bending radius of the jumper wire is pre-stored in the server.

[0064] After determining the length of the articulated light rail vehicle jumper wire, the following step 104 can be performed to obtain the outgoing height of the articulated light rail vehicle jumper wire.

[0065] Step 104: Based on the determined length of the articulated light rail vehicle jumper wire, obtain the outgoing height of the articulated light rail vehicle jumper wire.

[0066] Specifically, in order to obtain the exit height of the articulated light rail vehicle jumper cable, step 104 above can perform the following steps (11) to (14):

[0067] (11) Calculate the catenary coefficient of the catenary equation using the following formula:

[0068]

[0069] Where L represents the length of the articulated light rail vehicle's jumper cable; k represents the catenary coefficient;

[0070] (12) The maximum sag height of the articulated light rail vehicle's crossover line is calculated using the following formula:

[0071]

[0072] Among them, h max This indicates the maximum sag height of the jumper line on the articulated light rail vehicle.

[0073] (13) Obtain the maximum wire diameter of the jumper wire, the height difference between the mounting surface of the jumper wire outlet and the highest mounting point of the interference component below the jumper wire, and the installation height difference margin;

[0074] (14) The minimum exit height of the articulated light rail vehicle's crossover line is calculated using the following formula:

[0075]

[0076] Among them, h min h1 represents the minimum exit height of the jumper cable for articulated light rail vehicles; h2 represents the height difference between the mounting surface of the jumper cable exit point and the highest mounting point of the interference component below the jumper cable; d represents the maximum wire diameter of the jumper cable.

[0077] In step (13) above, the maximum wire diameter of the jumper wire, the height difference between the installation surface of the jumper wire outlet and the highest installation point of the interference component below the jumper wire, and the installation height difference margin are all parameters that meet the design requirements of the articulated light rail vehicle, and are all stored in the server in advance.

[0078] In general, there are multiple jumper wires, resulting in the outgoing wire height h. min This can be determined based on the outermost jumper wire, because for other jumper wires, the maximum possible height of the outlet point from the lowest point of the jumper wire is greater than h. max Small, therefore, this height is suitable for all jumper wires.

[0079] See Figure 3 The schematic diagram of the jumper cable arrangement shown is the result of setting the jumper cable arrangement based on the calculation method of the jumper cable length and exit height of the articulated light rail vehicle proposed in this embodiment.

[0080] The calculation method for the jumper length and exit height of the articulated light rail vehicle described in this embodiment can quickly and conveniently obtain a suitable range for jumper length selection and a reasonable exit point height without the need for drawing software. It requires less experience from the designer and only requires changes to the relevant basic vehicle parameters and track conditions between different projects, resulting in high convertibility and a corresponding reduction in design workload.

[0081] In summary, this embodiment proposes a method for calculating the length and exit height of the articulated light rail vehicle's jumper cable. Based on the obtained track condition parameters and vehicle technical parameters, the length of the articulated light rail vehicle's jumper cable is determined, and the exit height is obtained based on this determined length. Compared to related technologies that rely on drawing software to obtain the jumper cable length, this method uses only track condition parameters and vehicle technical parameters to determine the length and exit height of the articulated light rail vehicle's jumper cable. It allows for a quick and convenient determination of a suitable jumper cable length range and a reasonable jumper cable exit point height without the need for drawing software.
